The vast majority of people with high LDL can lower it through diet, exercise, and taking atorvastatin and other medications as prescribed by the doctor. However, a very small number of people with poor results of the above mentioned treatments may need to have their blood filtered to lower their blood lipids. High LDL also belongs to hyperlipidemia, and this kind of people have higher risk of cardiovascular and cerebrovascular diseases, so they need to lower the blood lipid treatment, which can be done by the following ways to lower the blood lipid: 1. Dietary modification, including a light diet, less fried food, animal offal, cream products, fatty meat, barbecue, hot pot, etc.; more green leafy vegetables, such as celery, spinach, oleander, cucumber, bitter melon, etc.; staple food should be a combination of coarse and fine, and coarse grains can be chosen from buckwheat, quinoa, brown rice, etc.. Each meal can be 70% full, do not overeat. 2. appropriate exercise mainly choose aerobic exercise, such as running, swimming, playing ball, dancing, cycling, etc., each effective exercise time of not less than 30 minutes, at least 3-4 times a week. Through exercise to reduce weight, reduce body fat rate. 3. If the effect of diet and exercise is poor, LDL can be lowered through medication, you can choose to inhibit cholesterol absorption of statin drugs, such as atorvastatin calcium, Rosuvastatin, pitavastatin; choose to inhibit cholesterol absorption of ezetimibe; inhibition of the degradation of low-density lipoprotein receptor PCSK9 inhibitors. If the effect of one drug alone is poor, it can be used in combination. 4. If the effect of lowering blood lipids through the above methods is poor, plasma exchange or blood filtration may be necessary, but only for rare cases of serious conditions. It is recommended that patients should consult a doctor in time and standardize the treatment under the doctor’s guidance, and should not use drugs blindly on their own.
