Treatment includes colonic evacuation, establishing regular bowel habits, eating a balanced diet with dietary fiber and laxatives to keep the stool soft and help promote the normal motility patterns.

The dose when used as a maintenance medication is 0.5 -1 gram/kg/day divided BID. The dose can be titrated to have one soft stool per day. The differential diagnosis of constipation can be reviewed here.

This leads to failure of the intestinal contents to pass through the intestinal tract. Proximal to the obstruction is swallowed air and abdominal contents and secretions. The abdominal contents cannot move distal to the obstruction causing no flatus and bowel movements. If the obstruction is high in t...
