Diabetic patients often pay attention to controlling blood glucose, but neglect lipids. In fact, blood lipids are a very dangerous factor to induce further deterioration of diabetes and accelerate the vascular and neurological lesions in diabetes. In recent years, it has been confirmed that elevated blood lipids are also one of the causes of diabetes, so it is now called glycolipidosis abroad. If diabetic patients adhere to a low-fat diet and reduce their fat intake to a lower level, for example, by reducing the calories provided by fat intake from 40% to l0%, diabetes will be better controlled. A high percentage of people with type 2 diabetes get more than 30% of their calories from fat. In fact, most Westerners prefer to consume high-fat foods, which is the main reason why more Westerners have diabetes. That’s why it’s important for people with diabetes to not only control their blood sugar, but also to monitor their blood lipids regularly. So how often should blood lipids be measured? (Includes LDL-C: low-density lipoprotein cholesterol; HDL-C: high-density lipoprotein cholesterol; TG: triacylglycerol. TC: total serum cholesterol) ① For patients whose lipids are within the normal range: if there are no other cardiovascular risks, a lipid profile should be performed at least once a year. ②If accompanied by multiple cardiovascular risk factors (men ≥40 years or postmenopausal women, smoking, obesity and family history of early-onset ischemic cardiovascular disease, etc.), monitor lipid profile once every 3 months. (iii) If hyperlipidemia, the lipid profile was monitored every 1 to 3 months during the initiation of lifestyle intervention and drug therapy, and drug dose adjustment, and every 3 to 12 months thereafter. The lifestyle interventions mentioned here are: 1. adjusting the diet structure, including controlling total calories, reducing the intake of saturated fatty acids, increasing the intake of unsaturated fatty acids, controlling the intake of cholesterol, and increasing foods rich in vitamins and fiber. 2, maintain a healthy lifestyle: including weight loss, quit smoking, control alcohol, limit salt, adhere to aerobic exercise, focus on mental health, maintain an optimistic and open-minded attitude to life. Diabetic patients, mostly combined with hyperlipidemia, need statin drugs to lower lipid therapy. Of course, the application of lipid-lowering drugs, the dose and the duration of application should be carried out according to the doctor’s advice, but there are some precautions: 1. Statins should be taken at night: the liver synthesizes cholesterol mainly at night, and statins work mainly by inhibiting the synthesis of cholesterol, so that the best lipid-lowering effect can be obtained. 2. Attention should be paid to monitoring liver function and muscle enzymes before and during medication: because statins can lead to liver damage and myositis, the occurrence of which is related to the dose of medication. The combination of statins and beta drugs can significantly increase the toxic side effects of the drugs, especially the risk of rhabdomyolysis, so the combination of the two drugs is generally not recommended. Even if the condition does require the combination of the two, the respective dosage should be reduced, and taken separately in the morning and evening (generally recommended: take beta in the morning and statins in the evening) to reduce the risk of side effects. 4.It often takes one or two weeks or even longer for lipid-lowering drugs to take effect, so lipid-lowering drugs should not be rushed or changed frequently. 5.After the blood lipid is reduced to normal, you should not stop the medication. Once the drug is stopped, high blood lipids will rise again and rebound. In principle, as long as there are no serious adverse reactions, lipid-lowering drugs should be taken for a long time, only in this way can cardiovascular benefits be achieved. 6. To correct the disorder of lipid metabolism, we cannot rely entirely on lipid-lowering drugs, but also pay attention to lifestyle intervention and treatment of the primary disease (i.e. diabetes). In fact, some type 2 diabetic patients with mainly elevated triglycerides, after the ideal control of blood sugar, lipids also returned to normal. 7, lipid test results in the normal range of the laboratory test does not necessarily mean that lipid control standards. This is because the low-density lipoprotein cholesterol on the test is based on the standard of normal people, but according to various guidelines at home and abroad, for patients at high risk of cardiovascular disease, very high risk, their lipid control should be more stringent than normal people, respectively, should be controlled at 2.6 mmol / L, 1.8 mmol / L below.
