What causes dizziness?

Dizziness is a common symptom that can be caused by various factors, mainly including: 1. Insufficient cerebral blood supply: Cerebrovascular diseases, cervical spondylosis, and other conditions can lead to inadequate blood supply to the brain, resulting in dizziness. 2. Hypoglycemia: Insufficient intake or excessive consumption of sugar in the body can cause low blood glucose levels, leading to dizziness. 3. Abnormal blood pressure: Both hypertension and hypotension can affect cerebral circulation and cause dizziness. 4. Anemia: A deficiency in the number or quality of red blood cells in the blood leads to inadequate oxygen supply, causing dizziness. 5. Neurological disorders: Conditions such as brain injury, epilepsy, and cerebral ischemia can cause abnormal nervous system function, resulting in dizziness. In addition, prolonged overexertion, lack of rest, and dehydration can also cause dizziness. If dizziness occurs frequently, prompt medical attention is recommended.
