The prevalence of hyperlipidemia generally tends to increase with age, with peak incidence in the 50s and 70s, so people of advanced age should be alert to elevated blood lipids. The increase of blood lipids is obviously affected by diet and lifestyle. Controlling diet and improving lifestyle are the basic measures to alleviate high blood lipids. Regardless of whether drug treatment is chosen, lifestyle interventions must be adhered to: 1. Diet control: improve the diet structure, low-salt diet, restrict alcohol consumption and prohibit strong alcohol. And according to the degree of the patient’s lipid increase, develop recipes, eat less fatty meat, animal blood and offal products to limit the intake of animal cholesterol. It can be supplemented with plant sterols, such as celery, leek, hawthorn, soybean, mushroom, fungus, etc., and increase the intake of certain amount of soluble dietary fiber, such as konjac; 2. Increase exercise: at least 30 minutes of moderate intensity metabolic exercise every day, such as brisk walking, jogging, rope skipping, swimming, etc. Maintain an appropriate body mass index, BMI around 20, which refers to the weight in kilograms divided by the height in meters squared derived from number. Patients with a large weight base should gradually increase the amount of exercise to ensure the safety of exercise; 3. Quit smoking: nicotine, tar and other harmful substances in smoke can cause disorders of lipid metabolism and cause hyperlipidemia; 4. Regular review: Patients with high blood lipid levels must have regular ultrasound examinations to understand the vascular condition. Because patients with high lipid level are especially prone to atherosclerosis, if the plaques in the blood vessels are large and block the blood vessels, it may lead to blood vessel embolism, which may lead to cerebral infarction, myocardial infarction, ischemic necrosis of lower limbs, etc.; 5. The overall prevalence of dyslipidemia in adults in China is currently high. Currently, the overall prevalence of dyslipidemia among Chinese adults is as high as 40.4%, and dyslipidemia can lead to atherosclerotic cardiovascular diseases such as coronary heart disease, and increase the risk of tumors. The prevention and treatment of dyslipidemia is important to reduce the prevalence of cardiovascular diseases and improve the quality of life.
