Hyperlipidemia is defined as high cholesterol and/or triglycerides or low HDL cholesterol in the blood, which is called dyslipidemia in modern medicine. It is one of the independent risk factors of cardiovascular diseases and also a metabolic disease that affects the whole body. What are the hazards of hyperlipidemia? The early stage of hyperlipidemia will lead to dizziness, forgetfulness, loss of energy, sleep disturbance, chest tightness and shortness of breath, etc. The development to the middle and late stage will lead to the following hazards: 1) blood: increase blood viscosity, slow down blood flow; 2) heart: atherosclerosis, coronary heart disease, angina pectoris, myocardial infarction; 3) brain: cerebral thrombosis, cerebral hemorrhage; 4) kidney: renal insufficiency, renal failure; 5) liver: fatty disease, etc. 5, liver: fatty liver, cirrhosis; 6, eyes: impaired vision, or even blindness. In general, patients with a family history of hyperlipidemia, as well as patients with hypertension, diabetes, fatty liver, obesity, long-term smokers and alcoholics are prone to suffer from hyperlipidemia. In addition, men over 40 years old, post-menopausal women, those who lack exercise, those who have a long-term high-fat and high-sugar diet, and those with cardiovascular diseases are all at high risk of hyperlipidemia. How to prevent hyperlipidemia?
