Celiac disease is a digestive and immune disorder that can keep the body from absorbing necessary nutrients. “Our conception and awareness of celiac disease has evolved over the past few decades, but there are still aspects that remain poorly understood,” says Dr. Ciaran Kelly, medical director of the Celiac Center at Beth Israel Deaconess Medical Center and professor of medicine at Harvard Medical School.

Perhaps not surprisingly, misconceptions are widespread among the general public. One example? Many people assume that everyone who has celiac disease is plagued by abdominal pain, bloating, or diarrhea. But actually, many adults newly diagnosed with this inherited gluten intolerance don’t have these symptoms.

What’s more, gluten — the sticky protein found in grains such as wheat, barley, and rye — can cause gastrointestinal distress and other symptoms in people who don’t have celiac disease. Read on for a deeper dive into four myths and facts about celiac disease and related digestive conditions.

Myth # 1: Celiac disease is usually diagnosed at a young age

Not typically. While celiac disease can develop any time after a baby’s first exposure to gluten, it’s usually diagnosed much later in life. According to the National Celiac Association, the average age of diagnosis is between 46 and 56. Around 25% of people are diagnosed after age 60.

Celiac disease is slightly more common in women and among people with other autoimmune conditions, including type 1 diabetes, Hashimoto’s thyroiditis (a common cause of low thyroid levels), and dermatitis herpetiformis (a rare condition marked by an itchy, blistering rash).

“We don’t know why some people go from being susceptible to actually having celiac disease,” says Dr. Kelly. The prevailing theory is that some sort of physical or emotional stress — such as a viral infection, surgery, or anxiety from a stressful life event — may “flip the switch” and cause the disease to appear, he says. “Increasing numbers of people are being diagnosed at midlife and older, often after they’re found to have conditions such as anemia or osteoporosis caused by nutrient deficiencies,” says Dr. Kelly.

Myth #2: Celiac disease only affects the gut

When people have celiac disease, eating gluten triggers an immune system attack that can ravage the lining of the small intestine. A healthy small intestine is lined with fingerlike projections, called villi, that absorb nutrients. In celiac disease, the immune system attacks the villi, causing them to flatten and become inflamed — and thus unable to adequately absorb nutrients.

While gastrointestinal problems can occur, they aren’t always present. In fact, celiac disease can present with many different symptoms that affect the nervous, endocrine, and skeletal systems. A few examples are brain fog, changes in menstrual periods, or muscle and joint pain.

Myth # 3: Celiac disease versus gluten intolerance

If you feel sick after eating gluten, you probably have celiac disease, right? Actually, that may not be true. Some people have non-celiac gluten sensitivity (also called gluten intolerance), which can cause uncomfortable digestive symptoms after eating gluten. But gluten intolerance differs from celiac disease.

• Celiac disease is diagnosed with blood tests that look for specific antibodies. If antibodies are present, a definitive diagnosis requires an intestinal biopsy to look for signs of damage that characterize the condition.
• Non-celiac gluten sensitivity does not trigger antibodies or cause intestinal damage. Yet some people with this problem say they also experience brain fog, trouble concentrating, muscle aches and pain, and fatigue after eating gluten-containing foods.

“Non-celiac gluten sensitivity appears to be a real phenomenon, but it’s not well defined,” says Dr. Kelly. It’s unclear whether people experiencing it are intolerant to gluten or to something else in gluten-containing foods.

• One possibility is sugarlike molecules known as FODMAPs, which are found in many foods — including wheat. Short for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, gas and bloating can occur when gut bacteria feed on FODMAPs.
• Another possibility is an allergy to wheat, which can cause symptoms such as swelling, itching, or irritation of the mouth and throat after eating wheat. Other symptoms include a skin rash, stuffy nose, and headache, as well as cramps, nausea, and vomiting. Some people may develop a life-threating allergic reaction known as anaphylaxis.

Myth #4: A gluten-free diet always relieves the symptoms and signs of celiac disease

The sole treatment for celiac disease — adopting a diet that avoids all gluten-containing foods — doesn’t always help. This problem is known as nonresponsive celiac disease.

“About 20% of people with celiac disease have ongoing symptoms, despite their best efforts to stick to a gluten-free diet,” says Dr. Kelly. Others have intermittent signs and symptoms, particularly when they are accidentally exposed to gluten. Accidental exposures often happen when people eat prepared or restaurant foods that claim to be gluten-free but are not. Cross contamination with gluten-containing foods is another potential route.

