Sorbitol may be used as a laxative. Because it is slowly digested by the intestine, it tends to linger and draw water into the interior of the gut. This increased liquidity can facilitate the passage of stools. Sorbitol is also in many medicines for children, where it helps to make them more palatable for consumption.
