Gallstones are caused by the crystallization of cholesterol in an imbalanced ratio of bile acids to cholesterol in the bile. Although the cause of gallstone disease is not known with certainty, it is known to be related to a number of factors. 1.Lifestyle Gallstones are a typical lifestyle disease. (1) Metabolic disorders The ratio of cholesterol, bile acids and phospholipids in bile is very important to maintain the dissolved state of cholesterol, if the body’s metabolism is disturbed, resulting in an imbalance in the ratio of the three, cholesterol will be deposited and stones will be formed. Studies have shown that people whose body weight exceeds the normal standard by more than 15% have a 5 times higher incidence of gallstones than normal people, and one of the reasons is that obese people have metabolic disorders. (2) high-fat diet Long-term addiction to fatty foods and other high-fat diet, the body will increase the blood lipids, resulting in high saturation of cholesterol in the bile, easy to form stones. (3) do not eat breakfast Some friends reflect on the reason why they suffer from gallstones, may be during school, do not eat breakfast related. Not eating breakfast for a long time will increase the concentration of bile, which is conducive to bacterial reproduction, and promote the formation of gallstones. (4) Lack of exercise and physical labor, over time, resulting in reduced gallbladder function, decreased contraction of the gallbladder muscle, bile evacuation will be delayed, easy to cause bile stagnation, cholesterol crystals precipitation; also will prevent the reabsorption of bile acids, resulting in the deposition of cholesterol into stones. 2, the mood is not smooth gallstones is a typical psychosomatic disease.
