Piles or Bavasir (in Hindi), a.k.a. hemorrhoids, are enlarged blood vessels that get developed around the anus or lower rectum, There are two types: Internal hemorrhoids and External hemorrhoids
Internal hemorrhoids form in the lining of the anus and lower rectum. Painless rectal bleeding or prolapse of anal tissue is often associated with symptomatic internal hemorrhoids. Internal hemorrhoids are classified by their degree of prolapse, which helps determine management:
Grade One: No prolapse
Grade Two: Prolapse that goes back in on its own
Grade Three: Prolapse that must be pushed back in by the patient
Grade Four: Prolapse that cannot be pushed back in by the patient (often very painful)
External piles are swellings that develop further down your anal canal, closer to your anus. They can be really painful, especially if they have a blood clot in them. The pain is usually constant and can be severe.
Mostly they are small, round, discoloured lumps, one can feel them on anus or hanging down from the rectum. Piles are very common in both men and women. About half of all people will have hemorrhoids by age 50.