Potential solutions to nonresponsive celiac disease are being studied. Three promising approaches are:

• Enzymes that break down gluten, which people could take alongside gluten-containing foods. “It’s a similar concept to the lactase pills taken by people who are lactose intolerant to help them digest dairy products,” says Dr. Kelly.
• Dampening the immune response to gluten by inhibiting an enzyme called tissue transglutaminase that makes gluten more potent as an antigen.
• Reprogramming the immune response to prevent the body from reacting to gluten.

If you suffer from the throbbing, intense pain set off by migraine headaches, you may well wonder which medicines are most likely to offer relief. A recent study suggests a class of drugs called triptans are the most helpful option, with one particular drug rising to the top.

The study drew on real-world data gleaned from more than three million entries on My Migraine Buddy, a free smartphone app. The app lets users track their migraine attacks and rate the helpfulness of any medications they take.

Dr. Elizabeth Loder, professor of neurology at Harvard Medical School and chief of the Division of Headache at Brigham and Women’s Hospital, helped break down what the researchers looked at and learned that could benefit anyone with migraines.

What did the migraine study look at?

Published in the journal Neurology, the study included self-reported data from about 278,000 people (mostly women) over a six-year period that ended in July 2020. Using the app, participants rated migraine treatments they used as “helpful,” “somewhat helpful,” or “unhelpful.”

The researchers looked at 25 medications from seven drug classes to see which were most helpful for easing migraines. After triptans, the next most helpful drug classes were ergots such as dihydroergotamine (Migranal, Trudhesa) and anti-emetics such as promethazine (Phenergan). The latter help ease nausea, another common migraine symptom.

“I’m always happy to see studies conducted in a real-world setting, and this one is very clever,” says Dr. Loder. The results validate current guideline recommendations for treating migraines, which rank triptans as a first-line choice. “If you had asked me to sit down and make a list of the most helpful migraine medications, it would be very similar to what this study found,” she says.

What else did the study show about migraine pain relievers?

Ibuprofen, an over-the-counter pain reliever sold as Advil and Motrin, was the most frequently used medication in the study. But participants rated it “helpful” only 42% of the time. Only acetaminophen (Tylenol) was less helpful, helping just 37% of the time. A common combination medication containing aspirin, acetaminophen, and caffeine (sold under the brand name Excedrin) worked only slightly better than ibuprofen, or about half the time.

When researchers compared helpfulness of other drugs to ibuprofen, they found:

• Triptans scored five to six times more helpful than ibuprofen. The highest ranked drug, eletriptan, helped 78% of the time. Other triptans, including zolmitriptan (Zomig) and sumatriptan (Imitrex), were helpful 74% and 72% of the time, respectively. In practice, notes Dr. Loder, eletriptan seems to be just a tad better than the other triptans.
• Ergots were rated as three times more helpful than ibuprofen.
• Anti-emetics were 2.5 times as helpful as ibuprofen.

Do people take more than one medicine to ease migraine symptoms?

In this study, two-thirds of migraine attacks were treated with just one drug. About a quarter of the study participants used two drugs, and a smaller number used three or more drugs.

However, researchers weren’t able to tease out the sequence of when people took the drugs. And with anti-nausea drugs, it’s not clear if people were rating their helpfulness on nausea rather than headache, Dr. Loder points out. But it’s a good reminder that for many people who have migraines, nausea and vomiting are a big problem. When that’s the case, different drug formulations can help.

Are pills the only option for migraine relief?

No. For the headache, people can use a nasal spray or injectable version of a triptan rather than pills. Pre-filled syringes, which are injected into the thigh, stomach, or upper arm, are underused among people who have very rapid-onset migraines, says Dr. Loder. “For these people, injectable triptans are a game changer because pills don’t work as fast and might not stay down,” she says.

For nausea, the anti-emetic ondansetron (Zofran) is very effective, but one of the side effects is headache. You’re better off using promethazine or prochlorperazine (Compazine), both of which treat nausea but also help ease headache pain, says Dr. Loder.

Additionally, many anti-nausea drugs are available as rectal suppositories. This is especially helpful for people who have “crash” migraines, which often cause people to wake up vomiting with a migraine, she adds.

What are the limitations of this migraine study?

The data didn’t include information about the timing, sequence, formulation, or dosage of the medications. It also omitted two classes of newer migraine medications — known as gepants and ditans — because there was only limited data on them at the time of the study. These options include

• atogepant (Qulipta) and rimegepant (Nurtec)
• lasmiditan (Reyvow).

