aperient

adj. purgative, laxative (Medicine)

Laxatives are foods, compounds, or drugs taken to induce bowel movements, most often taken to treat constipation. Certain stimulant, lubricant, and saline laxatives are used to evacuate the colon for rectal and bowel examinations. They are sometimes supplemented by enemas. Often, taking powerful laxatives can cause diarrhea, accompanied by massive flatulence attacks, due to the overworking of the bowels. Some people who experienced these side effects produced more than three times the average daily amount of flatulence in just one bowel release. Laxatives are often abused by people with eating disorders. Laxative abuse is potentially serious since it can lead to intestinal paralysis, Irritable Bowel Syndrome (IBS), pancreatitis, renal failure, and other problems.
