Piles are the tortuous veins which bulge out in the anal canal. There are so many factors responsible for this engorgement of the anal veins. The most common cause is chronic constipation. In such condition patients have to strain for defecation which puts pressure on the veins leading to congestion & engorgement. When these veins get ruptured by passing hard stools or due to straining it initiates characteristic painless bleeding. Bleeding may be in the form of fresh blood drops or spurts of fresh blood. At this stage bleeding is the only symptom that patients complain of, This is known as 1st degree hemorrhoid. When these congested rectal veins increase in size, the pile mass may protrude out during defecation. After passing stool, the pile mass reduces by itself and some times patients have to reduce the pile mass manually. This stage is labelled as 2nd degree piles. When these pile masses further increase in size they may protrude out during walking or sitting etc this is known as third degree piles.
