What is Celiac Disease?

Celiac disease is a lifelong autoimmune condition where eating gluten - a protein in wheat, barley and rye - makes the immune system attack the small intestine. The attack flattens the tiny finger-like villi that absorb food, so nutrients pass through unused. It is not a food allergy and not a lifestyle choice; it is a defined medical condition with a defined treatment.

What actually happens inside

In a susceptible person, gluten fragments trigger an immune response that damages the intestinal lining. Villi that should look like a dense carpet become a flat floor. Iron, calcium, vitamins, protein and calories stop absorbing properly - which is why celiac disease can show up as anemia, weak bones or stunted growth long before anyone connects it to food.

How common, and how missed

About 1 in 100 people worldwide have celiac disease, and India is no exception - especially the wheat-eating north. Most remain undiagnosed for years because the symptoms disguise themselves as "weakness", IBS, anemia or stress. A simple blood test finds most cases.

The treatment in one line

There is no medicine for celiac disease - and it needs none. A strict, lifelong gluten-free diet is the complete treatment: remove the trigger, the immune attack stops, the villi regrow, and life returns to normal. The rest of this series explains the diet, the tests, and how classical Ayurvedic wisdom can support (never replace) that core discipline.

Who should suspect it

Chronic loose motions or bloating, unexplained iron-deficiency anemia, fatigue, mouth ulcers, poor growth in a child, infertility or repeated miscarriages, an itchy blistering rash on elbows or knees - any of these, especially with a family history, deserves the celiac blood test before anything else.

One-line summary

Celiac disease is gluten-triggered immune damage to the small intestine that blocks nutrient absorption - fully controlled, though never cured, by a strict lifelong gluten-free diet.
