Gallbladder stones are a type of gallstones and can be formed by factors that affect the ratio of cholesterol to bile acid concentration and cause bile stagnation. It can be simply understood that when bile is stagnant or concentrated, it tends to form precipitates, which over time result in insoluble stones. On the other hand, the occurrence of gallbladder stones is also related to the body type, and gallbladder stones tend to occur in obese women in their 40s. It is worth mentioning that gallbladder stones are also closely related to lifestyle habits. The gallbladder bile in the dinner from the new beginning of storage, if the next day do not eat breakfast, after about 12 hours of storage, concentration, cholesterol in the bile is more saturated, easy to form cholesterol crystals, day after day gradually formed stones. In contrast, if you eat breakfast normally, the cholesterol will be excreted with the bile due to the contraction of the gallbladder, and the food will stimulate the secretion of bile instead of stagnating in the gallbladder, so it is not easy to cause the high saturation of cholesterol in the bile in the gallbladder, and it is not easy to form stones. So how to carry out prevention? 1, regular diet; regular eating allows bile to be discharged regularly and not to be overly concentrated, thus preventing the formation of stones. 2, weight control, reasonable diet; obesity makes us more prone to gallbladder stones, so avoid high-fat, high-calorie eating habits and maintain a good weight. Eating more fiber-rich foods can improve cholesterol metabolism and help prevent stone formation. 3, vegetarians should be properly supplemented with lecithin; normal human cholesterol and bile salts, lecithin in a certain ratio mixed into microcolloid particles suspended in the bile, when this ratio is destroyed, easy to form gallstones. Some vegetarians do not consume enough lecithin, and too much fiber in the vegetarian diet prevents the reabsorption of bile acids, so that the concentration of bile salts in the bile decreases, should be properly supplemented with lecithin.
