Abdominal Wall Hernia
An abdominal wall hernia is a protrusion of the intestine through an opening or area of weakness in the abdominal wall.
- There are various types of hernia, including inguinal hernia, umbilical hernia, femoral hernia, incisional hernia, incarcerated hernia, strangulated hernia, and sports hernia.
- An abdominal wall hernia causes a noticeable bulging but little discomfort.
- The diagnosis is made by physical examination and sometimes ultrasonography or a computed tomography scan.
- Treatment involves surgery to repair the hernia.
Abdominal hernias are very common, particularly among men. There are about 700,000 hernia operations each year in the United States. Hernia can also occur in children. Hernias are usually named for the area in which they occur.
The abdominal wall is thick and tough in most places, so hernias usually occur in an area of weakness where a previous opening has closed. Heavy lifting or straining may make a hernia more obvious but does not cause a hernia to form.
