Whether patients can eat potatoes after surgery should be analyzed according to the specific surgical methods and the recovery of gastrointestinal function.1. If patients’ surgical traumas are small and do not affect gastrointestinal function, such as incision and drainage of superficial abscess and resection of benign body mass, then patients’ gastrointestinal function recovers well after surgery and can eat potatoes.2. If patients’ surgical traumas are large and gastrointestinal function does not recover completely after surgery, such as radical treatment of gastric malignant tumor, then it is not recommended to eat potatoes after surgery to avoid aggravating the symptoms of abdominal pain and bloating. If the patient’s surgery is more traumatic and the gastrointestinal function is not fully recovered after surgery, such as gastric cancer radical treatment for gastric malignant tumors, it is not recommended to eat potatoes after surgery, so as not to aggravate the symptoms of abdominal pain and bloating. If the patient is in coma after surgery, it is not recommended to eat potatoes after surgery, so as not to aggravate the symptoms of abdominal pain and bloating, but the patient can eat potatoes in a small amount in 2-3 weeks after the full recovery of the condition, which is safer.3. If the patient is in coma after surgery, it is possible that the food may enter into the windpipe, inducing the choking and other serious complications, so it is not recommended to eat potatoes at this time either.
