Grade 1: Haemorrhoids remain inside the rectum and do not protrude. They may cause painless bleeding but usually have no visible symptoms.
Grade 2: These haemorrhoids may prolapse (push out of the anus) during bowel movements but return inside on their own. Symptoms can include mild discomfort and bleeding.
Grade 3: Haemorrhoids prolapse outside the anus and do not return on their own. They need to be manually pushed back in and may cause significant discomfort, irritation, and bleeding.
Grade 4: These are permanently prolapsed haemorrhoids that cannot be pushed back inside. They can cause severe pain, swelling, and complications, often requiring medical intervention or surgery.
Non-Thrombosed External Haemorrhoids
Thrombosed External Haemorrhoids
Chronic Constipation or Diarrhea – Straining during constipation or frequent bowel movements from diarrhea puts excessive pressure on the rectal veins. Pregnancy – Increased abdominal pressure during pregnancy can cause veins in the rectum to swell. Aging – As the body ages, the tissues supporting the rectal veins weaken, making piles more likely
Prolonged Sitting – Sitting for extended periods, especially on the toilet, can worsen pressure on anal veins. Heavy Lifting – Frequent lifting of heavy objects can increase strain on the lower rectum. Low-Fiber Diet – A diet lacking fiber can lead to hard stools and difficulty passing bowel movements
Liver Disease – Liver conditions can increase blood pressure in the veins, leading to hemorrhoids. Inflammatory Bowel Disease (IBD) – Chronic conditions like Crohn’s disease or ulcerative colitis can cause irritation and swelling in the rectal area.
