The daily bath or shower is a routine for many of us — and for our children, too. But is it really necessary?

The short answer is no.

Obviously, there are days when washing up makes good sense — like if your child is grimy from a day in the dirt; covered in sweat, paint, or other visible dirt; or had an explosive poop. It’s also a good idea to wash up if your child has spent the day in a pool (the chlorine may be irritating to the skin), a body of water (there could be things in the water that are irritating or unhealthy), or used bug spray to ward off ticks and mosquitoes. And certainly, it’s best for everyone in the vicinity when a stinky teenager takes a soapy shower.

Sometimes a doctor may recommend daily bathing for certain skin conditions. And we all need to wash our hands regularly to prevent infection. But full-body washing just for the sake of washing? Not so much.

Why not bathe a child daily?

Lots of bathing can lead to dry, irritated skin. But also, the skin has natural protective oils, and natural bacteria, that help to keep us healthy and safe — and that can get washed away with daily bathing.

If your baby or preteen looks pretty clean, isn’t stinky, isn’t covered in bug spray, and hasn’t been in a pool or other body of water, it’s fine to skip the bath or shower. Really, bathing two or three times a week is fine. In fact, for many kids, even just once or twice a week is fine. You can always do a quick wipe with a wet washcloth to the face, groin area, and any dirty spots.

Stinky teenagers might need more bathing or showering, depending on activity level and deodorant use. But even they may be able to get away with washing their face and using a soapy washcloth on their groin and underarms.

Tips for healthy bathing

When you do bathe children, here are some tips for healthy bathing.

• Don’t use hot water — use warm water instead.
• Keep it short — preferably just enough time to get the washing done.
• Avoid antibacterial soaps and bubble baths. Use mild, unscented soap and shampoo.
• Make sure bathing is supervised for all babies and young children.
• Pat dry rather than rubbing dry. If your child tends to have dry skin, using a mild, unscented greasy moisturizer after the bath can be helpful.

If your child has eczema or any other skin condition, check with your doctor to get tailored advice for bathing your child.

Over the course of a lifetime, as many as seven in 10 adults in the United States will directly experience or witness harrowing events. These include gun violence, car accidents, and other personal trauma; natural or human-made disasters, such as Hurricane Katrina and the 9/11 terrorist attacks; and military combat. And some — though not all — will experience post-traumatic stress disorder, or PTSD.

New guidelines released in 2024 can help guide effective treatment.

What is PTSD?

PTSD is a potentially debilitating mental health condition. It’s marked by recurrent, frightening episodes during which a person relives a traumatic event.

After a disturbing event, it’s normal to have upsetting memories, feel on edge, and have trouble sleeping. For most people, these symptoms fade over time. But when certain symptoms persist for more than a month, a person may be experiencing PTSD.

These symptoms include

• recurring nightmares or intrusive thoughts about the event
• feeling emotionally numb and disconnected
• withdrawing from people and certain situations
• being jumpy and on guard.

The National Center for PTSD offers a brief self-screening test online, which can help you decide whether to seek more information and help.

Who is more likely to experience PTSD?

Not everyone who experiences violence, disasters, and other upsetting events goes on to develop PTSD. However, military personnel exposed to combat in a war zone are especially vulnerable. About 11% to 20% of veterans who served in Iraq or Afghanistan have PTSD, according to the National Center for PTSD.

What about people who were not in the military? Within the general population, estimates suggest PTSD occurs in 4% of men and 8% of women — a difference at least partly related to the fact that women are more likely to experience sexual assault.

What are the new guidelines for PTSD treatment?

Experts from the U.S. Department of Veterans Affairs and Department of Defense collaborated on new guidelines for treating PTSD. They detailed the evidence both for and against specific therapies for PTSD.

Their findings apply to civilian and military personnel alike, says Dr. Sofia Matta, a psychiatrist at Harvard-affiliated Massachusetts General Hospital and senior director of medical services at Home Base, a nonprofit organization that provides care for veterans, service members, and their families.

The circle of care is widely drawn for good reason. “It’s important to recognize that PTSD doesn’t just affect the person who is suffering but also their families and sometimes, their entire community,” Dr. Matta says. The rise in mass shootings in public places and the aftermath of these events are a grim reminder of this reality, she adds.

Which treatment approaches are most effective for PTSD?

The new guidelines looked at psychotherapy, medications, nondrug therapies. Psychotherapy, sometimes paired with certain medicines, emerged as the most effective approach.

The experts also recommended not taking certain drugs due to lack of evidence or possible harm.

