Haemorrhoids

Haemorrhoids, or piles, are swollen veins or groups of veins in the region of the anus. The swelling occurs in the haemorrhoidal plexus and may be aggravated by inflammation, local clotting of the blood in a part of the circulatory system, or bleeding. The condition is very common, and piles can be classified either as external or internal.

Piles are more prevalent in old age and during pregnancy, and also occur following prolonged constipation and after excessive straining when passing a stool. They are often asymptomatic, but may present with rectal bleeding, protrusion of a blood vessel, or pain. Bleeding most often occurs after passing a stool. Haemorrhoids are associated with increased pressure exerted by liquids at rest in the portal venous system and even result from cirrhosis, a chronic disease of the liver marked by degeneration of cells, inflammation and thickening of tissue.
