Small Bowel Obstruction
- Adhesions—scar tissue left behind, in most cases by previous abdominal surgery
- Intussusception—telescoping of the intestinal wall
- Volvulus—the intestine twists on itself
- Impacted foreign bodies—items that were swallowed and got stuck

- Crohn’s disease—an inflammatory bowel condition

- Decreased blood supply to the small bowel
- Abnormal growth of tissue in or next to the small intestine
- Tumors in the small intestine
- Infection in the lining of the small intestine
- Kidney disease
- Long-standing diabetes
- Rarely, gallstones
- Abdominal fullness and/or excessive gas
- Distension—abdomen feels stretched out more than normal
- Pain and cramps in stomach area
- Bad breath
- Monitoring and IV fluids—At the hospital, doctors will watch closely to see if the blockage will get better on its own, which is often the case in the event of a paralytic ileus. No food will be allowed and fluids will be given through an IV.
- Nasogastric tube—A tube is inserted through the nose and into the stomach to remove fluids and gas, which can promptly relieve pain and pressure. It will be left in place until the intestines are working well.
- Catheterization—A tube is placed in the bladder to drain and test urine.
- Pain relievers
- Oral triple therapy—to reduce gas, bloating, and improve symptoms
- Muscle stimulants—to promote muscle contraction in the intestine
- Antibiotics—to treat bacterial infections
- Intestinal strangulation, which may be caused by volvulus or intussusception
- Abdominal adhesions
