Causes and Risks

Hemorrhoids are caused by increased pressure in the veins of the anus. The most common cause is straining during bowel movements. Constipation, prolonged sitting during bowel movements, and anal infection are contributing factors. Internal hemorrhoids occur near the beginning of the anal canal, and external hemorrhoids occur at the anal opening. Hemorrhoids may protrude outside the anus. They are very common, especially during pregnancy and after childbirth.The incidence is 2 out of 1000 people.
