The dietary considerations after gastric cancer surgery can be divided into the following points: 1. Fasting should be done after surgery; when the gastric tube is removed and the intestinal tract begins to exhaust, a small amount of water can be drunk, and the patient’s changes can be observed. The diet should be as light as possible, easy to digest and absorb, and avoid irritating food. 2. After resuming normal diet after gastric cancer surgery, you should continue to pay attention to control diet, avoid spicy and stimulating food, fried food, alcohol, strong tea and coffee drinks, and pay attention to not overeating and eating three meals regularly. In addition, after gastric cancer surgery, you should regularly review gastroscopy, blood routine, tumor markers, liver function, kidney function and other indicators, and seek medical consultation whenever you are unwell to avoid delaying the disease.
