Pregnancy may aggravate gallbladder stones and may even induce acute cholecystitis. During pregnancy, as pregnant women eat more nutrients, it is easy to cause significant weight gain. At this time, the weight gain is not only caused by fetal development, many women will also have significant fat accumulation, and may even lead to the emergence of hypercholesterolemia. The formation of gallbladder stones is closely related to the imbalance in the ratio of cholesterol to lecithin and bile acids. Therefore, too much cholesterol can easily cause the concentration of cholesterol in bile to be oversaturated, thus precipitating cholesterol crystals, which will further cause gallbladder stones to increase in size and number. Therefore, women during pregnancy should still pay attention to high protein and high vitamin food intake. Although it is very important to increase nutrition, but should pay attention to the right amount, to avoid excessive weight gain, too fast, otherwise, not only will cause gallbladder stones, but also may aggravate the fatty infiltration of the liver.
