whats the causes of pile?

Answer 1

There are multiple causes of piles or haemorrhoids.
Anything which puts strain on the blood vessells in and around the rectum and or anus can cause them- some unlucky people are genetically prone to them (varicous veins/incompetence)runs in the family.
Factors which predispose to them are: Childbirth and pregnancy,constipation and straining on going to the loo, sitting on heated areas for prolonged periods(ie radiators),poor diet,obesity and anal intercourse, spending prologed periods sitting on the toilet- do your business and leave!!Dont read for half an hour

Answer 2

Are you referring to hemorrhoids which are dilated, twisted veins located in the wall of the rectum and anus? Anything that puts pressure on these veins is a cause for hemorrhoids; i.e. heavy lifting, pregnacy/childbirth, constipation, extended sitting (truck drivers). A less frequent cause is increased blood pressure in the portal vein. A doctor can distinguish the dilated, twisted veins that occur in this condition from common hemorrhoids.
