If the patient’s blood pressure is high and then low, high and low, it is recommended that the patient can have an ambulatory blood pressure monitoring to assess the overall blood pressure situation for 24 hours, and when this abnormal performance occurs, we should first rule out secondary hypertension. For example, if the patient has adrenal gland occupancy, renal vascular stenosis, or cranio-cerebral occupancy, CT of the adrenal gland, CT of the cranio-cerebral gland, and ultrasound of the renal vasculature can be performed, and blood tests for hypertension can also be done. If the possibility of secondary hypertension is ruled out, then it is necessary to clarify whether the patient has anxiety disorders or disorders of plant nervous function. For some menopausal women or people with psychiatric disorders, the blood pressure is often high and low, which is difficult to control with medication, and should be combined with treatment to improve anxiety and mood, which will help to make the blood pressure more stable.
