Enlarged hemorrhoids are directly caused by higher pressure in the anal sphincter, the hemorrhoids themselves and in the muscles that are surrounding the anal canal. The anal sphincter is the muscle that gives us control over bowel movements. It has not yet been determined if the pressure comes before the hemorrhoids or if the hemorrhoids create the higher pressure. If the higher presure does come before the hemorrhoids, it may be the direct reason why there is more pressure in the anal canal. This would continually create force from the stools against the walls of the anl canal. Hemorrhoid causes may also be related to a genetic predisposition. It would be highly probable that it has been passed down from a family member if it has been in the family. The predisposition could be having weak walls or veins in the rectal area. It is also believed that because humans are always erect, there is continual gravitational force of blood pressure down to the rectal area. People are always standing or sitting enabling the formation of hemorrhoids to be more prevelant. Click here to for the best
