To determine whether bile acids are elevated in pregnant women, it is necessary to ask pregnant women to undergo serologic tests of liver function in a fasting state to clarify whether bile acids are within the normal range. Bile acid is one of the products of cholesterol decomposition and metabolism, and when the patient has a hyperlipidemic and hypermetabolic condition, the level of bile acid will also increase. During pregnancy, the physiological function of the liver may change, and in order to provide adequate nutrition for the fetus, pregnant women also eat more compared to before pregnancy. And due to the further growth of the fetus, it will cause some pressure on the liver, leading to changes in the function of the liver of pregnant women. If pregnant women have high bile acids, it is recommended that they follow the dietary principles of vegetables and fruits, supplemented by animal proteins, and take appropriate choleretic drugs while taking into account the nutrition of the fetus. Symptoms of high bile acids in pregnant women can usually be greatly improved after the end of pregnancy.
