If total cholesterol and triglycerides are elevated during pregnancy, this phenomenon is most likely due to the fact that the patient always has a high-fat diet during pregnancy, exercises less and eats more, which will indirectly trigger hyperlipidemia. Patients must pay attention to control the rate of weight gain, try to achieve a low-salt, low-fat diet, and eat more green leafy vegetables. In addition, patients are advised to check kidney function and thyroid function if necessary, as some patients may also have hypothyroidism or nephrotic syndrome, which can also lead to elevated total cholesterol and triglycerides.
