Short Bowel Syndrome (SBS) is a condition that occurs when a person has a shortened length of the small intestine, which is the part of the digestive system responsible for absorbing nutrients from food. This can be caused by a variety of factors, including surgery, Crohn's disease, or other medical conditions. Symptoms of SBS include diarrhea, dehydration, malnutrition, and weight loss. Treatment typically involves dietary changes, medications, and sometimes surgery.
