While its most classic symptom is gut pain, celiac disease also can disrupt mental, psychosocial, and nutritional health. Learn how to manage it here.

When many people think of celiac disease, they tend to focus their attention on their “gut feelings.” But the gastrointestinal immune disorder’s ripple effect can also be felt in your brain, nutrition, and psychosocial health, as well.

In fact, 89% of people with celiac disease suffer from brain fog, a spectrum disorder that includes forgetfulness, mental fatigue and confusion. More than half of patients feel socially isolated. And many experience the signs of malnutrition.

Learn the difference between celiac disease and gluten sensitivities.

With an estimated 3 million people suffering from celiac disease, the condition has attracted legislative attention. In May, U.S. lawmakers introduced the Celiac Safety Act, which would amend the Federal Food, Drug, and Cosmetic Act to require all gluten-containing grains be classified and labeled as major food allergens.

Considering that up to 83% of people with celiac disease might be misdiagnosed or undiagnosed, according to the nonprofit group Beyond Celiac, the legislation may reduce unnecessary illness and complications. The Celiac Disease Foundation is raising awareness, and we are, too. Following is how celiac disease can compromise your overall mental, social, and dietary health.

Understanding Celiac Disease and Why It Occurs

The culprit behind celiac disease is gluten, a protein found in all grains including wheat, barley, and rye.

Gluten is a source of plant protein that the body’s enzymes cannot completely break down. For most people this is not a problem, and the undigested gluten passes through the small intestine fine.

But in an estimated one in 100 people, the body’s immune system identifies the protein as harmful and attacks it. This autoimmune response damages the threadlike projections, called villi, that line the small intestine and absorb nutrients, leading to inflammation and potential nutrition deficiency.

The following symptoms should alert you to the disease:

• Fatigue and/or headaches
• Diarrhea or constipation
• Gas and bloating
• Abdominal pain, nausea, and vomiting
• Bone and joint pain
• Blistery, itchy skin rashes
• Weight loss

Also, if you have a close family member with celiac disease, you are at greater risk of developing it – about one in 10.

How Celiac Disease Affects Your Brain

As the symptoms above point out, fatigue is a classic sign of celiac disease, but it is just one in a spectrum of characteristics that describe brain fog, a neurocognitive impairment. Other aspects of brain fog include forgetfulness, trouble concentrating, grogginess, mental confusion, and detachment.

Additionally, celiac disease has been linked to panic attacks, depression, irritability, and obsessive-compulsive tendencies.

The link between these disorders exists in a channel called gut-brain axis, through which the neurons in the gastrointestinal tract and brain communicate and respond accordingly.

For example, if you think about eating lunch, your stomach will release fluids to prepare for digestion. Alternately, if your body is unable to absorb important nutrients due to celiac disease, your brain might not be able to produce enough serotonin, dopamine, and other neurotransmitters to regulate mood and emotion.

Further, the body’s immune response to celiac disease – sending antibodies to attack its own tissue – might produce stress hormones and low blood flow to the brain.

If your brain suffers, other aspects of your life will likely suffer. This includes your social life.

How Celiac Disease Affects Your Psychosocial Health

Because patients with celiac disease dread the symptoms, they tend to live in smaller worlds, tightening their social “footprint” to familiar locations and manageable timeframes.

Celiac patients wrestle with anxiety about telling others of the condition and expressing their needs, which can contribute to social separation. Even ordering food in a restaurant can trigger stress about being “difficult.”

And then there’s the near-constant worry of unintentionally eating gluten.

Indeed, 54% of people with celiac disease or gluten sensitivity said they feel isolated or excluded in social settings, according to a 2025 study by Beyond Celiac. Two-thirds of people avoid social gatherings and parties. More than half skip visits to share meals with family and friends.

In short, living with celiac can be lonely, and this can cause anxiety and depression.

How Celiac Disease Affects Nutrition

Because the immune systems of people with celiac disease attack and damages the villi in the small intestine, patients tend to suffer from poor nutrient absorption (malabsorption).

It doesn’t matter how much food these patients eat; their intestinal lining is unable to absorb iron, vitamins, and other essential nutrients. In time, malabsorption can lead to anemia (from iron deficiency), bone loss (calcium deficiency), muscle loss, and infertility.

Further, frequent diarrhea, a common symptom of celiac disease, can cause severe dehydration, electrolyte imbalance, and nutrition loss, as well.

Finally, because patients with celiac disease are preoccupied with avoiding trigger foods and flareups, they are prone to disordered eating habits such as food rationing, restriction, and avoidance.

These behaviors, in turn, can lead to social isolation, triggering a vicious cycle.

What You Can Do If You Suffer Celiac Disease Symptoms

Untreated, celiac disease can develop into critical complications, including injury to the nervous system, small bowel cancer, and seizures. If you experience persistent symptoms, we recommend you consult a specialist for a proper diagnosis.

This is what you can expect during that visit:

You will likely undergo a blood test and possible genetic sampling (such as a cheek swab). Prepare to eat gluten before testing; it needs to be in your system for reliable results.

Depending on test readings, your doctor might further order an internal review of your intestinal tract using a slim scope equipped with a lighted camera (a procedure called an endoscopy).

Treatment for celiac disease primarily involves adopting a gluten-free diet, as no medications have yet been approved. However, the Food and Drug Administration in 2025 gave fast-track designation to investigate an antibody drug designed to treat celiac disease. Stay tuned!

Until then, be easy on yourself. Stress-reducing activities such as calm breathing exercises, support groups, and light exercise can pull your mind out of the vicious food cycle and toward more positive opportunities.
