Types

Depending upon the site of formation, piles (hemorrhoids) can be divided into two types:

  • External piles(hemorrhoids): These develop at the margins of the anal opening and can be seen outside (hence known as external piles). These are usually painful and may rupture and bleed especially due to the passage of hard stools eroding the already dilated blood vessels. The external piles (hemorrhoids) may also become thrombosed (presence of blood clot) and are felt as a small, painful lump around the anal opening.
  • Internal piles (hemorrhoids): These develop inside the anus. They are usually painless but sometimes may cause a vague discomfort. Slight bleeding may be seen especially if the stools are hard. These piles (hemorrhoids) have a tendency to bulge out of the anal opening when they appear like a bunch of grapes, which is painful. When both the external and internal varieties are associated it is called interoexternal piles(hemorrhoids).
