And it could skyrocket for example if you get into a stressful situation. And you wouldn't notice that you are over 180+. And one day you get a stroke and become paralyzed. Sure, do not take the medication. These exists since the 40s, there is nothing wrong with them.
The doctors will remove medication when the blood pressure goes down. You are literally supposed to take them only when the pressure is actually high.
Do you have a well-regarded source that recommends taking medication for blood pressure that is well-managed by exercise and diet?
regular exercise + healthy diet / weight >> any medication you can take...
The point is that exercise can remove the underlying problem. And those who stay active enough don't develop it in the first place. Doc was amazed that I wasn't on any maintenance meds at 55. (Since then I've gone on blood pressure meds but if other health issues were resolved I don't think I would need them.)
Anybody can spike to 180 in a sufficiently stressful situation. (And, personally, I would very much notice 180. Otherwise calm, I'll probably notice 140.)
