Patients should observe good eating habits, eat regularly and quantitatively, insist on eating less and more meals, 5-6 meals per day is appropriate; main food and side dishes should be soft and easy to digest, eat a little less at each meal to adapt to the characteristics of small stomach capacity, chew slowly to promote digestion, never overeat, and at the same time should pay attention to dietary hygiene. If you feel a choking sensation in swallowing within a short period of time after surgery, or a little bit of acid or bitter water after meals, it is within the normal range after surgery, and you can not mind too much or worry about it. Selective supplementation of nutrients 1, should be mainly starchy food recommended to eat potatoes, groundnuts, flour, cereal flour food; 2, should choose easy to digest and absorb fat, such as vegetable oil, cream, egg yolk, etc.. If steatorrhea occurs in a few patients after surgery (refers to diarrhea when pulling out a lot of fat particles), fat intake should be reduced; 3, should be supplemented with a high protein diet, choose easily digestible, essential amino acid variety of food, such as eggs, fish, shrimp, lean meat (note: beef and lamb must be fine rotten), soybean products, etc.. Increase the amount of vitamins and minerals by using animal liver, fresh vegetables, and fresh fruits (such as apples, bananas, oranges, kiwis, grapes, etc.) to increase the amount of various vitamins and minerals. It should be noted that after gastric surgery, patients are prone to malnutrition anemia, so appropriate use of lean meat, fish, shrimp, animal blood, animal liver, egg yolk, soy products, and protein- and iron-rich foods such as dates, green leafy vegetables, and sesame paste can be used to prevent anemia. More importantly, after total gastrectomy, patients are prone to malnutrition anemia, so vitamin B12, iron and calcium levels must be tested regularly, and supplementation of vitamin B12, iron and calcium must be considered appropriately. Chew slowly to promote digestion After surgery, the grinding function of the stomach is affected to some extent, so the chewing function of the teeth should play a more important role, and for the coarser and less digestible food, it is more important to chew slowly; if you want to eat soups or drinks, you should pay attention to the separation of dry and thin, and try to eat soups 30 minutes before or after meals to prevent the food from being discharged too quickly to affect digestion and absorption. Food taboos As the physiological function of the patient’s stomach is weakened after surgery, special attention should be paid to dietary taboos. 1, usually should avoid eating cold, coarse and hard food; 2, avoid eating spicy and stimulating condiments, such as pepper, mustard, etc.; 3, strictly forbidden to drink strong wine, strong tea and other stimulating food; 4, avoid excessive oil and too rough food, such as fried chicken, fries and other fried food. 5, the texture of the food should be soft and easy to digest, should not eat coarse grains, dried beans, hard fruits, vegetables with high crude fiber content (celery, leeks, beans, bamboo shoots, celery, etc.), spicy and stimulating and gas-producing food (such as radish, garlic, etc.). These foods are not completely off limits, but it is just a matter of volume and personal tolerance for these foods that needs to be considered. The above points are the basic principles of postoperative dietary regimen for gastric surgery patients, and other aspects do not need to be too taboo. After patients are discharged from the hospital, they can resume eating with their family members. The amount of food they eat is generally based on their own feelings, and if they feel full, bloated, etc., they should adjust their food. 6. Take salicylic acid drugs, such as aspirin, as little as possible. Three months after discharge from hospital, patients can resume eating together with their family members. The amount of food is generally based on their own feeling, and they should develop good eating habits, eat regularly and quantitatively, insist on eating less and more meals, and choose fresh, soft and easily digestible food for staple food and side dishes. The above points are the basic principles of postoperative diet for gastric cancer surgery patients.
