Hemorrhoids Topic Guide

Hemorrhoids are large veins in the rectum that cause pain. Causes of hemorrhoids include constipation, straining during a bowel movement, low-fiber diet, and liver disease. Symptoms of internal hemorrhoids are usually painless. External or prolapsed internal hemorrhoid symptoms and signs may include:

• Pain
• A lump outside the anus
• Anal itching
• Constant urge to have a bowel movement
• Blood with a bowel movement

There are a variety of over-the-counter treatments for hemorrhoids. Some do not resolve on their own so surgery is necessary.
