Known Complications of Celiac Disease
Infertility and Pregnancy Issues
Suspected Complications of CD
Apthous ulcers(sores in soft mucous membranes of the mouth and tongue)
Dysrhythmia(abnormal heart rate)
Insulin Dependent Diabetes
Autoimmune Thyroid Disease
I believe that all the suspected complications are true too, I think in Dr. Peter Green's book he says some of Sylvia's suspected complications have been proven! I really can't say enough that.... if you have a autoimmune problem or just feel off...EVERYONE should be tested for Celiac Disease. It is THE MOST UNDER DIAGNOSED disease in America! You can do Gene Testing(tells whether you have the Celiac gene), Blood testing(if positive you go on to test by endoscopy) and then the endoscopy.
