Short bowel syndrome is a group of problems related to poor absorption of nutrients that typically occurs in people who have had half or more of their small intestine removed.
The small intestine and the large intestine, also called the colon, make up the bowel. The small intestine is where most digestion of food and absorption of nutrients occur. People with short bowel syndrome cannot absorb enough water, vitamins, and other nutrients from food to sustain life.
The bowel is made up of the small and large intestines. The small intestine includes three sections—the duodenum, jejunum, and ileum.
