Piles

Hemorrhoids, usually known as piles, are caused due to swollen veins around the anus or in the lower rectum. They are commonly caused by straining while having a bowel movement, pregnancy, colon cancer, constipation, or chronic diarrhoea. In most of the cases, piles resolve on their own by simple lifestyle modifications. But the patients who are distressed due to large, swollen and prolapsed pile may have to be treated with surgery.
