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.



Around the anus, you might feel a lump that is firm and possibly painful. It may contain coagulated blood. External haemorrhoids that have become thrombosed are referred to as piles that contain blood.

A person who suffers from piles may have the sensation that their bowels are still full after they have already passed a stool.

Following a bowel movement, there may be visible blood that is a bright red colour.

The skin in the region surrounding the anus is irritated, red, and painful.

The passage of a stool is accompanied by the sensation of pain.

Excessive blood loss from the anogenital region, which may also result in anaemia.
