Dyslipidemia generally refers to elevated cholesterol, LDL, very low density lipoprotein, triglycerides and decreased HDL. Dyslipidemia can lead to atherosclerosis and increase the morbidity and mortality of cardiovascular diseases. Therefore, the intervention of dyslipidemia has a great role in the prevention of diseases. The diagnosis of dyslipidemia relies mainly on laboratory tests of lipids. The key targets of lipid examination are: 1. Patients with cardiovascular disease, obesity, diabetes, smoking and alcohol consumption. 2. People who have cardiovascular disease in their family or have dyslipidemia. At present, it is generally advocated that people aged 20-39 should be checked for abnormal lipids every five years, and people aged 40 and above should have their lipids checked once a year. For patients with atherosclerosis and cardiovascular diseases, lipid tests are generally performed once every 3-6 months. The first detection of abnormal lipids should be reviewed in about 4 weeks, and if the review is abnormal, the diagnosis of abnormal lipids can be established. For people with dyslipidemia, active intervention is needed with the aim of reducing the incidence of cardiovascular disease and mortality. The most basic treatment for dyslipidemia is diet and exercise and quitting smoking and alcohol. In clinical practice, we often see a group of people who, despite taking oral lipid-adjusting drugs, do not pay attention to diet control, do not engage in physical activity, and continue to smoke and drink alcohol. This situation is not desirable. It is also easy to cause the occurrence of cardiovascular and cerebrovascular diseases. Dyslipidemia should limit cholesterol intake and control weight. If you have diabetes, hypothyroidism, etc., it is possible to cause dyslipidemia. It is necessary to actively treat the primary disease. In conclusion, the control of dyslipidemia is not something that can be improved in the short term. It requires long-term adherence to a good lifestyle, quitting smoking and drinking, physical activity, weight control, and proper consumption of fruits and nuts.
