ComplicationsBy Mayo Clinic staff
Complications of hemorrhoids are rare but include:
- Anemia. Chronic blood loss from hemorrhoids may cause anemia, in which you don't have enough healthy red blood cells to carry oxygen to your cells. This may result in fatigue and weakness.
- Strangulated hemorrhoid. If blood supply to an internal hemorrhoid is cut off, the hemorrhoid may be "strangulated," which can cause extreme pain and lead to tissue death (gangrene).
