Abdominal Pain, Adhesions from Surgery

Surgery on the abdomen can cause bands of fibrous scar tissue (also known as adhesions) to form. This is the most common side effect of any abdominal surgery. Adhesions can form bands around the intestine and cause a partial or complete blockage of the intestinal tract (intestinal obstruction).  A blocked intestine requires surgery.


Abdominal adhesions can cause these symptoms:

  • Severe abdominal pain, acute or chronic

  • Nausea and vomiting

  • Bloating

  • Inability to pass gas or stool

Adhesions are more common in people who have had one or more abdominal surgeries. Diagnosis is made using blood tests, X-ray, CT scan, rectal exam, and (in women) pelvic exam. Abdominal adhesions are permanent. They can be treated by surgery to remove the scar tissue. However, this treatment may create more scar tissue, and the problem may reoccur.

Pelvic adhesions can cause female infertility.

Home care

  • Rest as needed, until feeling better.

  • Eat a diet low in fiber (called a low-residue diet). Foods allowed include refined breads, white rice, fruit and vegetable juices without pulp, tender meats. These foods will pass more easily through the intestine.

  • Don't eat whole-grain foods, whole fruits and vegetables, tough meats, seeds or nuts until your symptoms go away.

Follow-up care

Follow up with your healthcare provider, or as advised. 

If X-rays were done, they will be read by a radiologist and you will be notified if there are any changes.

Call 911
