Hyperlipidemia is also known as dyslipidemia in medicine, which may be caused by excessive fat intake, abnormal lipoprotein synthesis and metabolic process, etc. Its harm to human body mainly promotes the occurrence of atherosclerosis, as well as increases the risk of cardiovascular and cerebrovascular diseases, acute pancreatitis, etc. 1.Overview of hyperlipidemia: Lipid is the collective name of various lipid substances in the blood, lipid substances generally cannot be dissolved in the blood The lipids are generally not soluble in the blood, but have to be transported in the blood after binding with apolipoproteins. Since lipids exist in plasma in the form of lipoproteins, dyslipidemia can be manifested as dyslipoproteinemia. In clinical practice, lipid levels are determined by testing four lipid indicators, known as the Lipid Quadruplex. Under normal circumstances, the normal range of total cholesterol is below 5.2 mmol/L, triglycerides is below 1.7 mmol/L, LDL cholesterol is below 3.37 mmol/L as the appropriate range, and HDL cholesterol is above 1.0 mmol/L. If the level of total cholesterol, triglyceride and LDL cholesterol is increased and the level of HDL cholesterol is decreased, it indicates hyperlipidemia; 2. The harm of hyperlipidemia: the main harm is to promote the occurrence of atherosclerosis, of which LDL cholesterol is the key factor of atherosclerosis. If LDL cholesterol is deposited in the subendothelium of blood vessels and engulfed by macrophages, forming foam cells, it will lead to dyslipidemia and then to the formation of atherosclerotic plaques. If the plaque continues to develop, it may lead to luminal narrowing or even occlusion, resulting in more serious diseases such as coronary heart disease and cerebral infarction. In addition to the effects of triglycerides on cardiovascular diseases, they also increase the risk of acute pancreatitis, mostly due to the blockage of the pancreatic ducts by elevated levels of triglycerides in blood lipids, or the obstruction of blood supply in the pancreas. Therefore, for patients with hyperlipidemia, it is recommended to maintain a low-fat diet, eat more fresh vegetables and fruits, such as celery, spinach, grapefruit, watermelon, etc., and avoid greasy and overly sweet foods. At the same time, it is necessary to enhance exercise and exercise, and if necessary, it is recommended to go to the hospital for examination in time and carry out corresponding treatment under the guidance of doctors, such as using statin lipid-lowering drugs like lovastatin tablets, simvastatin tablets, atorvastatin calcium tablets, or cholesterol-lowering drugs like ezetimibe tablets and probucol tablets, to control the blood lipid level to the normal range and thus reduce the risk of inducing other diseases.
