There are several possible causes of haemorrhoids, but they are typically related to constipation, prolonged sitting on the toilet, and straining during bowel movements. These conditions also cause blood vessels to become enlarged, preventing proper blood flow. This can cause haemorrhoids to form under the anus or inside the anal canal. While they are usually painless, they can also lead to severe complications and require surgery.

Symptoms of piles include pain and discomfort when sitting or wiping, as well as bleeding from the rectum. You may also experience bleeding when wiping, dizziness, or fainting. If these symptoms do not improve, you should schedule an appointment with a specialist. A haemorrhoid may be severe, resulting in thromboses haemorrhoids or a colostomy.
