    What causes Short Bowel Syndrome ?
    ### Response:
    The main cause of short bowel syndrome is surgery to remove a portion of the small intestine. This surgery can treat intestinal diseases, injuries, or birth defects.
                
Some children are born with an abnormally short small intestine or with part of their bowel missing, which can cause short bowel syndrome.
