<<Disclaimer: Verify this information before applying it to your situation.>> Hello Cathy, My daughter Sara, is both IDDM and Celiac. She was diagnosed at 16 months with Celiac, and at 8 years old as a diabetic. Speaking for myself(her father) I would say that the diabetes is the toughest one to control. With Celiac you need to read the labels and you know what you can and can't eat. But with diabetes you can do everything to make sure your bg's are in a good range and they may be high or low. There are so many influencing factors with diabetes; a cold, exercise, lack of exercise, amount of carbs., etc. It should be interesting to see what other people have to say. Thank You.