Which psychotherapies are recommended for PTSD?

The recommended treatment for PTSD, psychotherapy, is more effective than medication. It also has fewer adverse side effects and people prefer it, according to the guidelines.

Which type of psychotherapy can help? Importantly, the most effective therapies for people with PTSD differ from those for people with other mental health issues, says Dr. Matta.

Both cognitive processing therapy and prolonged exposure therapy were effective. These two therapies teach people how to evaluate and reframe the upsetting thoughts stemming from the traumatic experience. The guidelines also recommend mindfulness-based stress reduction, an eight-week program that includes meditation, body scanning, and simple yoga stretches.

Which medications are recommended for PTSD?

Some people with severe symptoms need medication to feel well enough to participate in therapy. “People with PTSD often don’t sleep well due to insomnia and nightmares, and the resulting fatigue makes it hard to pay attention and concentrate,” says Dr. Matta.

Three medicines commonly prescribed for depression and anxiety — paroxetine (Paxil), sertraline (Zoloft), and venlafaxine (Effexor) — are recommended. Prazosin (Minipress) may help people with nightmares, but the evidence is weak.

Which medications are not recommended for PTSD?

The guidelines strongly recommended not taking benzodiazepines (anti-anxiety drugs often taken for sleep). Benzodiazepines such as alprazolam (Xanax) and clonazepam (Klonopin) offer no proven benefits for people with PTSD. They have several potential harms, including negative cognitive changes and decreased effectiveness of PTSD psychotherapies.

What about cannabis, psychedelics, and brain stimulation therapies?

Right now, evidence doesn’t support the idea that cannabis helps ease PTSD symptoms. And there are possible serious side effects from the drug, such as cannabis hyperemesis syndrome (severe vomiting related to long-term cannabis use).

There isn’t enough evidence to recommend for or against psychedelic-assisted therapies such as psilocybin (magic mushrooms) and MDMA (ecstasy). “Because these potential therapies are illegal under federal law, the barriers for conducting research on them are very high,” says Dr. Matta. However, recent legislative reforms may make such studies more feasible.

Likewise, the evidence is mixed for a wide range of other nondrug therapies, such as brain stimulation therapies like repetitive transcranial magnetic stimulation or transcranial direct current stimulation.

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.

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.”

Concussion is one of the most common injuries to the brain, affecting about two million children and teens every year. It is a particular kind of injury that happens when a blow to the head or somewhere else on the body makes the brain move back and forth within the skull.

It’s possible to get a concussion after what might seem like a minor injury, like a forceful push from behind, or a collision between two players in a football or soccer game.

What are the signs and symptoms of concussion?

Because the injury may not seem that significant from the outside, it’s important to know the symptoms of a concussion. There are many different possible symptoms, including

• passing out (this could be a sign of a more serious brain injury)
• headache
• dizziness
• changes in vision
• feeling bothered by light or noise
• confusion or feeling disoriented
• memory problems (such as difficulty remembering details of the injury) or difficulty concentrating
• balance or coordination problems
• mood changes.

Some of these are visible to others and some are felt by the person with the concussion. That’s why it’s important to know the signs and to ask all the right questions of a child who has had an injury.

Sometimes the symptoms might not be apparent right away, but show up in the days following the injury. The CDC’s Heads Up website has lots of great information about how to recognize a concussion.

How can further harm to the brain be avoided?

The main reason it’s important to recognize a possible concussion early is that the worst thing you can do after getting a concussion is get another one. The brain is vulnerable after a concussion; if it is injured again, the symptoms can be longer lasting — or even permanent, as in cases of chronic traumatic encephalopathy (CTE), a condition that has been seen in football players and others who have repeated head injuries.

If there is a chance that a child has had a concussion during a sports competition, they must stop playing — and get medical attention. It’s important to get medical attention any time there is concern about a possible concussion, both to be sure there isn’t a more serious brain injury, and to do a good assessment of the symptoms, so that they can be monitored over time. There are some screening questionnaires that are used by doctors that can be used again in the days and weeks after the concussion to see how the child is improving.

What helps children recover after a concussion?

Experts have struggled with figuring out how to protect the brain after a concussion. For a long time, the recommendation was to rest and do very little at all. This meant not doing any exercise, not going to school, not even reading or watching television. As symptoms improved, the restrictions were lifted gradually.

Over time, though, research showed that not only was this much rest not necessary, it was counterproductive. It turns out that getting kids back into their daily lives, and back into being active, is safe and leads to quicker recovery. Experts still recommend rest and then moving gradually back into activities, but the guidelines are no longer as strict as they once were.