“But based on my clinical experience, I don’t think that any of these drugs would do a lot better than the triptans,” says Dr. Loder.

Another shortcoming is the study population: a selected group of people who are able and motivated to use a migraine smartphone app. That suggests their headaches are probably worse than the average person, but that’s exactly the population for whom this information is needed, says Dr. Loder.

“Migraines are most common in young, healthy people who are trying to work and raise children,” she says. It’s good to know that people using this app rate triptans highly, because from a medical point of view, these drugs are well tolerated and have few side effects, she adds.

Are there other helpful takeaways?

Yes. In the study, nearly half the participants said their pain wasn’t adequately treated. A third reported using more than one medicine to manage their migraines.

If you experience these problems, consult a health care provider who can help you find a more effective therapy. “If you’re using over-the-counter drugs, consider trying a prescription triptan,” Dr. Loder says. If nausea and vomiting are a problem for you, be sure to have an anti-nausea drug on hand.

She also recommends using the Migraine Buddy app or the Canadian Migraine Tracker app (both are free), which many of her patients find helpful for tracking their headaches and triggers.

Recently, a friend asked me about tonsil stones. He has sore throats several times a year, which are instantly relieved by gargling to remove them. When I told him I thought tonsil stones were pretty rare, he asked: “Are you sure about that? My ear, nose, and throat doctor says they’re common as rocks.” (Get it? stones? rocks?)

It turns out, my friend and his doctor are on to something. Tonsil stones are surprisingly common and often quite annoying. Here’s what to know and do.

What are tonsil stones?

Tonsil stones (medical term: tonsilloliths) are small white or yellow deposits on the tonsils. They develop when bacteria, saliva, food particles, and debris from cells lining the mouth get trapped in tiny indentations called crypts.

They vary considerably between people, including:

• Size. They may be so small that you can’t see them with the naked eye. Or they may grow to the size of gravel or, rarely, much larger.
• Consistency. They’re often soft but may calcify, becoming hard as a rock. Hence, the name.
• How long they last. Tonsil stones can last days to weeks, or may persist far longer before they break up and fall out.
• How often they occur. New tonsilloliths may appear several times each month or just once or twice a year.

While they’re more likely to form if you have poor oral hygiene, good oral hygiene doesn’t provide complete protection. Even those who brush, floss, and see their dentists regularly can develop tonsil stones.

How common are tonsil stones?

You’ve heard of kidney stones and gallstones, right? Clearly, those conditions are better known than tonsil stones. Yet tonsil stones are far more common: studies suggest that up to 40% of the population have them. Fortunately, unlike kidney stones and gallstones, tonsil stones are usually harmless.

What are the symptoms of tonsil stones?

Often people have no symptoms. In fact, if tonsil stones are small enough, you may not even know you have them. When tonsil stones do cause symptoms, the most common ones are:

• sore throat, or an irritation that feels as though something is stuck in the throat
• bad breath
• cough
• discomfort with swallowing
• throat infections.

Who gets tonsil stones?

Anyone who has tonsils can get them. However, some people are more likely than others to form tonsil stones, including those who

• have tonsils with lots of indentations and irregular surfaces rather than a smooth surface
• smoke
• drink lots of sugary beverages
• have poor oral hygiene
• have a family history of tonsil stones.

How are tonsil stones treated?

That depends on whether you have symptoms and how severe the symptoms are.

• If you have no symptoms, tonsil stones may require no treatment.
• If you do have symptoms, gargling with salt water or removing tonsil stones with a cotton swab or a water flosser usually helps. Avoid trying to remove them with sharp, firm objects like a toothpick or a pen, as that can damage your throat or tonsils.
• If your tonsils are inflamed, swollen, or infected, your doctor may prescribe antibiotics or anti-inflammatory medications.

Is surgery ever necessary?

Occasionally, surgery may be warranted. It’s generally reserved for people with severe symptoms or frequent infections who don’t improve with the measures mentioned above.

Surgical options are:

• tonsillectomy, which is removing the tonsils
• cryptolysis, which uses laser, electrical current, or radio waves to smooth the deep indentations in tonsils that allow stones to form.

Can tonsil stones be prevented?

Yes, there are ways to reduce the risk that tonsil stones will recur. Experts recommend the following:

• Brush your teeth and tongue regularly (at least twice a day: in the morning and before sleep).
• Floss regularly.
• Gargle with salt water after eating.
• Eliminate foods and drinks that contain a lot of sugar, which feeds bacteria that can help stones form.
• Don’t smoke, because smoking irritates and inflames tonsils, which can encourage stone formation. The same may apply to vaping, though there is limited research to rely upon.

