Generally, anal fissures that occur postpartum may heal on their own within about a week. For more severe cases, timely surgical treatment is necessary. The specific recovery time also depends on the physical condition of the mother, such as nutritional status, diet, and everyday habits—whether her diet is balanced, whether she drinks enough water, etc., all of which can affect the recovery and progression of the condition. If postpartum women improve their diet by eating more fresh vegetables and fruits, drinking more soups, and developing regular bowel habits to alleviate constipation, the anal fissures can also improve on their own.
