In China’s diagnosis of hypertension, the diagnosis of hypertension is that if an adult’s systolic blood pressure exceeds 140 mmHg or diastolic blood pressure exceeds 90 mmHg in a quiet state and without oral antihypertensive medication, the patient can be diagnosed with hypertension if his or her blood pressure reaches one of the indicators for the first time. However, people diagnosed with hypertension must go to a standardized hospital for diagnosis. The most standardized diagnosis of hypertension is the average of three measurements of blood pressure on the same day, and if the first diagnosis of hypertension is Grade II hypertension, that is, systolic blood pressure over 160 mmHg or diastolic blood pressure over 100 mmHg, medication should be started immediately, and the cause should be sought. For Grade II hypertension or below, that is, between 140/90mmHg and 160/100mmHg, appropriate lifestyle adjustments can be made. If the blood pressure cannot be brought down to normal after lifestyle adjustments, oral medication is recommended.