The bottom line

Considering how common tonsil stones are and how bothersome they can be, it seems strange that they aren’t more well known. Maybe that’s because they often get better on their own, or people figure out how to deal with them without needing medical attention.

I hope you aren’t one of the many millions of people bothered by tonsil stones. But if you are, it’s good to know that they’re generally harmless and can be readily treated and prevented.

Now that you know more about them, feel free to spread the word: tonsil stones should be a secret no more.

It’s an unfortunate reality: all medicines can cause side effects. While there are a few tried-and-true ways to deal with drug side effects, here’s a less common option to consider: adding a second medication.

That’s the approach taken with valbenazine (Ingrezza), a drug approved for a condition called tardive dyskinesia that’s caused by certain medicines, most of which are for mental health. Let’s dive into what TD is, how this drug is advertised, and what else to consider if a medicine you take causes TD.

What is tardive dyskinesia?

Tardive dyskinesia (TD) is a condition marked by involuntary movements of the face or limbs, such as rapid eye blinking, grimacing, or pushing out the tongue. TD is caused by long-term use of certain drugs, many of which treat psychosis.

TD may be irreversible. Early recognition is key to improvement and preventing symptoms from getting worse. If you take antipsychotic medicines or other drugs that can cause TD, tell your prescribing health care provider right away about any worrisome symptoms.

A sidewalk sale, a cookout in the park, and a pitch

One ad for Ingrezza starts with a young man working with customers at a sidewalk sale. Though his mental health is much better, he says, now he’s suffering with TD, a condition “that can be caused by some mental health meds.” A spotlight shines on his hands as he fumbles and drops an instant camera he’s selling. He seems embarrassed and his customers look perplexed.

Next we see a young woman at a cookout in a park. The mysterious spotlight is trained on her face as she blinks and grimaces involuntarily. Her voiceover explains that she feels like her involuntary movements are “always in the spotlight.”

Later these two happily interact with others, their movement problems much improved. A voiceover tells us Ingrezza is the #1 treatment for adults with TD. The dose — “always one pill, once a day” — can improve unwanted movements in seven out of 10 people. And people taking Ingrezza can stay on most mental health meds.

That’s the pitch. The downsides come next.

What are the side effects of this drug to control a side effect?

As required by the FDA, the ad lists common and serious side effects of Ingrezza, including

• sleepiness (the most common side effect)
• depression, suicidal thoughts, or actions
• heart rhythm problems
• allergic reactions, which can be life-threatening
• fevers, stiff muscles, or problems thinking, which may be life threatening
• abnormal movements.

That’s right, one possible side effect is abnormal movements — a symptom this drug is supposed to treat!

What the ad gets right

The ad

• appropriately highlights TD as a troubling yet treatable condition that can cause stress and embarrassment and affect a person’s ability to function
• emphasizes once-daily dosing, presumably because the recommended frequency of a competitor’s drug for TD is twice daily
• shares clinical studies that support effectiveness claims
• covers many of the most common and serious side effects.

What else should you know?

Unfortunately, the ad skims over — or entirely skips — some important details. Below are a few examples.

Which medicines cause TD?

We never learn which medicines can cause TD (especially when used long-term), which seems vital to know. Many, but not all, are used to help treat certain mental health disorders, such as schizophrenia or bipolar disorder. Here are some of the most common.

Mental health medicines:

• haloperidol (Haldol)
• fluphenazine (Prolixin)
• risperidone (Risperdal)
• olanzapine (Zyprexa).

Other types of medicines:

• metoclopramide (Reglan), which may be prescribed for nausea, hiccups, and a stomach problem called gastroparesis
• prochlorperazine (Compazine, Compro), most often prescribed for severe nausea, migraine headaches, or vertigo.

Also, the ad never explains that TD may be irreversible regardless of treatment. Because improvement is most likely if caught early, it’s important for people taking these medicines to check in with their health provider if they notice TD symptoms described above — especially if symptoms are growing worse.

What about effectiveness and cost?

Seven in 10 people reported that their symptoms improved, according to the ad. How much improvement? That wasn’t shared. But here’s what I found in a key study:

• Among 202 study participants with TD, only 24% reported having minimal or no symptoms of TD after six weeks of treatment with Ingrezza.
• Up to 67% of study subjects reported smaller improvements in symptoms.

What happens after six weeks? A few small follow-up studies suggest that some people who continue taking Ingrezza may improve further over time.

