Hyperlipidemia is an important factor in causing cardiovascular diseases. There are no obvious symptoms in the early stage, and symptoms such as dizziness and weakness, insomnia and forgetfulness, chest tightness and palpitations appear only in the late stage. Serious complications such as angina pectoris, myocardial infarction and stroke can occur in the late stage. According to Chinese medicine, hyperlipidemia is mainly characterized by heavy limbs, dizziness and other symptoms, which are classified by modern doctors as “phlegm”, “dampness”, “chest paralysis” and “vertigo”. Modern medical practitioners classify it under the categories of “phlegm evidence”, “dampness obstruction”, “chest paralysis” and “vertigo”. Hyperlipidemia is insidious, and there are no obvious clinical symptoms in the early stage, and many patients only find elevated lipids when they have blood tests. Due to the elevated lipids in the blood, the blood becomes sticky and lipids are deposited on the walls of blood vessels, forming atherosclerotic plaques and causing arterial narrowing, which will cause symptoms of cerebral blood supply deficiency when it affects the cerebral arteries, such as dizziness and headache, fatigue and insomnia, and memory loss. If the cerebral artery is occluded or the arterial plaque is dislodged to form cerebral artery embolism, it will cause symptoms of cerebral infarction, such as distorted mouth and numbness of limbs. If the coronary artery is narrowed due to high blood lipid, it will cause insufficient blood supply to the heart muscle and symptoms such as chest tightness, shortness of breath, panic, chest pain and weakness. In the late stage, serious complications such as angina pectoris and myocardial infarction may occur. High lipid deposition to the liver can cause fatty liver and liver cirrhosis.
