In recent years, laparoscopic cholecystectomy has been widely used. This surgical method has few complications and exact results, and is currently the most suitable surgical method for treating benign gallbladder diseases (cholecystitis, gallbladder stones), and after surgical removal of the gallbladder, patients can obtain their own regulatory compensation after a period of adjustment and recovery, that is, through compensatory expansion of the bile ducts, to maintain the basic Physiological functions. However, another important function of the gallbladder is the regulation of bile entering the intestinal tract. Once the gallbladder is removed, its function of regulating bile excretion no longer exists, and the physiological integrity and functional coordination of the biliary tract are damaged to a certain extent. Disorders, such as steatorrhea, vitamin malabsorption and other syndromes, etc. Also, although gallstone patients have their stones removed through surgery, they do not change the disorder of lipid metabolism that produces stones, and this metabolic disorder also easily leads to other diseases, such as hypertension, arteriosclerosis, heart disease, etc. Therefore, after gallbladder removal, it is more important to pay attention to the reasonable matching of dietary structure, correct the bad dietary habits, and continue to maintain the dietary principles of low calorie, low fat, high protein and high vitamin, in general, the following seven links should be grasped. One: control calories to reduce body weight, control the total amount of food eaten, each meal should be seven or eight minutes full (especially dinner). Keep the weight within the ideal range, overweight and obese people should lose weight. Second: reduce fat and cholesterol. Pay attention to the reasonable combination of meat and vegetables, try to reduce the fat and cholesterol content of food, after gallbladder removal, due to the lack of sufficient concentrated bile, if excessive intake of fat and cholesterol, will cause digestive disorders, heavy fat diarrhea, resulting in malnutrition, usually advocate the use of vegetable oil, avoid the intake of animal oil, try to eat less thick meat soup, thick chicken soup, thick fish soup and other foods, reduce the intake of fatty nuts Reduce the intake of fatty nuts such as peanuts, melon seeds, walnuts, almonds, pistachios, etc. Strictly limit animal offal, egg yolk, squid, sardines, animal brain, fish eggs, crab yolk and other foods containing high cholesterol, eat up to four eggs per week, avoid overeating or excessive hunger, try to do a small number of meals. Three: high-quality protein to supplement. Adequate protein supplementation is conducive to repairing liver cell damage caused by cholecystitis and cholelithiasis. You can choose low-fat high-quality protein based on fish, shrimp, poultry, tofu and less oily soy-based post-cholecystectomy diet maintenance way products, etc. The way to maintain the diet after cholecystectomy four: vegetables and fruits to ensure health, daily vegetable intake should be greater than 500 grams. There are at least 2 kinds of fruits, vegetables and fruits are rich in vitamins and minerals, which help improve the patient’s metabolic disorders and facilitate recovery, vegetables and fruits are also rich in dietary fiber. Can reduce the formation of cholesterol, reduce the absorption of fat and sugar, thus playing a role in reducing blood lipids and blood sugar. Five: coarse grains are beneficial to choose more, more food containing high dietary fiber, including corn, millet, sweet potatoes, oats and other coarse grains to promote bile excretion. Six: smoking, alcohol and spices need to be quit. Patients who have had their gallbladders removed. Be sure to quit smoking and alcohol, because smoking and alcohol abuse will increase the burden on the liver. Eat less spicy and other stimulating food, such as onions, garlic, ginger, chili and pepper, etc. Seven: pay attention to cooking there are methods. Cooking should strive to light, preferably using stewing, steaming, simmering soup and other methods. Avoid deep-frying, barbecuing, smoking, half-cooked boiling methods, and use as little seasoning as possible, so as to suit the changes in biliary function after surgery and reduce the burden on the digestive system. The normal gallbladder has the functions of storage, concentration, bile discharge and secretion. After removal of the gallbladder, the organism loses the above-mentioned functions of the gallbladder. The problem of fat digestion is that there is no concentrated gallbladder bile entering the small intestine, the concentration of bile acids in the intestine does not reach the critical microcolloid concentration, and the content of bile salts is also reduced by half compared with normal people, so if the fat content in the food consumed is high, it will cause poor digestion of fat and affect the absorption of fat-soluble vitamins A, D, E and K. However, after a period of time, the body will gradually reduce the burden on the digestive system. However, after a period of time, the body will gradually adapt and compensate, and this process takes 2 – 3 months. Therefore, during this period of adaptation, the intake of fat should be limited, especially not to eat food containing too much animal fat at one time. Generally, small and frequent meals are used, and one meal should not be too full. Food content can be low-fat semi-fluid or low-fat soft meals. Such as a variety of porridge, noodles, pasta, bread, cookies, tofu, egg whites, fat-free milk and low-fat lean meat, less fiber vegetables, fruits, etc.. Cooking with stewing, steaming, boiling and blanching to make the food soft and less oily is appropriate. Fat control transitions from a strict 20 grams per day to 40 grams per day, depending on tolerance to food. If uncomfortable after eating can be reduced or not eaten as appropriate, after a period of adaptation and then gradually release the intake of fatty foods.
