After cholecystectomy, we should pay more attention to the reasonable collocation of diet structure, correct bad eating habits, and continue to maintain the principle of low calorie, low fat, high protein and high vitamins. To sum up, we should do the following seven links. 1. Control calories and lose weight. Every meal must be seven or eight minutes full (especially dinner) to keep your weight within the ideal range. Overweight and obese patients should lose weight. 2. Reduce fat and cholesterol, pay attention to the reasonable collocation of meat and vegetables, and try to reduce the fat and cholesterol content in food. After cholecystectomy, due to the lack of enough concentrated bile, excessive intake of fat and cholesterol will lead to digestive dysfunction, fatty diarrhea and malnutrition. Usually eat more vegetable oil, avoid animal oil, and try to eat less thick soup, chicken soup and fish soup. Reduce the intake of nuts with high fat content, such as peanuts, melon seeds, walnuts, almonds and pistachios. Strictly restrict high cholesterol foods such as animal viscera, egg yolk, squid, sardines, animal brains, fish eggs and crab roe. Eat up to 4 eggs a week. Avoid overeating or excessive hunger, and eat as little as possible. 3. High-quality protein should be supplemented with sufficient protein, which is beneficial to repair the liver cell damage caused by cholecystitis and cholelithiasis, so you can choose a low-fat high-quality protein diet, and fish, shrimp, poultry, tofu and bean products are less oily. Vegetables and fruits are healthy. Vegetables and fruits are rich in vitamins, minerals and dietary fiber, which can reduce the formation of cholesterol and the absorption of fat and sugar, thus improving the metabolic disorder of patients and reducing blood lipid and blood sugar. The daily intake of vegetables should be above 500g, and there are at least two kinds of fruits. 5. coarse grains are beneficial. Choose foods with high fiber content, including corn, millet, sweet potato, oats, buckwheat and other coarse grains to promote bile excretion. 6. Patients who must quit smoking and drinking and have their gallbladder removed must quit smoking and drinking, because smoking and drinking will increase the burden on the liver, and at the same time eat less irritating foods such as onions, garlic, ginger, peppers, peppers and curry. 7. Pay attention to cooking. If you have a way to cook, try to make it clear. It is best to stew, boil and simmer soup, avoid frying, roasting, smoking and boiling half-cooked, and use as little seasoning as possible. Only in this way can we adapt to the changes of biliary tract function after operation and reduce the burden of digestive system. After dietary guidance, there will be some changes in the human body, and these changes in the body are to meet the needs of digestion. This process takes half a year, during which the function of digesting and absorbing fat will be temporarily affected. Pay attention to diet, eat less and eat more, and the diet should be nutritious, less greasy, moderate in taste and easy to digest. Patients should be encouraged to eat. Only by supplementing nutrition can their condition be better and firmer. We should control foods with high cholesterol, reduce the disorder of cholesterol metabolism, and limit foods with high cholesterol such as animal viscera, egg yolk, salted duck eggs, preserved eggs, fish eggs and crab roe. You should limit the intake of seaweed and seafood, drink some yogurt and exercise properly. Just finished the operation, I suggest to have more rest. For the specific causes of pain, you can consult a doctor. You must avoid drinking and smoking, so as not to be harmful to your condition. Generally speaking, within six months after cholecystectomy, the diet should be light, low in oil, high in protein (without egg yolk) and high in calories. You can eat more meals in small quantities, especially if you don't eat too much animal fat food (so-called low-fat diet) at one time, such as fat meat and pig's trotters. After a period of operation (about half a year), when the body recovers well, a small amount of fatty food can be supplemented one after another, so as not to cause indigestion such as abdominal discomfort and diarrhea. 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
