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 ( poo ) 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.
Piles can be of various sizes and may be internal (inside the anus) or external ones (outside the anus). Typically, internal piles occur from 2 to 4cm above the opening of the anus. External piles (perianal hematoma) occur on the outside edge of the anus.
Internal piles (haemorrhoids) are those that form above a point 2-3 cm inside the back passage (anus) in the upper part of the anal canal. Internal piles are usually painless because the upper anal canal has no pain nerve fibres. External piles are those that form below that point, in the lower part of the anal canal. External piles may be painful because the lower part of the anal canal has lots of pain nerve fibres

6. Drink plenty of fluids.
7. After you have passed the faeces, do not strain to finish.
8. People with piles often think there is more to come, but this is a false sensation caused by the swollen spongy pads in the piles themselves.
