Other factors include diet, overuse of laxatives, inflammation or infection of the rectal area, heredity, and other problems of the rectum.
Hemorrhoids are a very common problem.
It is not known exactly how many people have them, because often they do not cause symptoms. We do know that the largest number of symptoms from hemorrhoids occur in people between the ages of 20 and 50. Pain, itching, and bleeding are common symptoms. Hemorrhoids inside the rectal opening are usually painless, but often bleed and cause a feeling of fullness, which may cause an urge to have a bowel movement even when there is no stool present. Straining to have a bowel movement can aggravate the problem.
