Celiac Disease
Celiac disease is an autoimmune disorder where eating gluten damages the small intestine. The only treatment is a strict, lifelong gluten-free diet.
Overview#
Celiac disease is a serious autoimmune disorder that occurs in genetically predisposed people where the ingestion of gluten leads to damage in the small intestine. Gluten is a protein found in wheat, barley, and rye. When people with celiac disease eat gluten, their immune system responds by damaging the villi, small finger-like projections in the small intestine that absorb nutrients.
Celiac disease affects about 1% of the population, though many cases go undiagnosed. The only treatment is a strict, lifelong gluten-free diet. When gluten is removed from the diet, the small intestine heals, and symptoms improve. However, even small amounts of gluten can cause damage.
Symptoms#
Celiac disease symptoms vary widely and may include:
Digestive Symptoms:
- Diarrhea
- Abdominal pain and bloating
- Constipation
- Nausea and vomiting
- Gas
- Fatty, foul-smelling stools
- Weight loss
Non-Digestive Symptoms:
- Fatigue
- Anemia (iron deficiency)
- Bone or joint pain
- Depression or anxiety
- Headaches
- Mouth ulcers
- Skin rash (dermatitis herpetiformis)
- Infertility or miscarriage
- Osteoporosis
- Neurological symptoms
Children May Have:
- Failure to thrive
- Delayed growth
- Delayed puberty
- Dental enamel defects
- Irritability
- Short stature
Some people have no symptoms (silent celiac disease) but still have intestinal damage.
When to Seek Immediate Care#
Seek emergency care if:
- Severe abdominal pain
- Severe dehydration
- Signs of severe malnutrition
- Severe symptoms
Self-care & Home Management#
Managing celiac disease requires strict adherence to a gluten-free diet:
-
Strict Gluten-Free Diet (only treatment):
- Avoid: Wheat, barley, rye, and products containing them
- Read labels carefully: Gluten can be in many foods
- Be aware of cross-contamination: Separate utensils, cutting boards
- Lifelong commitment: No exceptions
- Even small amounts cause damage
-
Foods to Avoid:
- Bread, pasta, cereals (unless gluten-free)
- Baked goods
- Beer
- Many processed foods
- Some medications (check with pharmacist)
- Some cosmetics (if ingested)
-
Safe Foods:
- Fruits and vegetables
- Meat, poultry, fish (unprocessed)
- Dairy products
- Rice, corn, quinoa
- Gluten-free grains
- Legumes, nuts, seeds
-
Learn to Read Labels:
- Look for "gluten-free" label
- Check ingredient lists
- Be aware of hidden sources
- When in doubt, don't eat it
-
Prevent Cross-Contamination:
- Separate toaster for gluten-free bread
- Clean surfaces thoroughly
- Separate cutting boards and utensils
- Be careful when eating out
-
Nutritional Support:
- May need supplements (iron, calcium, vitamins)
- Work with dietitian
- Ensure adequate nutrition
- Monitor nutrient levels
-
Support:
- Join celiac support groups
- Educate family and friends
- Work with dietitian
- Don't isolate
When to Seek Care#
Contact Healthcare Provider#
- Suspected celiac disease
- Symptoms not improving on gluten-free diet
- Need for diagnosis
- Questions about diet
- Nutritional concerns
- Need for follow-up testing
Self-care is Appropriate#
- Following strict gluten-free diet
- Symptoms well-controlled
- Regular follow-up scheduled
- No new concerns
Tests & Diagnostics#
Diagnosing celiac disease involves:
-
Blood Tests (first step):
- tTG-IgA test: Most common screening test
- EMA test: More specific
- Total IgA: To check for IgA deficiency
- Other antibody tests: As needed
- Important: Must be eating gluten for accurate results
-
Endoscopy with Biopsy (to confirm):
- Scope into small intestine
- Take tissue samples
- Look for damage to villi
- Gold standard for diagnosis
- Must be eating gluten before test
-
Genetic Testing (sometimes):
- HLA-DQ2 and HLA-DQ8 genes
- If negative, celiac disease unlikely
- If positive, doesn't mean you have it
- Used in some cases
Important: Don't start gluten-free diet before testing, as it can affect test results.
Treatment#
Only Treatment: Strict Gluten-Free Diet:
-
Complete Elimination:
- No wheat, barley, rye
- No exceptions
- Lifelong commitment
- Even small amounts cause damage
-
Healing Process:
- Intestine begins healing within days
- Most people feel better within weeks
- Complete healing may take months to years
- Villi can regenerate
-
Symptom Improvement:
- Digestive symptoms improve first
- Other symptoms may take longer
- Some damage may be permanent
- Early treatment is best
-
Nutritional Support:
- Supplements if needed
- Ensure adequate nutrition
- Work with dietitian
- Monitor nutrient levels
-
Follow-up Care:
- Regular check-ups
- Monitor antibody levels
- Assess healing
- Adjust as needed
Prevention#
Celiac disease cannot be prevented, but:
- Early Diagnosis: Prevents complications
- Strict Diet: Prevents damage
- Regular Monitoring: Detects problems early
- Education: Helps with compliance
What Happens in the Body#
In celiac disease:
- Gluten Ingestion: Person with celiac eats gluten
- Immune Response: Immune system attacks gluten
- Intestinal Damage: Villi become damaged and flattened
- Malabsorption: Can't absorb nutrients properly
- Symptoms Develop: Various symptoms appear
- Healing: When gluten removed, intestine heals
Causes:
- Genetics: Runs in families
- Immune system: Autoimmune response
- Gluten: Triggers the response
- Environmental factors: May play a role
Life-stage Considerations#
Children#
- Can develop at any age
- May have growth problems
- Early diagnosis important
- Family education crucial
- School accommodations needed
Adults#
- Can develop at any age
- May have been undiagnosed for years
- May have complications
- Lifestyle adjustments needed
Older Adults#
- May be newly diagnosed
- May have complications
- May need more support
- Regular monitoring important
Complications#
If Untreated, Can Lead To:
- Malnutrition
- Osteoporosis
- Infertility
- Neurological problems
- Some cancers (rare, but increased risk)
- Other autoimmune diseases
FAQ#
Can celiac disease be cured?#
There's no cure, but a strict gluten-free diet effectively treats it. The intestine heals, and symptoms resolve. However, you must maintain the diet for life.
What happens if I accidentally eat gluten?#
You may experience symptoms, and intestinal damage can occur. The severity depends on the amount and your sensitivity. Most people recover, but it's important to be strict.
Can I ever eat gluten again?#
No. Even after healing, eating gluten will cause damage again. The diet must be lifelong, with no exceptions.
Is celiac disease the same as gluten sensitivity?#
No. Celiac disease is an autoimmune disorder with intestinal damage. Non-celiac gluten sensitivity causes symptoms but no intestinal damage.
Will my children have celiac disease?#
There's a genetic component, so children of people with celiac disease are at higher risk. However, not all will develop it. Screening may be recommended.
