More recent studies show that patients with hemorrhoids tend to have a higher resting anal canal tone - that is, the smooth muscle of the anal canal tends to be tighter than average (even when not straining). This also explains why hemorrhoids are common during pregnancy, when the enlarging uterus presses on the veins. Traditionally, hemorrhoids are associated with chronic constipation, straining during bowel movements, and prolonged sitting on the toilet - all of which interfere with blood flow to and from the area, causing it to pool and enlarge the vessels. Hemorrhoids are distended blood vessels that form either externally (around the anus) or internally (in the lower rectum). Wiping constantly to try to relieve the itching can worsen the problem. When a hemorrhoid protrudes, it can collect small amounts of mucus and tiny stool particles that may cause an irritation called pruritus ani. Internal hemorrhoids may also prolapse, or extend beyond the anus, causing several potential problems. You might, for example, see bright red blood on the toilet paper or dripping into the toilet bowl. Internal hemorrhoids are typically painless, even when they produce bleeding. The clot usually dissolves, leaving excess skin (a skin tag), which may itch or become irritated. You might feel or see a lump around the anus. If a blood clot forms inside an external hemorrhoid, the pain can be sudden and severe. External hemorrhoids are the most uncomfortable, because the overlying skin becomes irritated and erodes. There are two kinds of hemorrhoids: internal hemorrhoids, which occur in the lower rectum, and external hemorrhoids, which develop under the skin around the anus. Because the blood vessels involved must continually battle gravity to get blood back up to the heart, some people believe hemorrhoids are part of the price we pay for being upright creatures. The condition most of us call hemorrhoids (or piles) develops when those veins become swollen and distended, like varicose veins in the legs. In one sense, everyone has hemorrhoids (or piles), the pillow-like clusters of veins that lie just beneath the mucous membranes lining the lowest part of the rectum and the anus. Fortunately, there's a lot we can do about hemorrhoids. Although hemorrhoids are rarely dangerous, they can be a recurrent and painful intrusion. By age 50, about half the population has experienced one or more of the classic symptoms, which include rectal pain, itching, bleeding, and possibly prolapse (hemorrhoids that protrude through the anal canal). By midlife, hemorrhoids often become an ongoing complaint. Hemorrhoids are usually caused by increased pressure due to pregnancy, being overweight, or straining during bowel movements.
