Eating bananas after surgery should be evaluated according to the different surgical methods of patients:1. If patients undergo minor surgeries such as excision of body surface masses and drainage of abscesses, patients can eat bananas on the day of surgery.2. If patients undergo surgeries on limbs and bones, and the surgeries do not have any serious effects on the gastrointestinal tracts of the patients, patients can eat bananas on the second day of the surgeries, which is also conducive to the recovery of gastrointestinal function.3. If If the patient undergoes abdominal surgery, such as cholecystectomy, myomectomy, radical treatment of gastric cancer, etc., try to eat bananas and other fruits when the gastrointestinal function recovers, i.e., when the anal defecation and bowel movement are normal, which won’t increase the burden of the gastrointestinal tract and is conducive to the recovery of the patient’s condition.
