The higher the blood pressure and the longer it lasts, the more severe the lesion. The arterial lesions are mainly glassy lesions in the walls of the small arteries of the bulb, as well as thickening of the intima of the walls of the interlobular and arcuate arteries, which cause ischemic renal parenchymal damage. The following is the prevention method of glassy lesions in small arteries: 1, reasonable diet, limit sodium intake First of all, we should reduce the salt used for cooking, the amount of salt per person per day should not exceed 6g. Reduce dietary fat, supplement the right amount of protein, eat more vegetables and fruits, intake of sufficient potassium, magnesium, calcium. Limit alcohol consumption, alcohol intake is linearly correlated with blood pressure level and the prevalence of hypertension, hypertensive patients should abstain from alcohol or strictly limit. 2, reduce weight Weight gain is closely related to hypertension, hypertensive patients with lower weight is beneficial to improve insulin resistance, diabetes, hyperlipidemia and left ventricular hypertrophy. It can be achieved by reducing the daily calorie and salt intake and enhancing physical activity. 3, exercise Exercise can not only reduce systolic and diastolic blood pressure (6-7mmHg), but also be beneficial to reduce weight, increase physical strength and reduce insulin resistance. You can choose different ways such as jogging, brisk walking and tai chi according to your age and physical condition. Exercise frequency is generally 3 to 5 times a week, each lasting 20 to 60min. 4, qigong and other bio-behavioral methods Qigong is a traditional health care method in China, through the induction of ideas and breath adjustment to play a self-adjustment role. Long-term qigong exercise can lead to better blood pressure control, reduce the amount of antihypertensive drugs, and can reduce the incidence of stroke. 5, other aspects Maintain a healthy mental state, reduce mental stress and depression, quit smoking, etc. are very important for patients with hypertension.
