Whether 40-year-old can be treated with antihypertensive drugs depends on the patient’s condition. Primary hypertension can control the blood pressure within the normal range, but can not achieve the effect of clinical cure; secondary hypertension can be cured if actively treating the primary disease. If a 40-year-old patient is diagnosed with primary hypertension, he or she needs to take antihypertensive drugs regularly for long-term treatment; usually, after taking antihypertensive drugs, the blood pressure can be controlled within the normal range, but cannot achieve clinical cure; secondly, after stopping the antihypertensive drugs, the blood pressure may increase in a short period of time, which makes it difficult to control the blood pressure. If a 40-year-old patient is diagnosed with secondary hypertension such as pheochromocytoma, cortisolism, primary aldosteronism, etc., and after taking relevant antihypertensive drugs, the blood pressure can be controlled within the ideal range, and at the same time, the primary disease is cured through surgical resection; usually, the clinical cure can be achieved, and after stopping the antihypertensive drugs, the blood pressure will not be elevated. When the above symptoms appear, it is recommended to go to the hospital in time for early and standardized treatment.
