Piles
Pile disease, also known as haemorrhoids, is characterised by the development of swellings within and around the back passage (anal canal). Within the lining of the anal canal is a web-like structure made up of numerous tiny veins, which are blood vessels. On occasion, these veins will expand and fill up with a greater volume of blood than is typical for them. After that, one or more swellings may develop as a result of the engorged veins and the surrounding tissue (piles). Pile is a medical term that refers to a collection of tissue and vein that has become swollen and inflamed. Piles can be found either within or outside the anus, and their size can range from very small to very large. Piles occur due to chronic constipation, chronic diarrhoea, lifting heavy weights, pregnancy, or straining when passing a stool.
