Hemorrhoids are present in healthy individuals. In fact, hemorrhoidal columns exist in utero. When these vascular cushions produce symptoms, they are referred to as hemorrhoids. Hemorrhoids generally cause symptoms when they become enlarged, inflamed, thrombosed, or prolapsed.
Most authors agree that low-fiber diets cause small-caliber stools, which result in straining during defecation. This increased pressure causes engorgement of the hemorrhoids, possibly by interfering with venous return. Pregnancy and abnormally high tension of the internal sphincter muscle can also cause
hemorrhoidal problems, presumably by means of the same mechanism.
Decreased venous return is thought to be the mechanism of action. Prolonged sitting on a toilet (eg, while reading) is believed to cause a relative venous return problem in the perianal area (a tourniquet effect), resulting in enlarged hemorrhoids. Aging causes weakening of the support structures, which facilitates prolapse. Weakening of support structures can occur as early as the third decade of life. Straining and constipation have long been thought of as culprits in the formation of hemorrhoids
