@wangning - I can certainly understand your concern about side effects of long term medication treatment. I've been on several different high blood pressure medications for over 40 years. Back in my 50s I was fortunate enough to be involved in a Mayo Clinic heart study. As a result my diagnosis changed to hypertension caused by primary hyperaldosteronism and my medications were changed to spironolactone - 25mg and hydrochlorothyazide - 25mg. I've made some lifestyle changes since then to help control the hypertension and possibly get off the meds but I don't think that will happen for me but I'm still doing what I can do to help the condition. Here's some information on the topic that you might find helpful.

Have you discussed how you can better manage your hypertension with your doctor?