And the cost? That’s also never mentioned in the ad. It’s about $8,700 a month. No details on the financial assistance program, or who qualifies for free treatment, are provided.

Are there other ways to manage TD?

Well, yes. But the ad doesn’t mention those either. Three approaches to discuss with your healthcare provider are:

• Avoid drugs known to cause TD when other options are available.
• If you need to take these medicines, it’s safest to use the lowest effective dose for the shortest time possible. For example, limiting metoclopramide to less than three months lowers risk for TD.
• If you notice TD symptoms, ask about lowering the dose or stopping the offending drug right away. This may successfully reverse, or reduce, the symptoms.

If you have TD, you and your health care provider can consider several options:

• whether other drug treatments for TD not mentioned in the ad, such as deutetrabenazine (Austedo) or tetrabenazine (Xenazine), might cost less or minimize bothersome side effects
• botulinum toxin injections (Botox), which can relax the muscle contractions causing involuntary movements
• deep brain stimulation, which involves electrical stimulation to certain areas of the brain to interrupt nerve signals to abnormally contracting muscles.

The bottom line

The idea of treating a drug’s side effect with another drug may not be appealing. Certainly, it makes sense to try other options first.

But sometimes there are no better options. It’s always worth asking whether a treatment is worse than the disease. But TD is one situation in which all options — including a drug treatment for another drug’s side effects — are well worth considering.

Trouble staying focused and paying attention are two familiar symptoms of attention deficit hyperactivity disorder (ADHD), a common health issue among children and teens.

When ADHD persists through early adulthood and on into middle age, it presents many of the same challenges it does in childhood: it’s hard to stay organized, start projects, stay on task, and meet deadlines. But now life is busier, and often expectations from work and family are even higher. Fortunately, there are lots of strategies that can help you navigate this time in your life.

Staying organized

Organizational tools are a must for people with adult ADHD. They’ll help you prioritize and track activities for each day or the coming weeks.

• Pick the right tools. Tools can include a pen and paper to make lists, or computer or smartphone apps to set appointment reminders, highlight important days on the calendar, mark deadlines, and keep lists and other information handy.
• Schedule updates. Set aside time each day to update your lists and schedules. Don’t let the task become a chore in itself; think of it like a routine task such as brushing your teeth, and do it daily so it becomes an established habit.
• Set a timer. And a word of caution: smartphones and computers can also turn into a distraction. If you have adult ADHD, you may find yourself spending hours looking at less useful apps or sites. If that’s a frequent trap for you, set a timer for each use or keep the phone off or in another room when you are trying to work.

Staying focused

Just being organized doesn’t mean your work will get done. But a few simple approaches can at least make it easier to do the work.

• Declutter your home and office. Give yourself an appealing work environment and keep important items easily accessible.
• Reduce distractions. This could mean changing your workstation so it doesn’t face a window, moving to a quieter space, or just silencing your smartphone and email alerts.
• Jot down ideas as they come to you. You may have an “aha” moment for one task while you’re in the middle of another. That’s okay; just write down that thought and get back to it later, after your more pressing work is finished.

Meeting deadlines

Deadlines pose two big challenges when you have adult ADHD. First, it’s hard to start a project, often because you want it to be perfect, or you’re intimidated by it so you put it off. Second, when you do start a project, it’s very easy to become distracted and leave the task unfinished.

How can you avoid these traps?

• Put off procrastinating. Put procrastination on your to-do list — like a chore — and fool yourself into actually starting your work.
• Deal with emails, phone calls, or other matters as soon as you can. That way there will be fewer things hanging over your head and overwhelming you later on.
• Be a clock watcher. Get a watch and get in the habit of using it. The more aware you are of time, the more likely you’ll be able to avoid spending too long on a task.
• Take one thing at a time. Multitasking is overrated for everyone — and it’s a nightmare for people with adult ADHD. Focus on completing one task, then move on to the next.
• Be realistic about your time. This can mean having to say no to new projects or other commitments.

Get more help

The ideas listed here can help you start coping with adult ADHD, but they may not be enough to help you overcome adult ADHD’s challenges.

Consider hiring an ADHD coach who can provide more strategies and give you additional tools to cope with your condition. Look for an ADHD coach who is a licensed mental health professional who specializes in treating ADHD, and may also have a certification in ADHD coaching from the ADHD Coaches Organization.

