Primary hypertension is mainly treated by lifestyle intervention and antihypertensive drugs; secondary hypertension, mainly by treating the primary disease, can be cured in some patients. Hypertension is categorized into two types: primary hypertension and secondary hypertension. Primary hypertension is the most important risk factor for cardiovascular and cerebrovascular diseases, often coexisting with other cardiovascular risk factors, and can damage the structure and function of vital organs, such as the heart, brain, and kidneys, and ultimately lead to the failure of these organs. Secondary hypertension is defined as elevated blood pressure caused by some identified disease or etiology. For primary hypertension, the two main approaches are lifestyle intervention and medication, which require lifelong treatment. Secondary hypertension, on the other hand, requires symptomatic treatment of related diseases, such as aortic valve insufficiency, craniocerebral lesions, glomerulonephritis, and other causes, in addition to lifestyle interventions. The first step in the treatment of hypertension is to make a clear diagnosis, choose different treatment programs according to different types, and follow the doctor’s instructions for medication.
