Anal fissures are prone to recurrence, and the main reasons for recurrence are prolonged sitting or standing, leading to relaxation of the intestinal muscles and insufficient motility, which can cause constipation. During bowel movements, the damaged area can be scratched, resulting in anal fissures. Due to excessive strain, mental stress, and physical fatigue, metabolism can be affected, leading to indigestion and constipation, which can cause anal fissures. Sometimes irregular eating habits and consuming spicy, greasy, and irritating foods can cause constipation, thus aggravating the fissure and leading to its recurrence. An imbalance in intestinal flora can impair digestion and cause constipation, leading to anal fissures. The fundamental treatment for anal fissures is surgical intervention.