When you live in a coastal area, preparing early for potential hurricanes is a must. Storms can develop quickly, leaving little time to figure out where you’ll be safe or which items to pack if you have to evacuate. And health care necessities, such as medications or medical equipment, are often overlooked in the scramble.

“People might bring their diabetes medication but forget their blood sugar monitor, or bring their hearing aids but forget extra batteries for them,” says Dr. Scott Goldberg, medical director of emergency preparedness at Brigham and Women’s Hospital and a longtime member of a FEMA task force that responds to hurricane-damaged areas.

Here’s some insight on what to expect this hurricane season, and how to prioritize health care in your hurricane kit.

What will the 2024 hurricane season look like?

This year’s hurricane predictions underscore the urgency to start preparations now.

Forecasters with the National Oceanic and Atmospheric Administration's National Weather Service expect above-normal activity for the 2024 hurricane season (which lasts until November 30).

Meteorologists anticipate 17 to 25 storms with winds of 39 mph or higher, including eight to 13 hurricanes — four to seven of which could be major hurricanes with 111 mph winds or higher.

What kinds of plans should you make?

Preparing for the possibility of big storms is a major undertaking. Long before ferocious winds and torrential rains arrive, you must gather hurricane supplies, figure out how to secure your home, and determine where to go if you need to evacuate (especially if you live in a flood zone). Contact the emergency management department at your city or county for shelter information.

If you’ll need help evacuating due to a medical condition, or if you’ll need medical assistance at a shelter, find out if your county or city has a special needs registry like this one in Florida. Signing up will enable first responders to notify you about storms and transport you to a special shelter that has medical staff, hospital cots, and possibly oxygen tanks.

What should you pack?

While a shelter provides a safe place to ride out a storm, including bathrooms, water, and basic meals, it’s up to you to bring everything else. It’s essential to pack medical equipment and sufficient medications and health supplies.

“It’s natural to just grab the prescription medications in your medicine cabinet, but what if it’s only a two-day supply? It might be a while before you can get a refill. We recommend at least a 14-day or 30-day supply of every prescription,” Dr. Goldberg says. “Talk to your doctor about the possibility of getting an extra refill to keep on standby for your go bag.”

Other health-related items you’ll want to pack include:

• medical supplies you use regularly, such as a blood pressure monitor, heart monitor, CPAP machine, wheelchair, or walker
• over-the-counter medicines you use regularly, such as heartburn medicine or pain relievers
• foods for specific dietary needs, such as gluten-free food if you have celiac disease (if you have infants or children, you’ll need to bring foods they can eat)
• healthy, nonperishable snacks such as nuts, nut butters, trail mix, dried fruit, granola bars, protein bars, and whole-grain bread, crackers, or cereals
• hygiene products such as soap, hand sanitizer, toothbrushes and toothpaste, shampoo, deodorant, infant or adult diapers, lip balm, moist towelettes, and toilet paper — because shelters often run out of it.

Remember the basics

In some ways, you can think of shelter living like camping. You’ll need lots of basic supplies to get through it, including:

• a sleeping bag or blanket and pillow for each person in your family
• clean towels and washcloths
• a few extra changes of clothes per person
• a first-aid kit
• flashlights and extra batteries
• chargers for your electronic gadgets
• rechargeable battery packs.

Bring important paperwork

In addition to supplies, bring important documents such as:

• a list of your medications, vitamins, and supplements (include the name, dose, and frequency of each one)
• a list of the names, addresses, and phone numbers of your primary care provider and any specialists who treat you
• a list of your emergency contacts and their phone numbers
• your pharmacy’s phone number and address
• copies of your birth certificate and driver’s license
• copies of home, car, or life insurance policies
• copies of your health insurance cards
• a copy of your advance directive — which includes your living will and health care proxy form.

“Store these documents on a flash drive. Also make photocopies of them, which are easiest for doctors to consult in an emergency setting. Place them in a plastic zip-top bag to keep them dry,” Dr. Goldberg advises.

Prepare right now

Start today. Gather as many go-bag supplies as you can, including the bags. A small suitcase, backpack, or duffel bag for each person in your family will work well.

And try not to put off these important preparations. “Hurricanes are major stressors. You might be worried, sleep deprived, fatigued, and emotional,” Dr. Goldberg says. “All of that will make it hard to think clearly. You’ll do yourself and your family a favor by having discussions now and getting started on your hurricane plan.”

Not so long ago, a friend texted me from a coffee shop. He said, "I can't believe it. I'm the only one here without a tattoo!" That might not seem surprising: a quick glance around practically anywhere people gather shows that tattoos are widely popular.

