Piles, also known as hemorrhoids, are swollen veins in and around the anal area. There are different types of piles based on their location and severity. Internal piles develop inside the rectum and usually cause painless bleeding. External piles form outside the anus and may lead to pain, itching, and swelling. Bleeding piles are identified by blood during bowel movements and should not be ignored. Thrombosed piles occur when blood clots form, causing severe pain and inflammation. Understanding the types of piles helps in early diagnosis and choosing the right treatment for long-term relief.
