Primary hypertension is not completely curable in most people. In contrast, some secondary hypertension can be cured. The cause of primary hypertension is not fully understood and is currently thought to be related to genetic and environmental factors. Therefore, even with a healthy lifestyle, such as watching your diet, exercising more, and controlling your weight, it is difficult to avoid the development of hypertension, but a healthy lifestyle will result in a later onset or less severe hypertension. The cause of secondary hypertension is clearer, for example, hypertension caused by renal artery stenosis, which can be restored to normal by removing the stenosis. Primary hypertension accounts for more than 90% of hypertension, and its main danger lies in the effects on the heart, brain, kidneys and other vital organs. Therefore, although hypertension cannot be completely eradicated from its cause, controlling blood pressure can minimize the overall risk of death from cardiovascular and cerebrovascular complications, so as long as this goal can be achieved through medication, it is fine. Hypertension medications generally cannot be stopped at will, for example, metoprolol can appear to stop, so generally after taking antihypertensive medications, even if the blood pressure is well controlled, you still need to continue to take the medication, and if you want to reduce the dosage or discontinue it, the advice of a professional doctor should prevail.
