What should I do if an anal fissure does not heal?

Anal fissure is a common anorectal disease, typically presenting with symptoms such as anal pain and bleeding during defecation. Failure of an anal fissure to heal is a complex issue that may be caused by various factors, including constipation, dietary irritants, and local infection.

Patients are advised to seek timely medical evaluation to rule out other diseases that may cause similar symptoms. In daily life, patients should increase their dietary fiber intake, drink more water, maintain regular bowel movements, and avoid both constipation and diarrhea. Developing a habit of defecating at regular intervals, avoiding stool retention and excessive straining during bowel movements, maintaining anal hygiene, and avoiding aggressive wiping are recommended; the use of warm water cleansing or moist wipes may be beneficial. If the anal fissure is severe, does not respond adequately to the aforementioned conservative treatments, or recurs frequently leading to chronic ulcers, surgical intervention should be considered.
