Hyperlipidemia can cause dizziness. Hyperlipidemia involves the deposition of lipids on the endothelial lining of blood vessels, which is a primary consequence of abnormal blood lipids. This can lead to the onset and progression of atherosclerosis. For instance, low-density lipoproteins tend to deposit on arterial walls and are ingested by mononuclear giant cells. This situation can lead to arteriosclerosis, such as atherosclerosis of the cervical and intracranial arteries. This condition can result in insufficient blood supply to the brain, thereby causing dizziness. Therefore, hyperlipidemia can indeed cause dizziness.
