1, control calories to reduce 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. 2, reduce fat and cholesterol. Pay attention to a 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 Foods with high fat content such as peanuts, melon seeds, walnuts, almonds, pistachios, etc. Strictly limit animal offal, egg yolk, squid, sardines, animal brains, 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. 3, 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. 4, vegetables and fruits to protect 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. It can reduce the formation of cholesterol, reduce the absorption of fat and sugar, thus playing a role in reducing blood lipids and blood sugar. 5, smoking, alcohol and spicy need to quit. Patients who have had their gallbladder 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. 6, coarse grains are beneficial to choose more, eat more food containing high dietary fiber, including corn, millet, sweet potatoes, oats and other coarse grains to promote bile excretion. 7, pay attention to cooking there are methods. Cooking should strive to light, preferably using stewing, steaming, simmering soup and other methods. Avoid deep-frying, barbecue, smoking, half-cooked boiling methods, and use as little condiments 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 reduced by half compared with normal people. 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 you are uncomfortable after eating, you can reduce or not eat as appropriate, and then gradually release the intake of fatty foods after a period of adaptation. The health and longevity of each person depends 60% on oneself, 15% on genetic factors, 10% on social factors, 8% on medical conditions, 7% on climatic factors, while 48.9% of the underlying causes of human death are poor lifestyle and behavior, 23.2% are biological genetic factors, 17.6% are environmental factors, and 10.3% are medical service factors. 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). However, another important function of the gallbladder is to regulate the entry of bile into 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 combination 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, and in general, we should grasp the above seven links. Develop good living habits and scientific diet in daily life.
