What are Piles (Hemorrhoids)?Piles are swollen or inflamed veins located in the lower part of your rectum and anus. They are quite common and similar to varicose veins that can occur in the legs.Types of Piles:Internal Piles:Located inside the rectum.Usually not visible or painful unless they become enlarged and prolapse (slip down and protrude outside the anus).The most common symptom is bright red, painless bleeding during or after a bowel movement (seen on toilet paper or in the bowl).External Piles:Located under the skin around the anus.Can cause itching, irritation, aching, or pain, especially when sitting.If a blood clot forms inside an external pile (thrombosed hemorrhoid), it can cause sudden, severe pain and a hard lump near the anus.Common Symptoms:Bright red blood on toilet paper, in the toilet bowl, or on the surface of stools.Itching, irritation, or swelling around the anus.Pain or discomfort, particularly when sitting (more common with external or thrombosed piles).A lump or swelling near the anus (can be sensitive or painful).Mucus discharge after a bowel movement.Feeling that the bowel hasn't emptied completely.Common Causes & Risk Factors:Piles develop due to increased pressure in the lower rectum. Factors contributing to this include:Straining during bowel movements: Often due to constipation.Chronic constipation or diarrhea: Both can lead to straining or irritation.Sitting for long periods: Especially on the toilet.Pregnancy: Due to hormonal changes and increased pressure from the uterus.Obesity: Increases pressure in the abdominal and pelvic region.Low-fiber diet: Can contribute to constipation.Aging: Tissues supporting the veins can weaken.Heavy lifting: Regularly lifting heavy objects.
