External hemorrhoids are superficial varicose veins located just outside the opening of the anus.
Internal hemorrhoids are located higher up inside the rectum and most individuals may not even be aware of their presence. These internal hemorrhoids can be pushed outside the rectum by increasing pressure in this area during a bowel movement, pregnancy or childbirth. As pregnancy progresses, pressure on the rectum and lower colon becomes increased due to the enlarging uterus. This pressure often results in constipation and hemorrhoids. Alternative therapies are an appropriate first step in the treatment of hemorrhoids.
