What is Celiac Disease ?

Celiac disease is an autoimmune disorder in which the immune system responds negatively to the gluten protein found in wheat and other grains.

When someone has celiac disease, their immune system incorrectly reads gluten proteins as invaders. In gluten intolerance, there is no cell damage or inflammation. It's more of a sensitivity:

This miscue triggers T-cells, which function as the body’s disease fighting soldiers, to release cytokines and attack. This attack causes inflammation and -tissue destruction in the small intestine. In celiacs, the smallest amount of a gluten protein can lead to a major episode.

People with celiac disease have a serious allergy, whereas people with gluten sensitives have some issue with gluten without any evidence of coeliac disease.
