Hypertension and hypotension are judged mainly based on blood pressure values, hypertension is defined as systolic blood pressure greater than 140 mmHg or diastolic blood pressure greater than 90 mmHg, as long as one of the standards can be diagnosed as hypertension, hypotension is defined as blood pressure less than 90/60 mmHg, both blood pressure values are measured in the patient’s quiet state, without oral antihypertensive drugs after a standard blood pressure monitor to measure. For both hypertensive and hypotensive people in general, attention should be paid, especially for hypertensive people due to the increase of blood pressure, long-term will lead to atherosclerosis, renal insufficiency or fundus lesions, etc., easily lead to complications, especially need drug treatment and lifestyle intervention. For hypotension, many people are related to genetic or physical factors, and generally do not require special treatment, only regular observation.
