Hemorrhoids

The causes of hemorrhoids include genetic predisposition (weak rectal vein walls and/or valves), straining during bowel movements, and too much pressure on the rectal veins due to poor muscle tone or poor posture. Hemorrhoids may also result from portal hypertension because of the portacaval anastomoses. Hemorroids are also linked to sitting for prolonged periods of time.Additional factors that can influence the course of hemorrhoids (mostly by increasing rectal vein pressure), especially for those with a genetic predisposition, are obesity and a sedentary lifestyle. Constipation, chronic diarrhea, poor bathroom habits, pregnancy, postponing bowel movements, and fiber-deprived diet may be associated with bowel movement and straining, but not all of these have been conclusively proved to cause hemorrhoids.

Prevention of hemorrhoids

Prevention of hemorrhoids includes drinking more fluids, eating more dietary fiber, exercising, practicing better posture, and reducing bowel movement strain and time. Hemorrhoid sufferers should avoid using laxatives and should strictly limit time straining during bowel movement. Wearing tight clothing and underwear will also contribute to irritation and poor muscle tone in the region and promote hemorrhoid development. Some sufferers report a more comfortable experience without underwear or wearing only very lightweight panties, etc.

Straining can be lessened by defecating in a standing position, knees slightly bent. This position seems to use the muscles of the abdomen to expel feces preventing a strain on the anus. Fluids emitted by the intestinal tract may contain irritants that may increase the fissures associated with hemorrhoids. Washing the anus with cool water and soap may reduce the swelling and increase blood supply for quicker healing and may remove irritating fluid.
