Celiac disease is an autoimmune disorder that affects the small intestine. It is triggered by consuming gluten, a protein found in wheat, barley, and rye.

In individuals with celiac disease, the immune system reacts to gluten as if it were a foreign invader, causing damage to the small intestine's lining and reducing its ability to absorb nutrients from food. This can lead to a range of symptoms, including bloating, diarrhea, constipation, abdominal pain, ... See more

Celiac disease is an autoimmune disorder that disrupts the body's ability to digest gluten. Gluten is a dietary protein in wheat products; the disease also affects some related proteins found in barley and rye. Celiac causes the small intestine to become inflamed when exposed to gluten; the inflammation can damage or destroy the intestine's lining.

The intestinal wall is studded with villi, projecting folds of tissue that increase the surface area available to absorb nutrients (including vitamins, fluids, minerals, and electrolytes) from food. When a person with celiac disease eats gluten, it triggers the body's immune system. Immune cells will attack the intestinal villi. This immune response usually, but not always, involves the production of auto-antibody proteins by the immune system.

The harmful immune response and autoantibody production will continue if the individual is exposed to gluten and the other relevant proteins. Over time, the immune ... See more
