Short Bowel Syndrome

Short bowel syndrome is a problem that occurs when part of the small intestine is missing or has been removed during surgery. Nutrients are not properly absorbed into the body as a result.

Causes:
The small intestine absorbs much of the nutrients found in foods we eat. When two-thirds or more of the small intestine is missing, the body may not absorb enough food to stay healthy and maintain your weight.

Some infants are born missing part or much of their small intestine.

More often, short bowel syndrome occurs because much of the small intestine is removed during surgery. This type of surgery may be needed:

After gunshots or other trauma damaged the intestines
For someone with severe Crohn disease
For infants, often born too early, when part of their intestines dies
When blood flow to the small intestine is reduced due to blood clots or narrowed arteries
