After subtotal or total gastrectomy, patients with gastric cancer should not only pay attention to nutritional supplement, but also adjust their food intake and types according to their own dietary tolerance and stomach capacity. In short, the diet should be nutritious and easy to digest. In general, patients should follow the following principles: eat less and eat more, because after radical gastrectomy or total gastrectomy, jejunum interposition replaces the stomach, only a small part of the stomach remains, and the food intake is obviously reduced. Only by increasing the number of meals can we make up for the lack of food and meet the body's demand for nutrition. Therefore, patients should develop good eating habits, eat regularly and quantitatively, and insist on eating less and more meals, preferably 5-6 meals a day. Staple food and side dishes should be soft and easy to digest. Never overeat. Eat more fish in the early postoperative period according to the order of water, clear water, liquid food, semi-liquid food, soft food and general food. Eat rice soup, egg soup, vegetable soup and lotus root powder, and avoid foods that induce flatulence. Semi-liquid diet should choose high protein, high calorie, high vitamin, low fat, fresh and digestible food. The best source of animal protein is fish, because fish is not only rich in protein, but also has similar amino acid composition and proportion to human body. The utilization rate of fish protein can reach 96%, and fish fat contains high unsaturated fatty acids, which are easily digested and absorbed by human body. Therefore, we encourage people to eat more fish such as yellow croaker and crucian carp. After entering the ordinary diet, we should eat more high-fiber foods such as vegetables and fruits to keep the stool unobstructed and promote the excretion of toxins. Eating less sweets (1) and eating too much sugar can easily cause hyperosmotic dumping syndrome (discomfort after gastrectomy). Therefore, sugar should be properly controlled, and the energy supply of sugar should account for 50% ~ 60% of the total heat. To avoid eating too sweet food, starchy food should be the main food. (2) The energy supply of fat should not exceed 35% of the total energy. Avoid eating animal meat fat and choose fats that are easy to digest and absorb, such as vegetable oil, cream, egg yolk, etc. If a few patients have fatty dysentery after operation (refers to pulling out a lot of fat particles during diarrhea), they should reduce their fat intake. (3) A high-protein diet should be supplemented, and foods that are digestible and complete in essential amino acids should be selected, such as fish, eggs, shrimp, lean meat and bean products. The energy supply in protein accounts for 15% ~ 20% of the total energy. For example, a person weighing 70kg can consume 70 ~140g of protein every day. Food taboo 1, avoid eating cold, overheated and hard food; 2, avoid eating spicy and irritating condiments, such as pepper, mustard, etc.; 3. It is forbidden to drink strong liquor, strong tea and other stimulating foods; 4. Avoid greasy and coarse grains, such as fried chicken, fried dough sticks and other fried foods; 5. It is not advisable to eat coarse grains, dried beans, hard fruits and vegetables with high crude fiber content (bamboo shoots, celery, etc.). ), spicy and gas-producing food (such as radish, garlic sprout, sweet potato, etc.). ) these foods are not completely inedible, just need to consider the quantity of these foods and the individual's affordability. The above points are the basic principles of postoperative dietary adjustment for patients with gastric cancer, and other aspects need not be too taboo. After the patient is discharged from the hospital, dinner can be resumed with his family. Generally, the amount he eats is mainly based on his own feelings. If he has symptoms such as fullness, bloating, diarrhea, dizziness and palpitation, he should stop eating to prevent complications. Prevent anemia, animal liver, fresh vegetables, etc. Appropriate selection should be made to improve the acquisition of various vitamins and minerals. It should be noted that after gastric cancer surgery, patients are prone to iron deficiency anemia, and foods rich in protein and iron, such as lean meat, fish, shrimp, animal blood, animal liver, egg yolk, bean products, jujube, green leafy vegetables and sesame sauce, can be properly eaten to prevent anemia. After chewing slowly, the grinding function of the stomach is lost, and the chewing function of the teeth should play a more important role. For rough and indigestible food, you should chew slowly. If you want to drink soup or water, you should pay attention to the separation of dry and wet, and try to drink soup 3 0 minutes before or after meals to prevent food from being discharged too quickly and affecting digestion and absorption. Rest on your side after meals to prolong the emptying time of food and make it fully digested and absorbed. The patient's diet will be restricted after the operation. The most important thing is not to panic too much. On the basis of understanding your physical changes, keep cheerful and enjoy the fun brought by food.
