Gallbladder stones are difficult to prevent, but the occurrence of stones can be reduced according to the following principles: 1. Regular eating (three meals a day) is the best way to prevent stones because the gallbladder is full of bile when fasting, and the gallbladder mucosa absorbs water to thicken the bile, at which time the cholesterol/lecithin vesicles tend to form and the viscosity of the bile increases, finally forming bile sludge. In case of overeating, when the food enters the duodenum, the gallbladder contraction hormone is secreted in response, which causes the gallbladder to contract. Therefore, it can prevent the formation of stones. 2, choose a reasonable diet structure, avoid high protein, high fat, high calorie diet habits. Eat a proper fiber-rich diet to improve the excretion of cholesterol and prevent the formation of stones. 3. Maintain the contractile function of the gallbladder to prevent long-term bile depression. For patients who use intravenous nutrition for long-term fasting, drugs such as cholecystokinin can be used. 4.Actively treat some primary diseases that can cause gallbladder stones, such as hemolytic anemia and hepatic sclerosis, because these diseases can easily induce gallbladder bile pigment type stones. In addition, from the medical point of view, the following principles can be followed: 1. primary prevention: prevention of cholesterol supersaturated bile formation, avoiding obesity, increasing calcium and fiber intake, reducing saturated fatty acid intake, regular meals, increasing exercise, and planned medication for high-risk groups; 2. secondary prevention: establishing a sound treatment program for asymptomatic gallstone disease to prevent its transformation into symptomatic gallstone disease, and sound various Tertiary prevention: primary prevention program to correct the pathological basis of gallstone formation in the body, avoid recurrence of stones, regular review with diet mediation, avoid obesity, and strengthen physical exercise; 4.
