Celiac disease occurs from an interaction between genes, eating foods with gluten and other environmental factors, but the precise cause isn't known. Infant feeding practices, gastrointestinal infections and gut bacteria might contribute to developing celiac disease.
Sometimes celiac disease is triggered — or becomes active for the first time — after surgery, pregnancy, childbirth, viral infection or severe emotional stress.
Some gene variations appear to increase the risk of developing the disease. But having those gene variants doesn't mean you'll get celiac disease, which suggests that additional factors must be involved.
The rate of celiac disease in Western countries is estimated at about 1 percent of the population. Celiac disease is most common in Caucasians; however, it is now being diagnosed among many ethnic groups and is being found globally.
Key words: causes celiac disease; causes celiac disease develop; celiac disease causes.
