Piles are abnormally enlarged and dilated blood vessels ( mainly veins) around the back passage or anus. Piles are also known as "hemorrhoids". Hemorrhoids occur in both men and women most often between the ages of 20 and 50.

Causes of Piles

It can be hereditary with congenital weakness of the vein walls.
In men, due to erect posture there is high pressure in rectal veins.
Straining by constipation and over purgation.
Dysentery may aggravate latent hemorrhoids.
Haemorrhoids are also common among pregnant women. The pressure of the foetus in the abdomen, as well as hormonal changes, cause the haemorrhoidal vessels to enlarge.
