Piles, also known as hemorrhoids, are swollen veins and muscle around your anus or in your anal canal. Your anal canal is a short, muscular tube with blood vessels that connects your rectum (back passage) with your anus. Piles can develop when this tissue around the rectal vain becomes swollen, possibly as a result of straining on the toilet. Sometimes, piles can be painful and bleed if the rectal vain get ruptured.
Piles are also common during and after pregnancy. They may develop due to changes in the hormones (chemicals) in your body and the increased pressure in your abdomen (tummy). They usually get better once the baby is born.
You can get piles at any age, but they’re most common in people aged between 45 and 65. It’s difficult to know exactly how many people get piles
