Will I have to be on blood pressure medicine for the rest of my life?

Maybe (not) . . . Forever (and rest of your life) is a very long time/commitment. The question is best addressed by & with your family doc. For instance, how high was/is your blood pressure (BP)? Any other complicating conditions? Can you lower your BP w/lifestyle modifications? Quit smoking! Exercise regularly! Eat healthy! Lose belly fat! Do all that to at least lower dose of meds, maybe drop 1 or more from regim.
