Hemorrhoids

Overview of Hemorrhoids

Hemorrhoids are dilated veins, or varicose veins, located inside of the anal canal (internal hemorrhoids), or at the anal opening (external hemorrhoids). Hemorrhoids may be undetected until bleeding occurs and may be present for years.

Causes of Hemorrhoids

Increased pressure in the veins produces hemorrhoids. The veins may become enlarged during a bowel movement. Pregnancy, may raise the pressure in these veins.

Signs and Symptoms of Hemorrhoids

Hemorrhoids produce rectal bleeding, rectal pain and rectal itching. There may be blood on the stool and there may be a mucus discharge after bowel movements. A lump may be felt in the anus. Sometimes, there is the sensation that the rectum has not emptied completely after a bowel movement. This is usually seen with large hemorrhoids only. There is often inflammation and swelling of the rectal tissue.
