1, gastrointestinal tract is stimulated, peristalsis is reduced, liver function is inhibited, and bile secretion is reduced after operation, which will affect the function of the whole digestive system. Therefore, strict fasting and various nutrition supplements should be given by intravenous drip for 1 ~ 2 days after operation. On the third day, depending on the situation, liquid food, such as rice soup, soybean milk, lotus root starch, juice and so on. Give them separately, and then gradually change to skim milk with sweet bread, rice porridge, bean curd soup, jujube paste and pasta. 2. Within 1 month after operation, the intake of fatty foods, fast-high-fat and fried foods should be reduced. Some people think that it is wrong to change the past low-fat diet after removing the "key points". After cholecystectomy, the function of regulating bile discharge into the intestine will be lost, and the digestion ability of fat will be weakened accordingly. In particular, digesting a lot of fatty foods in a short time will cause abdominal distension, diarrhea and indigestion, which is beyond our power. Reducing fat intake mainly refers to eating as little fat, animal offal, egg yolk and fried food as possible, which is not suitable for eating all kinds of "fast food" with high fat and high calorie. Use as little animal oil as possible when cooking, and increase vegetable oil appropriately. The dishes should be mainly steamed, stewed and cold, and eat less stir-fry, especially spicy food and alcohol, so as to reduce the adverse stimulation to the biliary tract. 3. Gradually strengthen nutrition. After cholecystectomy 1 month, the diet should also be light, and strengthening the necessary nutritional supplements will help patients recover as soon as possible. After several weeks of adaptation and compensation, the common bile duct connecting the liver and small intestine gradually expanded, replacing the gallbladder's function of storing bile. If there is no abnormality in digestive function, you can eat a normal diet. Protein's intake can be increased appropriately, and you can eat some high-quality food from protein. Eat lean meat, aquatic products and beans every day, and drink a glass of milk is better. If you are not used to eating milk or fish, you can eat more soy products and mushrooms to make up for the lack of animal protein. In principle, it is not advisable to consume too much fat and cholesterol after cholecystectomy, but it is not necessary to restrict fat excessively, because a certain amount of fat in the intestine is necessary to stimulate bile secretion, expand the volume of the common bile duct and keep the biliary tract unobstructed. In addition, eating more foods rich in fiber and vitamins is also very beneficial to the postoperative recovery of patients. 4. appropriately increase the number of meals. It should be noted that it is not advisable to eat more meals per meal, especially within 3 ~ 6 months after operation, and it is advisable to eat four meals a day. Eating less and eating more can reduce the burden on the digestive system and help to restore health after operation. It is best to be jealous every day, because vinegar can enhance the digestive ability of the stomach and adjust the pH in the intestine, thus helping bile to play its role and promoting the digestion of fatty foods. Drinking tea regularly and eating more fruits and vegetables are also helpful to the digestion and absorption of food. Breakfast: rice porridge (50g of rice), flower rolls (50g of flour), bean curd with soy sauce10g, and cucumber with soy sauce10g. Meal: tomato juice (tomato 100g, sugar 5g), cake 20g.
