How serious is celiac disease?
Celiac disease is a serious autoimmune disease. It can cause damage to the small intestine and if left undiagnosed or untreated, it can result in long-term health complications, such as anemia, infertility, and heart disease, among other conditions. Those with celiac disease have twice the risk of developing coronary artery disease and four times the risk of developing small bowel cancers as the general population.
