Hi Don and Patty, >How could celiac disease be the cause? According to Joseph Murray, MD, one >of the leading celiac researchers in the US, "For young untreated celiac >girls, the onset of menarche can be delayed. Like so many other symptoms, >these problems are caused by malabsorption. " Just because early menarche has not been listed as a symptom of CD, doesn't mean that it isn't a symptom, don't you think? Being overweight didn't used to be a symptom either until recently. I stopped my period completely from the age of 16-22, another symptom of celiac disease. All the best, Susan
