The need to take medication for high blood pressure of 160mmHg and low pressure of 90mmHg is determined by the results of blood pressure monitoring. When the blood pressure is measured three or more times in a quiet state on a different day, if the blood pressure is around 160/90mmHg on all three occasions, medication is required; if the above conditions are not met, hypertension cannot be diagnosed, no medication is required, and regular monitoring of blood pressure is needed. When the blood pressure is measured three times not on the same day, all have systolic blood pressure (high pressure) ≥140mmHg or diastolic blood pressure (low pressure) ≥90mmHg, then it can be diagnosed as hypertension; if it fails to meet the above conditions, it can’t be diagnosed as hypertension, and it may be the effect of emotional excitement, after exercise, etc., no need for oral antihypertensive medication, and regular monitoring of blood pressure is required. When the diagnostic conditions of hypertension are met, if the systolic blood pressure is ≥160mmHg or (and) the diastolic blood pressure is ≥100mmHg, it can be diagnosed as hypertension grade 2, and oral antihypertensive medication is needed for treatment; in this case, the blood pressure of high pressure of 160mmHg and low pressure of 90mmHg can be diagnosed as hypertension grade 2, and medication is needed for treatment. Diuretics, beta receptor antagonists, calcium channel blockers, angiotensin-converting enzyme inhibitors and angiotensin receptor antagonists can be used for antihypertensive treatment according to the individual’s physical condition, such as hydrochlorothiazide, metoprolol, amlodipine, captopril, valsartan, and other medications, which need to be used under the guidance of a doctor. When diagnosed with hypertension grade 2, oral antihypertensive drugs are required, and you need to go to the hospital and follow the doctor’s instructions for medication.
