Intestinal obstruction is a blockage that keeps food or liquid from passing through your small intestine or large intestine (colon). Causes of intestinal obstruction may include fibrous bands of tissue (adhesions) in the abdomen that form after surgery; hernias; colon cancer; certain medications; or strictures from an inflamed intestine caused by certain conditions, such as Crohn’s disease or diverticulitis.

Without treatment, the blocked parts of the intestine can die, leading to serious problems. However, with prompt medical care, intestinal obstruction often can be successfully treated.

Symptoms

Signs and symptoms of intestinal obstruction include:

• Crampy abdominal pain that comes and goes
• Loss of appetite
• Constipation
• Vomiting
• Inability to have a bowel movement or pass gas
• Swelling of the abdomen

Causes

The most common causes of intestinal obstruction in adults are:

• Intestinal adhesions — bands of fibrous tissue in the abdominal cavity that can form after abdominal or pelvic surgery
• Hernias — portions of intestine that protrude into another part of your body
• Colon cancer

In children, the most common cause of intestinal obstruction is telescoping of the intestine (intussusception).

Other possible causes of intestinal obstruction include:

• Inflammatory bowel diseases, such as Crohn’s disease
• Diverticulitis — a condition in which small, bulging pouches (diverticula) in the digestive tract become inflamed or infected
• Twisting of the colon (volvulus)
• Impacted feces
