Piles can be of various sizes and may be internal (inside the anus) or external ones (outside the anus). Typically, internal piles occur from 2 to 4cm above the opening of the anus. External piles (perianal hematoma) occur on the outside edge of the anus. The internal ones are much more common.
According to the US National Institutes of Health (NIH), symptomatic hemorrhoids affect at least half the American population at some time in their lives before the age of 50. In the majority of cases, piles are effectively treated with over-the-counter medications, a good fluid intake, and by following a diet high in fiber. In severe cases, the piles may have to be surgically removed. About 10% of patients who go and see their doctor about piles eventually require surgical intervention.
Symptoms of piles
In most cases piles are not serious and go away on their own after a few days.5 An individual with piles may experience the following symptoms:
• A hard lump may be felt around the anus. It consists of coagulated blood, called a thrombosed external hemorrhoid. This can be painful
• After going to the toilet, a feeling that the bowels are still full
• Bright red blood after a bowel movement
• Itchiness around the anus
• Mucus discharge when emptying the bowels
• Pain while defecating
