Is dizziness a sign of low blood pressure?

Not necessarily. Dizziness can be a symptom of many underlying medical conditions, including both high blood pressure and low blood pressure. Dizziness is caused by disrupted function in the inner ear or the brain, and can be caused by factors such as dehydration, anxiety, medication side effects, or sudden movements (such as standing up quickly). It's important to consult a healthcare professional to determine the specific cause of dizziness and receive an accurate diagnosis and appropriate treatment.
