What causes dizziness and blurred vision?

Dizziness and blacking out may be caused by the following reasons: 1. Hypotension or hypoglycemia: Low blood pressure or decreased blood glucose levels can lead to insufficient blood supply to the brain, resulting in dizziness and temporary vision darkening. 2. Anemia: A reduced number or impaired function of red blood cells decreases the blood's oxygen-carrying capacity, potentially causing dizziness and visual blackouts. 3. Cervical spondylosis: Cervical spine problems may compress blood vessels and nerves, impairing cerebral blood flow and nerve conduction, thereby leading to dizziness and vision darkening. 4. Medication effects: Certain drugs may affect the nervous and cardiovascular systems, causing dizziness and transient visual darkening. 5. Other causes: These include arrhythmias, cerebrovascular diseases, and other conditions that may also trigger symptoms of dizziness and visual blackouts.
