Can a mild anal fissure heal on its own?

Minor anal fissures can heal on their own. Patients should maintain cleanliness of the anal area in daily life and avoid consuming spicy foods. Additionally, they should follow a light diet, drink plenty of water, and consume more vegetables and fruits rich in crude fiber, such as celery, wax gourd, and apples, to ensure smooth bowel movements and avoid irritating the anus. After each bowel movement, the anal area should be cleaned with warm water or wet wipes to prevent bacterial infection.