One important note: A medical professional should guide decisions to move from rest to light activity, and then gradually from there to moderate and then regular activities based on how the child is doing. This step-by-step process may extend for days, weeks, or longer, depending on what the child needs. Parents, coaches, and schools can help support a child or teen as they return to school and return to activities and sports.

Some children will be able to get back into regular activities quickly. But for others it can take weeks or even months. Schools and sports trainers should work with children to support them in their recovery. Some children develop post-concussive syndromes with headache, fatigue, and other symptoms. This is rare but can be very disabling.

How can parents help prevent concussions?

It's not always possible to prevent concussions, but there are things that parents can do:

• Be sure that children use seat belts and other appropriate restraints in the car.
• Have clear safety rules and supervise children when they are playing, especially if they are riding bikes or climbing in trees or on play structures.
• Since at least half of concussions happen during sports, it’s important that teams and coaches follow safety rules. Coaches should teach techniques and skills to avoid dangerous collisions and other injuries. Talk to your child’s coaches about what they are doing to keep players safe. While helmets can prevent many head injuries, they don’t prevent concussions.

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.

It’s easy to say you simply don’t have time to be mindful. With so much going on in daily life, who has time to stop and be present? But everyone has at least 10 minutes to spare to practice mindfulness.

The point of these brief, daily reflections is to help you tap into calmness whenever life gets too hairy. Practicing everyday mindfulness can also improve your memory and concentration skills and help you feel less distracted and better able to manage stress . And mindfulness tools have been successfully incorporated into treatments for anxiety and depression.

There is more than one way to practice mindfulness. Still, any mindfulness technique aims to achieve a state of alert, focused, relaxed consciousness by deliberately paying attention to thoughts and sensations without passing judgment on them. This allows the mind to focus on the present moment with an attitude of acceptance.

Three easy mindfulness exercises to try

Here are three simple exercises you can try whenever you need a mental break, emotional lift, or just want to pause and appreciate everything around you. Devote 10 minutes a day to them and see how the experience changes your outlook. It’s time well spent.

Simple meditation

A quick and easy meditation is an excellent place to begin practicing mindfulness.

• Sit on a straight-backed chair or cross-legged on the floor.
• Focus on an aspect of your breathing, such as the sensations of air flowing into your nostrils and out of your mouth, or your belly rising and falling as you inhale and exhale.
• Once you’ve narrowed your concentration in this way, begin to widen your focus. Become aware of sounds, sensations, and ideas. Embrace and consider each without judgment.
• If your mind starts to race, return your focus to your breathing. Then expand your awareness again.
• Take as much time as you like: one minute, or five, or 10 — whatever you’re comfortable with. Experts in mindfulness meditation note that the practice is most helpful if you commit to a regular meditation schedule.

Open awareness

Another approach to mindfulness is “open awareness,” which helps you stay in the present and truly participate in specific moments in life. You can choose any task or moment to practice open awareness, such as eating, taking a walk, showering, cooking a meal, or working in the garden. When you are engaged in these and other similar routine activities, follow these steps.

• Bring your attention to the sensations in your body, both physical and emotional.
• Breathe in through your nose, allowing the air to fill your lungs. Let your abdomen expand fully. Then breathe out slowly through your mouth.
• Carry on with the task at hand, slowly and with deliberation.
• Engage each of your senses, paying close attention to what you can see, hear, feel, smell, and taste.
• Try “single-tasking,” bringing your attention as fully as possible to what you’re doing.
• Allow any thoughts or emotions that arise to come and go, like clouds passing through the sky.
• If your mind wanders away from your current task, gently refocus your attention back to the sensation of the moment.

Body awareness

Another way to practice mindfulness is to focus your attention on other thoughts, objects, and sensations. While sitting quietly with your eyes closed, channel your awareness toward each of the following:

• Sensations: Notice subtle feelings such as an itch or tingling without judgment, and let them pass. Notice each part of your body in succession from head to toe.
• Sights and sounds: Notice sights, sounds, smells, tastes, and touches. Name them “sight,” “sound,” “smell,” “taste,” or “touch” without judgment and let them go.
• Emotions: Allow emotions to be present without judging them. Practice a steady and relaxed naming of emotions: “joy,” “anger,” “frustration.”
• Urges: When you feel a craving or an urge (for instance, to eat excess food or practice an unwanted behavior), acknowledge the desire and understand that it will pass. Notice how your body feels as the craving enters. Replace the wish for the craving to go away with the specific knowledge that it will subside.
