Gastric cancer progresses relatively rapidly and if it can be treated surgically, patients are advised to undergo surgical resection in a timely manner, which is the most effective treatment method at present. Patients need to pay extra attention to postoperative care when undergoing gastrectomy surgery. You should eat less and more meals, not overeating and binge eating. You can eat foods that are easy to digest and absorb, such as rice porridge, noodles, rice paste, etc. Avoid foods that can easily cause bloating, such as potatoes, sweet potatoes, soybeans, onions, etc. After the removal of the gastric tube, you can feed water several times in small amounts and gradually increase the amount. If the patient feels abdominal distension and pain, stop eating or drinking immediately to prevent complications such as intestinal obstruction or gastroparesis.
