Diabetes is known as a critical condition such as coronary heart disease, commonly combined with dyslipidemia and atherosclerosis often exists. However, there are often patients who take a paper lipid test without arrows and tell their doctors, “My blood lipids are normal, is there no need for lipid-lowering medication? In today’s generally more expensive lipid-lowering drugs, this problem is really troubling many patients. 1, we must first clarify the test list “normal”, whether the blood lipids are really normal. In the general healthy population, whether the blood lipid is normal can refer to the reference range on the test, but for diabetic patients, the reference standard is different, generally we think that LDL level higher than 2.6mmol/l is abnormal. Therefore, the results look at the arrow is not reliable. 2.Without any discomfort and without medication the lipid test has been in the ideal attainment range Does it need lipid-lowering medication? Existing medical research has made it clear that diabetes mellitus over the age of 40 can benefit from lipid-lowering therapy with statins regardless of whether there are dyslipidemia (long-term reduction of mortality from heart attacks, cerebrovascular accidents and other causes), and diabetes mellitus (adults) under the age of 40 can benefit if they have dyslipidemia, overweight or obesity, hypertension, smoking, family history of early-onset cardiovascular disease (coronary heart disease, cerebrovascular accidents), or already have coronary heart disease, cerebrovascular accident, etc., the use of statins for lipid lowering may also benefit. Therefore, statin therapy is recommended for all diabetics over 40 years of age and those under 40 years of age (adults) with risk factors; those under 40 years of age without the above risk factors may be temporarily excluded. 3.If my blood lipid level was high before, but it was lowered after treatment, do I need to continue lipid-lowering drug treatment? Maintenance of lipid-lowering drug therapy can provide long-term cardiovascular benefits, while discontinuation of the drug increases the risk. 4.How should I choose lipid-lowering drugs? Lipid-lowering drugs should be selected with reference to the type of dyslipidemia and clinical conditions such as liver and kidney function, but generally long-term treatment regimens need to contain statins, which are the only drugs with clear cardiovascular benefits when used alone. 5.Do lipid-lowering drugs have side effects? The so-called side effects are conditions that may occur but do not necessarily happen, and generally have a low probability. The main serious adverse reactions of statins are rhabdomyolysis and liver injury, which can generally be recovered after stopping the drug, both rare, and have been used by hundreds of millions of people worldwide, with excellent safety and extremely low risk of observing symptoms such as muscle aches and pains. In summary, we can see that in diabetes, the use of lipid-lowering drugs actually does not depend on whether the blood lipids are high, but rather on whether the cardiovascular risk is dangerous, and the purpose of lipid-lowering is firstly to prevent the disease, and secondly to cure it. For all chronic diseases, the earlier the prevention and treatment, the better the effect and the lower the cost. Of course, do not forget that the basis of lipid-lowering treatment is reasonable diet, exercise and weight control.
