Auntie Zhang, who lives in Jiamusi City, not only ate all kinds of advertised health products to control high blood lipids, but also increased the amount of lipid-lowering drugs on her own. Recently, when she went to the hospital, her cholesterol level had dropped to 4.0 mmol/liter.
Auntie Zhang happily showed her doctor the test results, expecting to be praised, but she was given a serious warning. Her blood lipids were already severely low, and if they continued to drop, she would be at risk of brain hemorrhage at any time.
Lower the Blood Lipid the Better?
More and more people know the bad effects of high blood lipids, and they know that lowering them can reduce the risk of coronary heart disease, myocardial infarction and stroke. But lower blood lipids are not better. Low blood lipid levels are more harmful than slightly high blood lipids.
Lipids are neutral fats in the body, including cholesterol, triglycerides and lipids, which are indispensable physiological substances for the body. Studies have shown that older adults over the age of 70 with cholesterol levels below 4.16 mmol/L are at comparable risk to those with cholesterol levels above 6.24 mmol/L.
Although the incidence of cerebral hemorrhage decreases with decreasing serum cholesterol levels, the incidence of cerebral hemorrhage is instead higher with serum cholesterol below 3.64 mmol/L.
For people without coronary artery disease and other sites of atherosclerosis and without risk factors for coronary artery disease, such as hypertension, diabetes, smoking and family history, the optimal range of total cholesterol is 5.2-5.6 mmol/L and LDL should be less than 3.6 mmol/L.
If there are only risk factors for coronary heart disease, total serum cholesterol should be less than 5.2 mmol/L and LDL should be less than 3.12 mmol/L. Those who already have coronary heart disease should have a total cholesterol of less than 4.68 mmol/L and an LDL of less than 2.6 mmol/L.
Since people often do not feel anything when their blood lipids are elevated or lowered. Therefore, it is recommended that normal people should be checked at least once a year; and people with known dyslipidemia should be checked once every 3-6 months.
In the process of lipid lowering with drugs, do not blindly pursue low cholesterol. Especially, elderly people should be careful in lipid-lowering treatment and just lower it to the appropriate level.
