My 7 year old daughter has HEDS. Her twin brother just had a colonoscopy/endoscopy bc of stomach pain/constipation which seemed to be potentially related to eating gluten. When they did the tests they found he had an extremely floppy colon going every which way, and also inflammation in the duodenum. I brought up the HEDS (again) and the doctor said that that can cause the floppy colon. Has anyone heard of inflammation caused by EDS? What are the typical GI symptoms for HEDS?
