The hazards of high blood lipids can be summarized as the hazards of cardiovascular and cerebrovascular systems and the hazards of non-cardiovascular and cerebrovascular systems. The harm of cardio-cerebral vascular system, such as atherosclerosis, which leads to cardio-cerebral vascular chronic diseases; non-cardio-cerebral vascular system harm, including fatty liver, pancreatitis and so on. 1. Cardiovascular and cerebrovascular system diseases: mainly atherosclerosis-induced cardiovascular and cerebrovascular chronic diseases, such as hypertension, coronary heart disease, stroke and so on. The fat and cholesterol content in human blood is too high, accumulating in the inner wall of blood vessels will gradually form atherosclerosis, leading to narrowing or blockage of the lumen of blood vessels, affecting the coronary arteries, carotid arteries, vertebral arteries, leading to myocardial infarction, cerebral infarction and other diseases. 2. Non-cardiovascular and cerebrovascular system diseases: such as fatty liver, pancreatitis and so on. The high content of fat in the blood vessels of the body and the accumulation of part of the fat in the liver will increase the burden on the liver, increase the prevalence of fatty liver, and cause liver cirrhosis with impaired liver function. Excessive blood fat can also lead to pancreatic ischemia or even necrosis , inducing acute pancreatitis. High blood fat is harmful to the human body, diagnosis of high blood fat should be under the guidance of the doctor medication, such as atorvastatin, resuvastatin and so on.
