Lipids are mainly serum total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol and other indicators, while blood lipids 6 point more mmol per liter is usually more serious. Lipids are mainly lipids contained in the blood, which can help to diagnose dyslipidemia, as well as assess the risk of coronary atherosclerotic heart disease and cerebral ischemic vascular disease; the normal levels of lipid-related indicators are mainly total cholesterol <6.20mmol/L, triglycerides <2.3mmol/L, HDL cholesterol 1.16~1.42mmol/L for men and 1.29~1.56mmol/L for women. 1.29~1.56mmol/L, LDL <4.14mmol/L. If the blood lipid is more than 6 mmol per liter, it means that the total cholesterol, triglyceride, LDL cholesterol of any one of the indicators, have exceeded the normal value, so it is more serious. Of course, if the LDL cholesterol is more than 6 millimoles per liter, then it is very serious, and it is recommended to consult a doctor as soon as possible. The cause of the disease may be due to genetic abnormalities of lipid metabolism, diabetes mellitus, hypothyroidism, renal insufficiency, systemic lupus erythematosus and other diseases, but we can not rule out high-fat diets, excessive alcohol consumption and other physiological factors. When the above symptoms appear, it is recommended to go to the hospital in time for consultation and guidance of standardized treatment.