Nearly one-third of adults in the US have a tattoo, according to a Pew Research Center survey, including more than half of women ages 18 to 49. These numbers have increased dramatically over the last 20 years: around 21% of US adults in 2012 and 16% of adults in 2003 reported having at least one tattoo.

If you're among them, some recent headlines may have you worried:

              Study Finds That Tattoos Can Increase Your Risk of Lymphoma (OnlyMyHealth)

              Getting a Tattoo Puts You At Higher Risk of Cancer, Claims Study (NDTV)

              Inky waters: Tattoos increase risk of lymphoma by over 20%, study says (Local12.com)

              Shocking study reveals tattoos may increase risk of lymphoma by 20% (Fox News)

What study are they talking about? And how concerned should you be? Let's go through it together. One thing is clear: there's much more to this story than the headlines.

Why are researchers studying a possible link between tattoos and lymphoma?

Lymphoma is a type of cancer that starts in the lymphatic system, a network of vessels and lymph nodes that twines throughout the body. With about 90,000 newly diagnosed cases a year, lymphoma is one of the most common types of cancer.

Risk factors for it include:

• advancing age
• certain infections (such as Epstein-Barr virus, HIV, and hepatitis C)
• exposure to certain chemicals (such as benzene, or possibly pesticides)
• family history of lymphoma
• exposure to radiation (such as nuclear reactor accidents or after radiation therapy)
• having an impaired immune system
• certain immune diseases (such as rheumatoid arthritis, Sjogren's disease, or celiac disease).

Tattoos are not known to be a cause or risk factor for lymphoma. But there are several reasons to wonder if there might be a connection:

• Ink injected under the skin to create a tattoo contains several chemicals classified as carcinogenic (cancer causing).
• Pigment from tattoo ink can be found in enlarged lymph nodes within weeks of getting a tattoo.
• Immune cells in the skin can react to the chemicals in tattoo ink and travel to nearby lymph nodes, triggering a bodywide immune reaction.
• Other triggers of lymphoma, such as pesticides, have a similar effect on immune cells in lymph nodes.

Is there a connection between tattoos and lymphoma?

Any potential connection between tattoos and lymphoma has not been well studied. I could find only two published studies exploring the possibility, and neither found evidence of a compelling link.

The first study compared 737 people with the most common type of lymphoma (called non-Hodgkin's lymphoma) with otherwise similar people who did not have lymphoma. The researchers found no significant difference in the frequency of tattoos between the two groups.

A study published in May 2024 — the one that triggered the scary headlines above — was larger. It compared 1,398 people ages 20 to 60 who had lymphoma with 4,193 people who did not have lymphoma but who were otherwise similar. The study found that

• lymphoma was 21% more common among those with tattoos
• lymphoma risk varied depending on how much time had passed since getting the tattoo:
  • within two years, lymphoma risk was 81% higher
  • between three and 10 years, no definite increased lymphoma risk was detected
  • 11 or more years after getting a tattoo, lymphoma risk was 19%

There was no correlation between the size or number of tattoos and lymphoma risk.

What else should you know about the study?

Importantly, nearly all of the differences in rates of lymphoma between people with and without tattoos were not statistically significant. That means the reported link between lymphoma and tattoos is questionable — and quite possibly observed by chance. In fact, some of the other findings argue against a connection, such as the lack of a link between size or number of tattoos and lymphoma risk.

In addition, if tattoos significantly increase a person's risk of developing lymphoma, we might expect lymphoma rates in the US to be rising along with the popularity of tattoos. Yet that's not the case.

Finally, a study like this one (called an association study) cannot prove that a potential trigger of disease (in this case, tattoos) actually caused the disease (lymphoma). There may be other factors (called confounders) that are more common among people who have tattoos, and those factors might account for the higher lymphoma risk.

Do tattoos come with other health risks?

While complication rates from reputable and appropriately certified tattooists are low, there are health risks associated with tattoos:

• infection, including bacterial skin infections or viral hepatitis
• allergic reactions to the ink
• scarring
• rarely, skin cancer (melanoma and other types of skin cancer).

The bottom line

Despite headlines suggesting a link between tattoos and the risk of lymphoma, there's no convincing evidence it's true. We'll need significantly more research to say much more than that. In the meantime, there are more important health concerns to worry about and much better ways for all of us to reduce cancer risk.

Don’t worry. It’s good advice if you can take it. Of course that’s not always easy, especially for health concerns.

