IMODIUM® is an oral anti-diarrheal agent which slows down the motility of the intestinal wall, allowing the body to reabsorb any excess liquid.
What happens in your body to cause the uncomfortable phenomenon of diarrhea is really quite simple. Normally, food and liquids follow a path from the stomach into the small intestine where nutrients and water are absorbed, and then into the colon where undigested waste can be stored and later expelled.
Sometimes, infection, poison, inflammation or a variety of other events can hamper the normal operation of the small intestine or colon and the rate at which nutrients and water are absorbed. The normally slow, wavelike movement of the intestinal tract can become hyperactive, moving food and fluids through the colon too quickly. This results in watery stools - better known as diarrhea.
