A systolic blood pressure of 158 mmHg is considered mild hypertension, which is not particularly serious, while a diastolic blood pressure of 158 mmHg is considered severe hypertension and should be seen immediately. Hypertension is diagnosed in adults older than 18 years of age when systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg are measured on three occasions not on the same day without the use of antihypertensive medication. In general, hypertension can be divided into three levels, mild hypertension is defined as systolic blood pressure in the range of 140-159mmHg and/or diastolic blood pressure in the range of 90-99mmHg; systolic blood pressure in the range of 160-179mmHg and/or diastolic blood pressure in the range of 100-109mmHg is referred to as moderate hypertension; and systolic blood pressure ≥180mmHg and/or diastolic blood pressure ≥110mmHg hypertension is referred to as moderate hypertension. 110mmHg is called severe hypertension. If the diastolic blood pressure is 158mmHg, the patient should seek medical treatment; if the systolic blood pressure is 158mmHg, it is mild hypertension, which can be treated by therapeutic lifestyle intervention, and if the blood pressure is poorly controlled or combined with other complications, antihypertensive medications should be used under the guidance of a specialist.
