Large Hemroids 

What are Piles (hemroids) ?
Hemroids has been derived from a Greek word 'haima' meaning blood and 'rhoos' meaning flowing. Each of us have veins around the anus that tend to stretch under pressure. An increased pressure within the abdomen (due to repeated straining at stool, pressure of fetus during pregnancy, obesity etc.) may cause blood to stagnate and collect in the blood vessels causing them to swell and bulge out of the anal opening (opening through which stool passes). These swollen veins are called piles or hemroids.
