High blood lipids during pregnancy may be caused by a high-fat diet of the pregnant woman along with a lack of exercise, secondary to other diseases, genetic factors and other reasons. Blood lipids can be lowered through dietary adjustments, moderate exercise and treatment of primary diseases. 1. High-fat diet and lack of exercise: If pregnant women consume too much fat during pregnancy, resulting in obesity, and at the same time lack of exercise, it will affect the metabolism of blood lipids, resulting in the occurrence of hyperlipidemia. At this time, pregnant women should adjust their diet, try not to eat greasy, fried food, eat fresh fruits and vegetables and other foods, but also through appropriate exercise to reduce blood lipids. 2. Secondary to other diseases: If pregnant women suffer from hyperlipidemia, hypothyroidism, Cushing’s syndrome, polycystic ovary syndrome, etc., it may also cause secondary elevation of blood lipids. At this time, the treatment of the primary disease to reduce blood lipids, when the primary disease is under control, blood lipids can often be reduced. 3. Genetic factors: If pregnant women have familial hyperlipidemia, pregnant women should pay more attention to diet control, but generally should not use lipid-lowering drugs during pregnancy. If a pregnant woman’s blood lipids cannot be lowered by the above methods, it is recommended that she consult a doctor in a timely manner, and under the guidance of the doctor, complete the relevant examinations to clarify the cause of the disease and treat the symptoms.
