Experts are divided on exactly what causes hemorrhoids, but probably several mechanisms are at work. 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. This also explains why hemorrhoids are common during pregnancy, when the enlarging uterus presses on the veins.
