Dietary restrictions can play an important role in healing anal fissures. To avoid potential triggers and manage pain, specialist proctologists recommend avoiding certain foods that are known to cause irritation such as spicy food, nuts, popcorn, carbonated beverages, and alcohol.   In addition, consuming more fiber-rich foods like fruits and vegetables is encouraged to help soften stools which will reduce the strain of passing them. It may also be beneficial to increase water intake to prevent dehydration which could contribute to constipation.   Following these dietary recommendations should provide relief while recovering from an anal fissure.
