02 Mar WHAT ARE PILES?
Piles are swollen but normally present blood vessels in and around the anus and lower rectum that stretch under pressure. The increased pressure and swelling may result from straining to move the bowel. Other contributing factors include pregnancy, heredity, aging, and chronic constipation or diarrhea. Piles are either inside the anus (internal) or under the skin around the anus (external).
