Short bowel syndrome
Short bowel syndrome is a condition in which nutrients are not properly absorbed (malabsorption) because a large part of the small intestine is missing or has been surgically removed.
Small intestine insufficiency
When areas of the small intestine are removed by surgery, or they are missing due to a birth defect (congenital defect), there may not be enough surface area left in the remaining bowel to absorb enough nutrients from food.
This condition is likely to develop when one-half or more of the bowel is removed during surgery. Risk factors include diseases of the small intestine that may require surgery, such as Crohn's disease. Necrotizing enterocolitis is a common cause of short bowel syndrome in infants.
Exams and Tests
Treatment is aimed at relieving symptoms, and may include:
- A high-calorie diet that supplies essential vitamins and minerals, as well as certain types of carbohydrates, proteins, and fats
- Some vitamins and minerals may need to be given by injection
- Treatment for anemia with vitamin B-12, folic acid, and increased dietary iron
- Medications to slow down the normal movement of the intestine (lengthens the time nutrients spend in the small intestine)
- Tube feeding through a vein (parenteral nutrition), if normal feeding is not delivering enough nutrients (patients can sometimes return to normal eating once they have stabilized)
The condition may improve over time if it occurs as a result of surgery. There may be a gradual improvement in nutrient absorption.
When to Contact a Medical Professional
Call for an appointment with your health care provider if you develop symptoms of short bowel syndrome, especially if you recently had bowel surgery.
