<<Disclaimer: Verify this information before applying it to your situation.>> There is a definite incidence of celiac disease in type one diabetes in causcasians at least. Anywhere from of 3.3% to 10 % of people with type one diabetes willl have or develope celic disease. Any form of diabetes can lead to gastroparesis, usually after many years of diabetes. The symptoms can be similar in many ways, bloating after meals, abdominal pain. Diarrhea is not usually caused by the gastroparesis itself. ( diabetic diarrhea may occur as part of the the nerve damage caused by the lonGstanding diabetes). I have several patients who have diabetes, gastroparesis and celiac disease. Certainly identifying the celiac disease oftenn makes a big difference to the symptoms. Joe Murray Univ of Iowa Not medical advice
