Q: Is it dangerous to have hemorrhoids? A: Hemorrhoids are generally not dangerous, but its hazards should not be ignored. The most important symptoms of hemorrhoids are blood in the stool and prolapse. Repeated bleeding during stool can cause iron deficiency anemia due to chronic blood loss that makes the body lose a lot of iron. Another major symptom of hemorrhoids is the prolapse of internal hemorrhoids. Internal hemorrhoids that are prolapsed outside the anus can become infected or necrotic, requiring surgery and even serious complications. Therefore, it is still important to treat and deal with hemorrhoids early.
