Pubic hair shaving is generally required for hernia surgery. Hernias are close to the pubic area, so if the pubic hair is long or thick, it may interfere with the surgical operation and affect the postoperative result, so it is generally required to clean and care for the surgical area and shave off the pubic hair before the operation. Before hernia surgery, shaving off the pubic hair can expose the entire surgical area, which can prevent secondary infections from occurring locally during the surgical operation, as well as identify the exact location of the hernia more clearly, so as to facilitate a better completion of the surgery. On the first day of hernia surgery, the diet should be as light, nutritious and easy to digest as possible, and no food is allowed to be eaten after 12:00 pm on the first day of surgery. It is advisable to consult your doctor if you have any questions before the surgery, or if you experience any discomfort.
