The first time you have a bowel movement after hemorrhoid surgery, you will experience pain, which is usually normal. The increase in pain during defecation is due to two main reasons: first, the wound needs to heal slowly after hemorrhoid surgery, and during the healing process, scarring is formed on the wound, which can easily cause anal stenosis. Secondly, hemorrhoid surgery forms a wound in the skin around the anus, and when defecating after surgery, the wound is not completely healed and is stimulated by feces and intestinal fluids, which can easily cause increased pain and even bleeding. Although there will be painful defecation after hemorrhoid surgery, patients should insist on defecating because this can serve the purpose of anal dilation to a certain extent.
