Food does not have the effect of lowering blood pressure. Patients with high blood pressure should control their blood pressure through healthy lifestyle and oral antihypertensive drugs. 1. Healthy lifestyle: patients with hypertension need to make dietary adjustments, such as paying attention to reducing salt intake, not excessive intake of high-fat foods, suggesting patients with hypertension to eat more vegetables, appropriate physical exercise, and maintain a balanced and happy mind. Although diet is equally important for hypertension, no food has an obvious antihypertensive effect and cannot be used as the main way of treatment to lower blood pressure. 2. Oral antihypertensive drugs: patients with high blood pressure have regular oral antihypertensive drug treatment on the basis of dietary lifestyle, antihypertensive drugs include five categories, such as calcium antagonist amlodipine, beta-blocker metoprolol, angiotensin-converting enzyme inhibitor Benadryl, angiotensin II receptor antagonist Irbesartan, diuretics hydrochlorothiazide and so on. Patients with high blood pressure should choose appropriate antihypertensive drug therapy under the guidance of a doctor, and at the same time develop a healthy lifestyle, and should not expect to achieve the effect of lowering blood pressure simply by controlling their diet.
