High blood lipids by themselves do not cause dizziness, but patients with high blood lipids generally have increased blood viscosity and slow blood flow, which can easily cause atherosclerosis. In atherosclerosis, the lumen is narrowed, the walls are stiff, and the blood vessels are less elastic, which can easily cause insufficient blood supply to the brain. Insufficient blood supply to the cerebellum and brainstem allows patients to experience dizziness, nausea, vomiting, balance disorders and ataxia. In the case of cerebral insufficiency of blood supply, patients usually present with episodes of lateralized limb sensory disturbances and motor disturbances, and may also experience blackness in front of the eyes. In severe insufficiency of blood supply, it may cause cerebral infarction, and in patients with cerebellar and brainstem infarction, dizziness may also occur. If patients have hyperlipidemia, they should be given promptly adjusted treatment. Statins are generally preferred clinically, and commonly used drugs include simvastatin, resulvastatin and atorvastatin. Clinically, lipids mainly include cholesterol, triglycerides, high-density lipoprotein and low-density lipoprotein. Elevated lipids generally refer to elevated cholesterol, triglycerides and LDL.
