WHAT HAPPENS IN PILES (hemorrhoids)

Veins collects blood from different parts of the body, and move towards the heart against the gravity. To avoid back flow of blood, stoppers are placed in the vein at different places, which are known as valves. But around the anal region, these valves are not present in the veins (rectal).

So, whenever the pressure in the vein (rectal) increases, which can be due to excessive straining, the engorgement or dilatation of the vein occurs. Engorged vein starts to push the anal lining downwards as a result of gravity and causing the prolapse of anal lining. This protrusion of the anal lining forms the Haemorrhoids or Piles.
