The following are some of the reasons why post-operative hemorrhoid surgery patients have unformed stools: 1. The stimulation of the surgical incision itself will lead to an increase in the number of bowel movements, which will lead to unformed stools and even loose stools; 2. Post-operative hemorrhoid patients are mainly liquid and semi-liquid at the beginning, and the change in diet structure is also a major cause of unformed stools; 3. The change of habits is also a cause of unformed stools. After hemorrhoid surgery, it is advisable to eat more vegetables, fruits, cereals and other coarse fiber food, avoid eating spicy and stimulating food, usually keep the stool soft and fluent, pay attention to the cleaning and disinfection of the anal incision after the stool, and go to the hospital regularly to follow up on the healing of the incision.
