Celiac disease is an autoimmune disorder. People with one autoimmune disorder are prone to getting other autoimmune disorders – though this is not guaranteed. For people with celiac disease, the later the age of diagnosis, the greater the chance of developing another autoimmune disorder. Other conditions and some cancers are also associated with celiac disease.
The estimated prevalence of celiac disease in patients with type 1 diabetes is approximately 6%. Most patients with both conditions have asymptomatic celiac disease, or symptoms that may be confused for symptoms of their diabetes. For this reason, screening for celiac disease is recommended after a diagnosis of type 1 diabetes.
Studies debate the extent of the connection between Crohn’s disease and celiac disease, but all conclude that Crohn’s disease is more common in those with celiac disease than in the general population. Overlapping symptoms include abdominal pain, diarrhea, anemia, and short stature.
