Piles, also called hemorrhoids, are swelling and inflamed veins that are located in the anus and rectum. They are caused by an increase in tension in the lower part of the rectum which may result from the strain of bowel movements or constipation due to obesity, and many other causes. Piles are a very common disease that affects around 50 percent of people at one time throughout their life. Pile symptoms can include itching or pain around the anus, bleeding from the rectal and a lump in the vicinity of the anus which can be felt or observed. Although piles can be uncomfortable but most cases are managed effectively through lifestyle modifications and prescription medications. In extreme instances, more aggressive treatment like surgery might be required.
