What is the difference between celiac disease and gluten sensitivity?

Celiac disease is an autoimmune disorder where gluten consumption triggers an immune attack on the small intestine, causing villi destruction and malabsorption. Non-celiac gluten sensitivity (NCGS) causes similar symptoms but WITHOUT intestinal damage or autoimmune markers. Both require gluten avoidance, but celiac requires stricter elimination (even trace amounts).

How do I get properly tested for celiac disease?

Critical: You MUST continue eating gluten before testing — going gluten-free before tests gives false negatives. Testing: (1) Blood test: tTG-IgA antibody, EMA-IgA (most sensitive), total serum IgA, (2) If positive: endoscopy with small intestinal biopsy for confirmation, (3) Genetic testing: HLA-DQ2/DQ8 (rules out celiac if negative).

Can you develop gluten intolerance as an adult?

Yes — celiac disease can develop at any age, even in people who previously tolerated gluten. Onset is often triggered by: pregnancy, surgery, severe infection, significant emotional stress, or gut microbiome disruption. Late-onset celiac (diagnosed after 60) is increasingly common.

What are the 'silent' celiac symptoms people miss?

Many celiac sufferers have no classic digestive symptoms but instead experience: iron deficiency anemia, osteoporosis, infertility, recurrent miscarriages, liver enzyme elevation, peripheral neuropathy (numbness/tingling), dental enamel defects, dermatitis herpetiformis (itchy blistering rash), and chronic fatigue.

Does a gluten-free diet help if I don't have celiac disease?

For non-celiac gluten sensitivity (NCGS), yes — a gluten-free diet resolves symptoms in 4–6 weeks. However, many people who 'feel better' gluten-free have actually reduced FODMAPs (fructans in wheat) rather than gluten itself. If you suspect gluten is an issue, proper testing is important before eliminating it permanently.

What hidden sources of gluten should I know about?

Hidden gluten sources: soy sauce, most salad dressings, malt vinegar, beer, communion wafers, some medications, imitation crab meat, couscous (often mistaken for grain-free), licorice, some oats (contamination), sauces/gravies, modified food starch, some cosmetics (lip products can be ingested).
