With the improvement of living standards, people are more and more concerned about their health status. When they see normal blood lipid test results, they may take a long breath and finally feel relieved. In fact, everyone’s blood lipid standards are not the same. Even if the test results are within the reference value range, it does not mean that it is healthy, and it may have exceeded the standard.
To determine whether blood lipids are normal, we mainly focus on 4 indicators: total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), and low density lipoprotein cholesterol (LDL-C). Its reference range: TC is 2.8 to 5.17 mmol/L: TG is 0.56 to 1.7 mmol/L; HDL-C is 0.90 to 1.60 mmol/L; LDL-C is 0 to 3.1 mmol/L. Among them, high-density lipoprotein cholesterol is recognized as “good cholesterol” and has an anti-arteriosclerosis effect: low-density lipoprotein cholesterol is “bad cholesterol” and is the primary factor that causes arteriosclerosis. Atherosclerotic plaques are formed, blood vessels are narrowed, and blood flow is reduced, leading to the occurrence of diseases such as coronary heart disease and ischemic stroke.
Generally, the reference range marked on the test form is only applicable to healthy people. For people with risk factors such as coronary heart disease, diabetes, stroke, hypertension, smoking, and obesity, the risk of myocardial infarction and stroke in the future is higher than that of normal people. High, the standard value of its blood lipids, especially the level of low density lipoprotein cholesterol should be kept low.
According to the risk factors for dyslipidemia, male age 45 years old, female age ≥55 years old, obesity, smoking, family history of premature coronary heart disease, HDL-C<1.04 mmol/L, etc., the corresponding blood lipid index can be divided into 4 level:
Low-risk group: refers to people who only have one or two of the above-mentioned risk factors, requiring LDL-C<4.14 mmol/l, TC<6.22 mmol/l.
Medium-risk group: People with hypertension and accompanied by one or two of the above risk factors, the standard value should be LDL-C<3.37 mmol/L, TC<5.18 mmol/L.
High-risk groups: People with any of coronary heart disease, stroke, diabetes, and chronic kidney disease are high-risk groups. In addition, if you have high blood pressure, there are three of the above-mentioned risk factors at the same time, and they are also at high risk. The compliance value should be controlled within the range of LDL-C<2.59 mmol/l, TC<4.14 mmol/l.
Very high-risk population: people with coronary heart disease and diabetes, or who have had an acute coronary syndrome attack, try to control it to LDL-C<2.07 mmol/L, TC<3.11 mmol/L, and be sure to Take lipid-lowering drugs under the guidance of a doctor.
Therefore, for different risk groups, the blood lipid control level has different target values. You can not simply look at the arrow on the test sheet. You can sit according to the above indicators and see if your blood lipid level meets the standard.
Of course, pay attention to diet before the medical examination, which can make your examination results more accurate. 3 days before the test, avoid high-fat diet or deliberately change the way of life, so as not to reflect the actual situation of blood lipid test results, should maintain the same lifestyle as in the past. There should also be an empty stomach for 8 hours to 12 hours before blood drawing. Eating and excessive fasting can cause elevated blood lipid levels.
How to manage your blood lipids? First of all, we must control the diet and reduce the intake of lipids. We can replace some meat and milk with beans, eat lean meat and fish, eat oats and fruits, eat less staple food and sweet foods, and try to quit smoking and alcohol. Second, we must adhere to aerobic exercise, increase "good cholesterol", jogging, Tai Chi, swimming, mountain climbing, cycling and other aerobic exercises 3 to 4 times a week, adhere to more than 3 months can effectively improve blood lipid status.
