Hemorrhoids, also known as piles, are swollen and inflamed veins in the rectum and anus. They commonly occur in adults aged 40-60 years old. Symptoms include painless bleeding during bowel movements, itching or irritation in the anal region, and swelling around the anus. Treatment options include banding, sclerotherapy, laser therapy, creams and suppositories for mild cases. Lifestyle changes such as a high fiber diet, drinking plenty of fluids, exercise, and proper hygiene can help prevent hemorrhoids.
