The most widely used criteria for diagnosing hypertension are systolic blood pressure (140 mmHg) and diastolic blood pressure (90 mmHg), which are measured three times on the same day. For patients with hypertension, they must pay attention to exercise and weight loss, quit smoking and alcohol, and have a low-salt, low-fat diet on weekdays. Also keep a calm mind and eat more fresh fruits and vegetables so that the blood pressure can be better controlled. If the patient is found to have hypertension for the first time, it is important to further identify whether the current blood pressure is primary or secondary hypertension. For primary hypertension, lifelong, long-term treatment with oral antihypertensive drugs is generally required.
