Hypertension is a common disease that is clinically almost asymptomatic, with headaches as the only finding. Many people think that hypertension is not a major disease and often leave this disease alone, or take medication when they want to, and forget about it afterwards. In fact, hypertension is quite harmful, and many common cardiovascular diseases are caused or induced by it, such as stroke, coronary heart disease, myocardial infarction and so on. With the progression of the disease, the persistent increase in blood pressure often causes damage to the heart, brain, kidneys and other organs. Therefore, the prevention and control of hypertension is of great significance. (1) First of all, salt intake should be limited. Salt (i.e., sodium chloride) and hypertension are closely related, high sodium intake can make blood pressure rise while low sodium intake can lower blood pressure, so suffering from hypertension, must maintain a light diet, not more than 6g of salt per day. (2) appropriate exercise. Perform exercises suitable for your condition, such as walking, running, swimming, tai chi, etc. The benefit of exercise is to reduce body weight, which leads to a decrease in blood volume and vascular reactivity. In addition, exercise can also enhance cardiac function and reduce sympathetic nerve activity, which can benefit people. (3) Anti-hypertensive drug therapy. It should be applied under the guidance of a doctor, with regular blood pressure measurement and timely adjustment of the dose and class of antihypertensive drugs. The general principle is: take medication for a long time and choose oral medication with mild, slow and long-lasting antihypertensive effect, little side effects and easy to use. If an antihypertensive drug is not effective, it can be used in combination, the most common is the combination of angiotensin converting enzyme inhibitors (Kepone, Asterix, etc.) and beta-blockers (Jinan, Betalactam, etc.), diuretics (dihydroketuria, tachyphylaxis) and beta-blockers, etc. Start with a small dose, gradually increase the dose, after achieving the purpose of lowering blood pressure, can be changed to maintenance amount to consolidate the efficacy. In addition, for patients whose blood pressure has increased significantly for many years, it is not advisable to make the blood pressure fall too much or too fast, as patients often feel uncomfortable because they cannot adapt, and too low blood pressure can also lead to cerebrovascular accidents.
