Internal Storm? Why Your Body Attacks Every Bite: Celiac Disease Next Steps

If you've been told you may have celiac disease, or you suspect it, you might feel confused. How can food — something meant to nourish you — trigger your body to attack itself?

Celiac disease is not a food intolerance or a simple digestive issue. It is an autoimmune disease. That means your immune system, which normally protects you from infections, mistakenly attacks your own body when you eat gluten.

Understanding what's happening inside you is the first step toward taking control.

What Is Celiac Disease?

Celiac disease is a chronic autoimmune disorder triggered by gluten. Gluten is a protein found in:

• Wheat
• Barley
• Rye
• Foods made from these grains (bread, pasta, cereal, baked goods)

When someone with celiac disease eats gluten, their immune system reacts by damaging the lining of the small intestine.

Inside your small intestine are tiny finger-like structures called villi. These villi absorb nutrients from food. In untreated celiac disease, the immune attack flattens and damages these villi.

The result? Your body cannot properly absorb nutrients — even if you're eating well.

Why Does the Body Attack Gluten?

In people with celiac disease, gluten is misidentified as a threat. The immune system launches an inflammatory response that harms the intestinal lining.

This reaction is not mild. It is ongoing and progressive as long as gluten is consumed.

Over time, untreated celiac disease can lead to:

• Nutrient deficiencies (iron, calcium, vitamin D, B12)
• Anemia
• Bone loss (osteoporosis)
• Fertility issues
• Growth problems in children
• Nerve damage
• Increased risk of certain intestinal cancers (rare, but possible)

This is why celiac disease must be taken seriously — but also why early diagnosis and treatment make a powerful difference.

Symptoms of Celiac Disease

Celiac disease looks different in different people. Some have classic digestive symptoms. Others do not.

Common Digestive Symptoms

• Chronic diarrhea or constipation
• Bloating
• Gas
• Abdominal pain
• Nausea
• Fatty or foul-smelling stools
• Unexplained weight loss

Non-Digestive Symptoms

• Chronic fatigue
• Iron-deficiency anemia
• Joint pain
• Skin rash (dermatitis herpetiformis)
• Brain fog
• Depression or anxiety
• Tingling in hands or feet
• Delayed growth in children

Some people with celiac disease have no obvious symptoms at all — but intestinal damage is still occurring.

If you're experiencing persistent digestive problems or unexplained nutrient deficiencies, it may be worth exploring whether celiac disease is involved.

Because celiac disease disrupts your body's ability to absorb nutrients properly, you might also want to check if you're showing signs of Malabsorption Syndrome / Protein Losing Gastroenteropathy using a free online symptom checker to help identify patterns that warrant discussion with your doctor.

How Is Celiac Disease Diagnosed?

Diagnosis should always be done while you are still eating gluten. Removing gluten before testing can interfere with results.

Step 1: Blood Tests

Doctors typically start with blood tests that check for specific antibodies linked to celiac disease, such as:

• Tissue transglutaminase (tTG-IgA)
• Endomysial antibodies (EMA)

These tests are highly reliable when gluten is still in the diet.

Step 2: Small Intestine Biopsy

If blood tests are positive, a gastroenterologist may recommend an upper endoscopy to take small samples from your small intestine. This confirms villi damage.

In children, sometimes diagnosis can be made without biopsy if antibody levels are very high and other criteria are met.

Never self-diagnose celiac disease. Proper testing is essential.

The Only Treatment for Celiac Disease

Currently, the only proven treatment for celiac disease is a strict, lifelong gluten-free diet.

There is no medication that replaces this.

A gluten-free diet means eliminating:

• All wheat
• All barley
• All rye
• Foods contaminated by these grains

Even small amounts of gluten — crumbs or cross-contamination — can trigger immune damage.

This may sound overwhelming at first. But most people improve dramatically once gluten is removed.

---

What Happens After You Go Gluten-Free?

When someone with celiac disease follows a strict gluten-free diet:

• Intestinal inflammation decreases
• Villi begin to heal
• Nutrient absorption improves
• Symptoms often resolve within weeks to months
• Energy levels increase
• Blood tests normalize

Healing takes time. In adults, full intestinal recovery can take months to years. Children often heal faster.

Consistency is key. "Mostly gluten-free" is not enough for celiac disease.

Hidden Sources of Gluten

Managing celiac disease requires attention to detail.

Gluten can hide in:

• Soy sauce
• Salad dressings
• Processed meats
• Sauces and gravies
• Certain medications and supplements
• Oats that are not certified gluten-free
• Shared toasters or cooking surfaces

Working with a registered dietitian who understands celiac disease can make this transition smoother and safer.

---

Long-Term Outlook

The good news: When treated properly, people with celiac disease can live long, healthy lives.

However, untreated celiac disease can lead to serious complications, including:

• Severe malnutrition
• Fractures due to bone loss
• Infertility or pregnancy complications
• Neurological issues
• Rare but serious intestinal cancers

This is not meant to alarm you — but to emphasize why early diagnosis and consistent treatment matter.

The earlier celiac disease is identified, the better the outcome.

When to Speak to a Doctor

You should speak to a doctor promptly if you experience:

• Persistent diarrhea lasting more than two weeks
• Unexplained weight loss
• Severe abdominal pain
• Vomiting that doesn't stop
• Signs of severe anemia (shortness of breath, dizziness, chest pain)
• Blood in stool

These symptoms may signal something serious or even life-threatening. Do not delay medical evaluation.

Even milder symptoms deserve attention. Chronic fatigue, anemia, or digestive discomfort are not things you have to "just live with."

Emotional Impact of Celiac Disease

Living with celiac disease can affect more than just your body.

It can impact:

• Social events
• Travel
• Family meals
• Emotional well-being

It's normal to feel frustrated or overwhelmed at first. But many people report that once they adjust to a gluten-free lifestyle and begin to feel better physically, their confidence and quality of life improve significantly.

Support groups, online communities, and dietitian guidance can make a meaningful difference.

Key Takeaways About Celiac Disease

• Celiac disease is an autoimmune condition triggered by gluten.
• It damages the small intestine and prevents proper nutrient absorption.
• Symptoms vary widely and may be digestive or non-digestive.
• Diagnosis requires blood testing and sometimes biopsy while eating gluten.
• The only treatment is a strict, lifelong gluten-free diet.
• Untreated celiac disease can lead to serious complications.
• With proper management, most people recover and thrive.

Final Thoughts

If it feels like your body is reacting to every bite, you are not imagining it. Celiac disease is real, measurable, and medically recognized.

The most important next step is this: Do not guess. Get tested.

If you suspect celiac disease or have persistent digestive issues, speak to a qualified healthcare provider. Proper testing, medical supervision, and professional dietary guidance are essential — especially because untreated celiac disease can become serious.

Your body is not "overreacting." It is responding to something it believes is harmful. With the right diagnosis and a clear plan, you can calm the internal storm and restore your health.

If you are experiencing severe symptoms or anything that could be life-threatening, seek immediate medical care.
