Blood lipids often include total cholesterol, triglycerides, apolipoproteins, high-density lipoproteins and low-density lipoproteins. High cholesterol and triglycerides are manifestations of hyperlipidemia. Therefore, once an increase in blood lipids is detected, it requires constant attention and active treatment. Once cholesterol exceeds 11 mmol/l, it can seriously affect the development of the fetus and even lead to fetal malformation. In this case, pregnant women need to be admitted to the hospital, given lipid-lowering medication as prescribed by the doctor, and reviewed regularly. If the high blood lipid level is not serious, it can be adjusted by diet, eating more foods rich in vitamins, fiber and unsaturated fatty acids, more fruits and vegetables, such as apples, bananas, corn, carrots, beans and soy products; if you are not allergic to seafood, you can eat salmon, sardines, oysters and other foods that can help lower lipid level, and also eat seaweed, nori, shiitake mushrooms, fungus and other foods that can help prevent arteriosclerosis. Foods with high cholesterol content, such as egg yolk, fatty meat, animal offal, etc., should be avoided. In addition to good dietary habits, we should also pay attention to appropriate activities and exercise to ensure the nutrition of pregnant women and fetuses while actively controlling weight, as well as developing good habits of going to bed early and waking up early to maintain a happy mood.
