Blood pressure's down. Still dizzy. What's going on?

This symptom may be caused by dizziness caused by a relatively rapid drop in blood pressure, and cannot be ruled out as other reasons, such as cerebrovascular disease, lack of sleep, etc. When lowering blood pressure, you must take antihypertensive drugs according to doctor's advice, and you cannot increase or decrease the dosage at will. Daily attention should also be paid to dietary regulation. Foods with high salt content cannot be eaten.
