When a hemorrhoid forms it is known as piles. Piles or haemorrhoids are swollen veins. This form of swelling can lead to localized inflammation of the other tissues, leading to extreme discomfort.

Talking about the types of haemorrhoids, there are internal and external haemorrhoids. An internal haemorrhoid takes form when the veins within swell up. They can arise due to various reasons. External piles form small lumps on the affected part’s outside edge. They are extremely itchy. They can even be painful upon the formation of a blood clot.

Dr Amita Jain, one of the best piles surgeons in Delhi in the field of laparoscopic surgery talks about the 4 stages of piles.

Stage 1: First-degree haemorrhoids

In this stage, the haemorrhoids are internal and generally not visible. They might cause minimal symptoms, like mild itching or discomfort, but typically do not cause pain. They might occasionally bleed during bowel movements.

Stage 2: Second-degree haemorrhoids

At this stage, the haemorrhoids become larger and might prolapse (protrude) during bowel movements, but retract back into the affected part on their own. They may cause more significant symptoms, including itching, pain, and bleeding. However, the symptoms generally resolve after the prolapsed haemorrhoids are reduced.

Stage 3: Third-degree haemorrhoids

Third-degree haemorrhoids are larger and more prolapsed compared to second-degree haemorrhoids. They typically need manual repositioning, meaning they do not retract back into the on their own. Symptoms are more pronounced and might include bleeding, itching, pain, and discomfort.

Stage 4: Fourth-degree haemorrhoids

This is the most severe stage of haemorrhoids. Fourth-degree haemorrhoids are permanently prolapsed and are not manually repositioned. They might cause significant pain, bleeding, itching, and discomfort. In certain cases, a blood clot (thrombosis) can develop within the prolapsed haemorrhoids, leading to extreme pain and swelling.......
