Whether patients can eat mutton after surgery for trauma is generally based on the specific location of the trauma and whether the gastrointestinal function is fully recovered after surgery. If a patient has a fracture of the lower limb caused by trauma and undergoes surgery for internal fixation, the gastrointestinal function of the patient is not significantly affected after surgery. Patients can eat mutton in moderation, which is rich in animal protein, due to the faster recovery of the patient’s condition. Second, if the patient’s liver rupture caused by trauma, emergency treatment of liver rupture repair surgery under general anesthesia, after surgery, gastrointestinal function is not fully restored exhaust and defecation, still accompanied by abdominal pain and bloating symptoms. At this time, the patient’s digestive ability is weak, if the patient eats more mutton, it will aggravate the abdominal pain and bloating symptoms, which is not conducive to the patient’s faster recovery. It is suggested that it is safer to eat mutton after the patient’s gastrointestinal function has fully recovered and the abdominal inflammation has completely subsided.
