Reading your post struck a chord with me...your experiences with frequent childhood illnesses (pnemonia and strep throat for me, as well as the usual colds), late onset of menstruation, dizziness, fatigue, etc, this all sounds like me, in addition to chronic constipation that occasionally alternates with diarrhea, bloating, gas, pain...I thought celiac disease manifested itself as intense bouts of diarrhea after consuming gluten. Is it possible that it can show up with all these symptoms? How long would you need to go gluten free to feel a difference? My doctor never proposed this as a possibility to explain my symptoms. I am having an endoscopy and colonoscopy done in October. Should I bring this up to my doctor so she can test me for CD?
