LDL is actually a kind of cholesterol, which is one of the usual blood lipid levels and can cause atherosclerosis and plaque formation, inducing coronary heart disease, stroke and carotid atherosclerosis, hence the alias “bad cholesterol”. If you have high LDL, you can lower it by adjusting your daily diet. If the high level is more serious, you can also take medication to adjust: 1. Adjusting lifestyle habits: 1. Therefore, the daily diet should be limited to foods rich in saturated fatty acids, such as fried foods and soft snacks, and it is recommended to keep the daily diet light and eat more fruits, vegetables, coarse grains and other foods to increase the intake of vitamins and fibers in moderation. Exercise such as walking, playing Tai Chi, etc., gradually transition to brisk walking, jogging and other medium-intensity exercise; 3, quit smoking and alcohol: tobacco nicotine, carbon monoxide, etc., can trigger and aggravate the occurrence and development of atherosclerosis; and the high calorie content of wine, drink more to aggravate obesity, is not conducive to the reduction of LDL. Second, take drugs: through the above methods, LDL is still not reduced to the ideal level, or has been complicated by coronary heart disease, stroke, peripheral atherosclerotic changes to consider oral drugs. Drugs to lower LDL include statins, drugs that inhibit cholesterol synthesis such as ezetimibe, and PCSK9 inhibitors. Of these, statins are the cornerstone, especially in patients who have developed atherosclerosis. They include atorvastatin, resulvastatin, etc. However, statins have effects on liver and kidney function, muscle tissue, and blood sugar, so it is recommended to review them regularly after taking them.
