Hyperlipidemia is one of the common diseases among middle-aged and elderly people, and it is also a disease that attracts much attention and seriously affects the normal life of middle-aged and elderly people. Lipids are lipids contained in plasma or serum, including cholesterol (CH), triglycerides (TG), phospholipids (PL) and free fatty acids (FFA). Cholesterol is subdivided into cholesteryl esters and free cholesterol, which add up to total cholesterol (TC). Lipids combine with apolipoproteins to form lipoproteins soluble in plasma for transport and metabolism. Lipoproteins are divided into celiac, very low density lipoproteins, low density lipoproteins, medium density lipoproteins, and high density lipoproteins according to differences in composition, density, and characteristics, using electrophoresis and ultracentrifugation. Classification Hyperlipidemia can be divided into two categories: primary and secondary. Primary hyperlipidemia is related to congenital and genetic. Secondary hyperlipidemia is mostly secondary to metabolic disorders (diabetes mellitus, hypertension, mucous edema, hypothyroidism, obesity, hepatic and renal diseases, hyperadrenocorticism), or related to other factors (age, sex, season, alcohol consumption, smoking, diet, physical activity, mental stress, emotional activity). Third, treatment For the treatment of hyperlipidemia, many doctors and patients always hope for drugs. In fact, drug treatment is only one aspect. More important is exercise and dietary lipid regulation, which is the fundamental part of our solution to hyperlipidemia. The following is a brief description of the treatment of hyperlipidemia. 1, exercise treatment exercise and physical activity can make triglyceride levels drop significantly. Therefore, patients with hypertriglyceridemia should also engage in long-term, regular physical exercise or physical labor. In principle, all types of hyperlipidemia are suitable for exercise therapy, but individualized and targeted exercise prescription should be formulated according to the specific situation. The purpose of exercise therapy is to fight against exercise deficiency, maintain and enhance the ability to exercise, improve body metabolism and promote health. Exercise is contraindicated in the following cases: hyperlipidemia combined with various acute infections, fever, recent electrocardiogram changes or acute myocardial infarction, unstable angina pectoris, uncontrolled arrhythmia, Ⅲ degree atrioventricular block, congestive heart failure, uncontrolled hypertension, diabetic acidosis, gangrene of the lower extremities, severe hypothyroidism, renal insufficiency, and so on. Dietary treatment Dietary treatment: light diet, less greasy; less intake of animal offal; fish, shrimp and crab can not be more; lean meat, fish and vegetable oil, normal eating to lower blood fat.
