Glycerin suppositories used as laxatives.
A laxative is a food or drug taken to make bowel movements easier, or to treat constipation. Sometimes taking powerful or lots of laxatives can cause diarrhea or a flatulence.
Laxatives work by helping your intestines digest undigested food, and do not make you lose weight. Despite this, some people with eating disorders take laxatives in an attempt to lose weight.
