If piles (hemorrhoids) are not controlled or treated on time they can lead to complications. These may include:
- Profuse hemorrhage (bleeding) frequently occurs in the early stages of the second degree piles (hemorrhoids).
- Strangulation or gripping is most often seen in second degree piles (hemorrhoids), when the internal piles (hemorrhoids) are gripped by the anal sphincter (external opening of the anus) leading to further congestion in veins. It is a very painful condition.
- Thrombosis (blood clotting): If the internal piles (hemorrhoids)continue to be strangulated for long time it gets thrombosed and the color changes to purple or black. Even though the pain of strangulation passes off tenderness (pain on pressure) remains.
- Ulceration (open sore): The thrombosed piles (hemorrhoids) may ulcerate.
- Gangrene (decomposition of body tissue either by obstructed circulation or infection): Strangulation may eventually cut off the blood supply leading to the death of tissue (known as gangrene).
- Fibrosis: After thrombosis the piles (hemorrhoids) may convert into scar tissue (fibrosis).
- Suppuration: Rarely the thrombosed piles (hemorrhoids) may get infected (filled with pus).
