While secondary hypertension can be cured, primary hypertension is generally not curable and can only be controlled with the help of medication and lifestyle. Primary hypertension cannot be cured at present, but can only be improved with lifestyle intervention and antihypertensive drugs. For example, lifestyle intervention mainly involves controlling body weight, reducing sodium intake, reducing fat intake, quitting smoking and limiting alcohol consumption, increasing exercise and reducing mental stress. Medication should be prescribed by the doctor according to the patient’s physical condition, and the blood pressure should be controlled to <140/90 mmHg. If the elderly group is intolerant, the systolic blood pressure can be controlled to <150 mmHg. Certain secondary hypertension can be triggered by primary aldosteronism, pheochromocytoma, renal vascular hypertension, and renin-secreting tumors. These primary causes can be treated by surgery or other means to cure or improve secondary hypertension. If abnormal blood pressure is detected during home blood pressure measurement or physical examination, it is important to consult a doctor for further examination, identify the cause of the disease, and follow the doctor's instructions for treatment.
