A blood pressure of 142/88 mmHg is not normal, as long as the systolic blood pressure exceeds 140 mmHg or the diastolic blood pressure exceeds 90 mmHg, the diagnostic criteria for hypertension are met when measured in a quiet state. The patient’s current systolic blood pressure has exceeded 140 mmHg, so it is hypertension, which is a critical elevation of blood pressure. Therapeutic lifestyle intervention is an option if it is caused by obesity, smoking, alcohol consumption, or prolonged sedentary lifestyle and lack of exercise. Such people can reduce their weight by adhering to regular exercise, limiting sodium and fat intake, and consuming more fruits and vegetables appropriately, which can lower their blood pressure to within the normal range. However, if the patient has secondary hypertension due to other causes, or if the blood pressure does not decrease consistently after lifestyle improvement, medication needs to be applied.
