Piles: Causes, Symptoms & Risk Factors

Piles or inflamed hemorrhoids are basically lumps found in rectum or around the anal canal that are full of blood vessels, support tissue, muscle and elastic fibers, which have become swollen and engorged. It is first noticed with the appearance of blood in stools.

Piles can be of various sizes and may be found internally 2-4 cm above the opening of the anus or externally on the outside edge of the anus.


There may be multiple causes for piles and these may cause blood vessels around the anus to stretch under pressure which may then swell or bulge. Inflammation of veins usually happens when there is an increased pressure in the lower rectum. This may be due to:
– Lack of fiber in the diet
– Consumption of highly processed food
– Chronic constipation
– Chronic diarrhea
– Lifting heavy weight
– Pregnancy
– Straining when passing a stool

Piles usually get resolved on their own, but it may be a bad experience till the time they last.

In most cases patients suffering from piles may face the following symptoms:

  • Constant pain while passing stools
  • Presence of mucus discharge and blood in the stools
  • Feeling of fullness even after defecating and going to the toilet
  • Feeling of a hard lump around the anus, this may be due to presence of coagulated blood, and can be very painful
  • Bright red blood after a bowel movement
  • Itchiness around the anus
  • Area around the anus may be red and sore

Risk factors:

  • Chronic constipation and diarrhea
  • Excessive straining leads to piles
  • Obesity and being overweight
  • Lifting of heavy objects on regular basis
  • Sedentary lifestyle with long sitting hours
  • Pregnancy poses as one of the major risk factors for piles because growth of the baby puts pressure on the pelvis and may lead to enlargement of the anal and rectal blood vessels and consequent development of piles. These piles however, disappear with child-birth
