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.
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.
