The treatment of hypertension includes drug treatment and non drug treatment. Non drug treatment mainly refers to the improvement of lifestyle, such as weight control, reduction of salt and fat intake, smoking cessation and alcohol restriction, and reduction of mental stress. Drug treatment is mainly aimed at patients with hypertension of grade II or above, or patients with multiple system complications. Generally, blood pressure should be controlled below 140/90 mm Hg. For patients with chronic diseases such as diabetes, kidney disease, heart failure, etc., blood pressure can be controlled below 130/80 mm Hg. For the selection of antihypertensive drugs, it is generally necessary to start from a small dose and give priority to long-acting preparations, which can be used in combination. Specific drugs should be selected according to the patient's specific condition and tolerance. Some patients with secondary hypertension need to actively treat the primary disease.
