Low blood pressure, also known as diastolic blood pressure, is abnormal if it is 92 mmHg after measurement at rest, and this condition is classified as first-degree hypertension, which is often referred to as mild hypertension. If the patient himself is overweight or obese, he may not start antihypertensive drug treatment first. Patients are advised to start with lifestyle intervention treatments, such as exercise for weight loss, smoking and alcohol cessation, and low-salt and low-fat diets. It is likely that after improvement through good lifestyle interventions, blood pressure gradually returns to normal and there is no need for oral antihypertensive medication. If the patient’s blood pressure is still around 92 mmHg diastolic after 1-3 months of overall lifestyle intervention improvement, the patient is advised to take a weaker antihypertensive medication. It is relatively safe to try to control the diastolic blood pressure above 65mmHg and below 90mmHg.
