When the blood pressure is lowered and the patient still feels dizzy, there are several situations: 1. The blood pressure is lowered so fast that the patient’s cerebral blood vessels are not regulated, so dizziness will still occur. When the blood pressure is lowered too quickly, the patient does not adapt to the low blood pressure and becomes dizzy, which is actually an indirect response to the lack of blood supply to the cerebral arteries; 2. After the blood pressure is lowered, the patient still feels dizzy, which is not actually caused by hypertension. In clinical practice, many patients with hypertension do not have any clinical symptoms because they have no symptoms and do not think about checking their blood pressure, so even if the blood pressure is lowered, some patients still feel dizzy; 3, other causes, such as cerebral infarction, cerebral artery insufficiency, Meniere’s syndrome, etc., cause dizziness due to these diseases, and when they are combined with hypertension, even if the blood pressure is lowered, the patient will still The clinical manifestation of dizziness will be present even if the blood pressure is lowered.
