Diverticulitis

Complications

About 25% of people with acute diverticulitis develop complications, which may include:

  • An abscess, which occurs when pus collects in the pouch.
  • A blockage in your bowel caused by scarring.
  • An abnormal passageway (fistula) between sections of bowel or the bowel and other organs.
  • Peritonitis, which can occur if the infected or inflamed pouch ruptures, spilling intestinal contents into your abdominal cavity. Peritonitis is a medical emergency and requires immediate care.