The truth is: it’s impossible (and ill-advised) to never worry about your health. But are you worrying about the right things? Let’s compare a sampling of common worries to the most common conditions that actually shorten lives. Then we can think about preventing the biggest health threats.

Dangerous but rare health threats

The comedian John Mulaney says the cartoons he watched as a child gave him the impression that quicksand, anvils falling from the sky, and lit sticks of dynamite represented major health risks. For him (as is true for most of us), none of these turned out to be worth worrying about.

While harm can befall us in many ways, some of our worries are not very likely to occur:

• Harm by lightning: In the US, lightning strikes kill about 25 people each year. Annually, the risk for the average person less than one in a million. There are also several hundred injuries due to nonfatal lightning strikes. Even though lightning strikes the earth millions of times each year, the chances you’ll be struck are quite low.
• Dying in a plane crash: The yearly risk of being killed in a plane crash for the average American is about one in 11 million. Of course, the risk is even lower if you never fly, and higher if you regularly fly on small planes in bad weather with inexperienced pilots. By comparison, the average yearly risk of dying in a car accident is approximately 1 in 5,000.
• Snakebite injuries and deaths: According to the Centers for Disease Control and Prevention, an estimated 7,000 to 8,000 people are bit by poisonous snakes each year in the US. Lasting injuries are uncommon, and deaths are quite rare (about five per year). In parts of the country where no poisonous snakes live, the risk is essentially zero.
• Shark attacks: As long as people aren’t initiating contact with sharks, attacks are fairly uncommon. Worldwide, about 70 unprovoked shark attacks occur in an average year, six of which are fatal. In 2022, 41 attacks occurred in the US, two of which were fatal.
• Public toilet seats: They may appear unclean (or even filthy), but they pose little or no health risk to the average person. While it’s reasonable to clean off the seat and line it with paper before touching down, health fears should not discourage you from using a public toilet.

I’m not suggesting that these pose no danger, especially if you’re in situations of increased risk. If you’re on a beach where sharks have been sighted and seals are nearby, it’s best not to swim there. When in doubt, it’s a good idea to apply common sense and err on the side of safety.

What do Google and TikTok tell us about health concerns?

Analyzing online search topics can tell us a lot about our health worries.

The top Google health searches in 2023 were:

• How long is strep throat contagious?
• How contagious is strep throat?
• How to lower cholesterol?
• What helps with bloating?
• What causes low blood pressure?

Really? Cancer, heart disease and stroke, or COVID didn’t reach the top five? High blood pressure didn’t make the list, but low blood pressure did?

Meanwhile, on TikTok the most common topics searched were exercise, diet, and sexual health, according to one study. Again, no top-of-the-list searches on the most common and deadly diseases.

How do our worries compare with the top causes of death?

In the US, these five conditions took the greatest number of lives in 2022:

• heart disease
• cancer
• unintentional injury (including motor vehicle accidents, drug overdoses, and falls)
• COVID-19
• stroke.

This list varies by age. For example, guns are the leading cause of death among children and teenagers (ages 1 to 19). For older teens (ages 15 to 19), the top three causes of death were accidents, homicide, and suicide.

Perhaps the lack of overlap between leading causes of death and most common online health-related searches isn’t surprising. Younger folks drive more searches and may not have heart disease, cancer, or stroke at top of mind. In addition, online searches might reflect day-to-day concerns (how soon can my child return to school after having strep throat?) rather than long-term conditions, such as heart disease or cancer. And death may not be the most immediate health outcome of interest.

But the disconnect suggests to me that we may be worrying about the wrong things — and focusing too little on the biggest health threats.

Transforming worry into action

Most of us can safely worry less about catching something from a toilet seat or shark attacks. Instead, take steps to reduce the risks you face from our biggest health threats. Chipping away at these five goals could help you live longer and better while easing unnecessary worry:

• Choose a heart-healthy diet.
• Get routinely recommended health care, including blood pressure checks and cancer screens, such as screening for colorectal cancer.
• Drive more safely. Obey the speed limit, drive defensively, always wear a seatbelt, and don’t drive if you’ve been drinking.
• Don’t smoke. If you need to quit, find help.
• Get regular exercise.

The bottom line

Try not to focus too much on health risks that are unlikely to affect you. Instead, think about common causes of poor health. Then take measures to reduce your risk. Moving more and adding healthy foods to your meals is a great start.

And in case you’re curious, the average number of annual deaths due to quicksand is zero in the US. Still a bit worried? Fine, here’s a video that shows you how to save yourself from quicksand even though you’ll almost certainly never need it.
