Piles (haemorrhoids) are swellings that can occur inside and around the back passage (anus) and the anal canal.
The anal canal is the last part of the large intestine and is about 4 cm long. At the lower end of the anal canal is the opening to the outside (usually referred to as the anus), through which faeces pass. At the upper end, the anal canal connects with the rectum (also part of the large intestine).
There is a network of small veins (blood vessels) within the lining of the anal canal. These veins sometimes become wider and engorged with more blood than usual. The engorged veins and the overlying tissue may then form into one or more small swellings called piles.
