My son gets bouts of intestinal cramping, no diarrhea or constipation ever, almost monthly to the date. We have almost completely eliminated gluten, but it is difficult to cook for the entire family at times. The bouts of diagnosed IBS/GERD leave him feeling just awful and tired and sick and not wanting to do anything or go anywhere - not your usual teenage behavior. He has missed 28 days of school already this year. The pediatric gastroenterologist will be doing a colonoscopy and endoscopy at the end of March.
