Gas pains and bloating experienced following a colonoscopy may be eased by walking and moving around, according to Eugene Gastroenterology Consultants. Both are normal occurrences following a colonoscopy procedure. Flatulence, or passing of gas, is also normal.
The introduction of air into the colon during a colonoscopy sometimes causes lingering abdominal bloating and gas, notes Eugene Gastroenterology Consultants. This air is introduced to enhance visualization during the procedure and to allow the colonoscope to move through the large intestine more efficiently. In addition, the air smoothes out the wrinkled wall of the bowel so the physician can get a better look.
Gas usually subsides within 24 hours, advised Eugene Gastroenterology Consultants. Patients are instructed to avoid eating large amounts of food following the procedure until a normal state of comfort is achieved. Patients may experience a loose stool or may not have a bowel movement for up to three days after the colonoscopy; milk of magnesia or a fiber supplement may be used to encourage movement of the bowels.
Although not common, abdominal gas and the medications that are used during the colonoscopy procedure may cause nausea, warns Eugene Gastroenterology Consultants. When this occurs, a clear liquid diet is recommended. Any resultant vomiting that lasts for longer than six hours should be evaluated by a physician.
