In general, fissures lasting less than 6 ~ 8 weeks are considered acute anal fissures, while those persisting longer are classified as chronic anal fissures (CAF).

Core Treatment: Reducing Anal Muscle Tension

The primary treatment goal is to relax the anal sphincter and relieve pain. Along with lifestyle modifications such as quitting smoking, regular exercise, and adequate rest, the most important step is to prevent constipation :

• Drink plenty of water
• Eat a high-fiber diet (fruits, vegetables, whole grains)
• Use stool softeners when necessary

If lifestyle adjustments alone are insufficient, the American Society of Colon and Rectal Surgeons recommend medication therapy. Current drug options are generally safe and well-tolerated, with minimal side effects. However, a study published in the Journal of Visceral Surgery (2015) found that the use of local anesthetics, vitamins, or anti-inflammatory agents did not provide benefits superior to simple lubricants.

Wound Care: MOISTURE AND PROTECTION ARE KEY
