After having anal fissure surgery, more stools are usually caused by the wound not healing, inflammation stimulation, anal sphincter damage and other reasons. 1. The wound is not healed: the wound is not healed, which will cause the wound to stimulate the anus, thus the pain around the anus occurs. At the same time, the patient’s wound is not healed after the operation, which will also have low immunity, resulting in intestinal flora disorders, and causing the symptom of heavy stools. 2. Inflammatory stimulation: postoperative inflammatory stimulation will lead to accelerated intestinal peristalsis, resulting in excessive bowel movements after anal fissure surgery. 3. Anal sphincter damage: anal fissure surgery may damage the patient’s anal sphincter, resulting in decreased stool storage function, resulting in postoperative anal sphincter contraction function is reduced, the symptoms of increased defecation. It is recommended that patients go to the hospital in time for examination, observe the physical condition, treat the symptoms under the guidance of the doctor, and do a good job of perianal hygiene care.
