Blood pressure of 140mmHg is already considered high. The normal range of blood pressure in normal adults in a quiet state is 90-139mmHg systolic, 60-89mmHg diastolic, and hypertension is defined as a systolic blood pressure of ≥140mmHg and/or a diastolic blood pressure of ≥90mmHg without the use of antihypertensive medication. so a systolic blood pressure of 140mmHg is already considered high. Very few people have a diastolic blood pressure as high as 140 mmHg. The diagnosis of hypertension is that three measurements of systolic blood pressure ≥140mmHg and/or diastolic blood pressure ≥90mmHg on a different day are generally required for the diagnosis of hypertension. If only one systolic blood pressure of 140 mmHg is not enough to diagnose hypertension, multiple blood pressure monitoring is required. If the diagnosis of hypertension is reached, it is necessary to consult a doctor in time and take the next step under the guidance of a physician, and do not take any unauthorized treatment.
