What causes frequent dizziness and blurred vision?

Dizziness and visual blurring are common clinical symptoms that may be caused by various factors: 1. Hypotension or orthostatic hypotension: When standing up suddenly from a sitting or lying position, blood cannot be rapidly supplied to the brain, leading to transient cerebral ischemia. 2. Hypoglycemia: Insufficient glycogen reserves in the body result in inadequate energy supply, which can cause dizziness and visual blurring. 3. Cerebral hypoperfusion: Cerebrovascular disease may lead to reduced vascular elasticity and narrowed vessel lumen, resulting in insufficient blood supply to the brain and causing dizziness and visual blurring. 4. Anemia: A deficiency in red blood cell count or hemoglobin levels impairs oxygen transport, causing cerebral hypoxia. 5. Cervical spine disease: Lesions in the cervical spine may compress the carotid artery, affecting blood supply to the brain and causing dizziness and visual blurring. 6. Heart disease: Conditions such as arrhythmia and heart valve disease may reduce cardiac pumping function, impairing cerebral blood supply. If this condition occurs frequently and significantly affects daily life, prompt medical attention is recommended.
