High triglycerides generally do not cause fetal arrest, but may cause atherosclerosis and other cardiovascular diseases. High triglycerides in pregnant women are usually related to over-nutrition and do not have a direct effect on the fetus or the pregnant woman. Eating more high-calorie, high-fat and high-sugar foods after pregnancy, along with less activity, may cause triglyceride overload. It usually does not lead to fetal arrest because triglycerides have a high molecular weight and cannot pass through the placenta and will not have a direct effect on the fetus. However, high triglycerides may cause cardiovascular and cerebrovascular diseases, and also closely related to pancreatitis, and attention should be paid to the prevention of gestational diabetes or hypertension, pregnant women with excessive triglycerides should be controlled through diet.
