The post-operative diet of gastric cancer patients varies slightly according to the specific surgery method, as follows: 1. After gastric cancer surgery, due to the reduction of stomach volume and digestive tract reconstruction, it is recommended to eat soft and easily digestible food, and at the same time, it is recommended to eat high-protein, low-sugar and low-fat food; 2. Since gastric cancer is formed by the stimulation of many factors, post-operative patients should avoid bad stimulating food as much as possible, such as spicy, overheated and indigestible food; 3. 3. Since the volume of stomach shrinks after gastric cancer surgery, it is recommended that patients should eat less and more meals after surgery, with regular and quantitative meals each time; at the same time, they should develop regular eating habits and form the habit of eating less and more meals to promote postoperative recovery, increase nutrition and physical fitness, so as to provide a good foundation for smoothly entering the next comprehensive treatment.
