High pressure, also known as systolic blood pressure, is not normal if it is 140 mmHg; low pressure, also known as diastolic blood pressure, is not normal if it is 80 mmHg. With the most widely used criteria for diagnosing hypertension, if a patient’s systolic blood pressure is greater than or equal to 140mmHg and/or diastolic blood pressure is greater than or equal to 90mmHg, the patient is considered to have hypertension. First of all, patients are advised to quit smoking and drinking, have a low salt and low fat diet, work and rest regularly, avoid straining and staying up late, and exercise to lose weight in order to better reduce blood pressure. If after 1-3 months of lifestyle adjustment, blood pressure still does not fall within the standard range, you can take antihypertensive drugs to assist in lowering blood pressure.
