What Causes Internal Hemorrhoids
Hemorrhoids, the swollen veins that can develop in the rectum and anus, are a common occurrence. By age 50, half of adults have had to deal with hemorrhoids, according to the MayoClinic.com. Hemorrhoids may cause painless bleeding during bowel movements, itching and irritation, swelling, pain and discomfort around the anus. Hemorrhoids occur due to increased pressure on the veins, and several conditions can cause internal hemorrhoids.
