Generally, young people with a blood pressure value of 140/90 mmHg do not need medication, but they do need medication if their blood pressure is persistently elevated or if they have other comorbidities. A blood pressure of 140/90 mmHg is considered high blood pressure (the American College of Cardiology proposed the diagnostic criteria for high blood pressure as ≥130/80 mmHg in 2017), but it is not in the category of antihypertensive drug therapy. Antihypertensive drug therapy is for: 1. patients with hypertension grade 2 (systolic blood pressure 160~179mmHg and/or diastolic blood pressure 100~109mmHg) or above. 2. Hypertension combined with diabetes mellitus or patients who have developed target organ function damage or complications. 3. Patients with progressive elevation of blood pressure that is not effectively controlled after effective lifestyle intervention. If the blood pressure rises progressively, it is necessary to go to the hospital in time to check whether there is hypertension or other diseases, and if there is a disease, clinical treatment should be carried out in time.
