Gluten causes inflammation of the small intestine in people with celiac disease, which is an autoimmune disease diagnosed with a blood test or biopsy; other symptoms include digestive problems, anemia, fatigue, headaches and joint pain. Avoiding gluten is the treatment, though there is no cure. Left untreated, celiac disease can lead to severe intestinal damage and osteoporosis, among other conditions.
Other people have a less severe sensitivity that may be an allergy to wheat, or what's called non-celiac gluten sensitivity that causes such symptoms as digestive discomfort.
