Elevated blood pressure, if it meets the diagnostic criteria for hypertension, needs to be treated from the following aspects: First, dietary control, including low salt diet, salt intake should be less than 6 grams per day, avoid excessive intake of saturated fatty acid food, appropriate food rich in K+ and Ca+2. Second, quit smoking and limit alcohol. Third, weight control, weight control in the normal range, conducive to blood pressure control. Fourth, the use of antihypertensive drugs, including the commonly used five major classes of antihypertensive drugs. If blood pressure is elevated and does not reach the diagnostic criteria for hypertension, i.e., systolic blood pressure is between 130-140 mmHg and diastolic blood pressure is between 80-90 mmHg, it can be called critically elevated blood pressure. This is a time when non-pharmacological treatment such as diet and exercise can be administered first and blood pressure monitored. In addition, if the blood pressure is too high and causes hypertensive crisis such as stroke, cerebral hemorrhage, myocardial infarction, aortic coarctation, etc., it is necessary to go to the nearest hospital immediately for specialist guidance and treatment to save lives.
