The inside layer of the anal canal enclosed three soft, flexible and spongy pads of tissue that perform as an extra seal to keep the canal blocked until you go to the lavatory. The coating of the gut is very oily (thatís why faeces can go by very easily); the extra seal stops the substance (mucus) from over flow. The pads have an arrangement of small blood vessels. When a person is suffering from piles, the veins in the anus area are become inflamed and bleed. Piles are also known as hemorrhoids, and it should not be mystified with fissures.
There are three main types of piles
Internal piles occur when the piles influence the inner region of the anus and it causes bleeding.
In cases of external piles, the affected part can be visible and one can also feel it on the outer surface of the anus. External piles can be aching but it does not cause excess of bleeding. They can be more painful than the other types of piles.
Usually, persons get piles that are a mixture of internal and external piles.
As a pile is one of the spongy pads that have slipped downwards somewhat, as the nearby tissue is not holding it in position correctly. When this occurs, the small blood vessels inside the pad become inflamed with blood, so the pad swells up. When faeces are passed, the pile may be pressed further down the anal tube to the outside, and this is called a prolapsed pile.
