What are the risk factors for hemorrhoids?

Pregnancy increases the risk of hemorrhoids, as does chronic constipation and chronic diarrhea. Hemorrhoids tend to run in families, and the risk increases with age.

Hemorrhoids are caused by repeated pressure and strain. Certain conditions may cause internal hemorrhoids to bulge, become irritated, and bleed, including:

• Diarrhea (frequent, loose, watery stool)

• Cirrhosis of the liver (can cause pooling of blood in the vessels around the rectum)
