Constipation: Your experience of a change in bowel habits following a colonoscopy regimen isn't rare. Drinking adequate amounts of fluids, eating enough fiber and/or taking a fiber supplement daily, exercising all are helpful in returning regular bowel function. If you have no urges for BM's, I recommend taking a bowel stimulant like SenokotS regularly according to instructions. Avoid harsh laxatives.
