Cause
Although the exact cause of
celiac disease is not known, having certain
genes increases your risk. You are more likely to have
these genes and may get celiac disease if you have a first-degree relative
(mother, father, brother, sister, son, or daughter) with the condition.
Environmental factors, such as viral or bacterial infections, may trigger
changes in the small intestine of a person with these genes. Then, eating foods
that contain gluten can trigger an abnormal
immune system response. Eventually, digestion and
absorption problems may result.
Research continues on how
genetic, environmental, and immune factors interact and affect a person's
symptoms, at what age they begin, and whether long-term health problems
develop.
