There is no clinical diagnosis of so-called thick blood. Generally, the term thick blood refers to hyperlipidemia, which in itself does not cause dizziness, but if it leads to atherosclerosis or even stenosis of the cerebral arteries, it can cause inadequate blood supply to the brain. When the blood supply to the vertebrobasilar system is insufficient, the patient may show signs and symptoms of cerebellar and brainstem ischemia and hypoxia, dizziness, nausea, vomiting, balance disorder and ataxia, and patients with severe cerebral insufficiency may cause cerebellar and brainstem infarction, and the symptoms are usually persistent, with hypodense lesions on cranial CT. Patients with hyperlipidemia should be given active control, and statins are generally given clinically, such as simvastatin, resulvastatin or atorvastatin, to regulate lipid and stabilize plaque treatment, and should also be given to improve blood circulation treatment, and the commonly used drugs are mainly Ginkgo biloba drops and brain heart pass, etc.
