During an anal fissure, it is possible to have sexual intercourse without any impact on the fissure itself. For patients with an anal fissure, the main focus should be on maintaining smooth bowel movements and avoiding dry and hard stools to prevent irritating the wound, which can cause pain and bleeding. It is also important to avoid diarrhea, as frequent bowel movements can irritate the wound over time and worsen the fissure. Clinically, for early-stage anal fissures, conservative treatment with medications is often recommended, along with softening the stool. Commonly used medications include Dragon Balm ointment or nitroglycerin ointment. After defecation, patients can opt to use an anal wash or a potassium permanganate solution for sitz baths. However, for chronic anal fissures, it is generally advised to undergo fissure excision surgery as soon as possible, followed by regular dressing changes to promote healing of the wound. If an anal fissure is left untreated for a long time, it can lead to slight narrowing of the anal canal, which requires significant attention.
