PilesHemorrhoids are nothing more than enlarged veins. When they occur in the lower legs, we call them varicose veins. When they occur in the rectum, they are called hemorrhoids or "piles." Hemorrhoids or hemorrhoidal veins are essentially normal parts of the anorectal area. It is only when they become symptomatic that they cause a problem Hemorrhoids are blood vessels like mesh nets around the anus and the lower edge of the rectum. The main body of hemorrhoids is the wens which swelled up into a wen condition (varices). 
The actual anal opening is also known as the anal verge. Approximately 2-3 cm above the anal verge is an anatomic landmark known as the dentate or pectinate line. This is distinguished by a circular row of glands that secrete mucus, which acts to lubricate the anal canal. Groups of normal submucosal vascular beds composed of supportive connective tissue, smooth muscle and blood vessels surround the anal canal. When these beds enlarge, the result is hemorrhoids. Those who support the straining theory assert that straining interrupts the tissues that support the vascular bundles, displacing the tissues and leading to their congestion. |
