There is no significant restriction in the diet after inguinal hernia surgery for tension-free repair of inguinal hernia in principle. Since patients with postoperative inguinal hernia need to be bedridden for a period of time, their activity is significantly less than usual, especially in older patients, it is recommended that after hernia surgery, especially within 48 hours, patients should try to eat a light and easily digestible diet, not to drink alcohol, and not to eat hard, cold or spicy food. Seventy-two hours after surgery, the patient can return to the same normal diet as before surgery, but still cannot drink alcohol, otherwise there are no special restrictions.
