It took me until my early 40s to get up to that range. Genetics can play a role, no doubt. I had a grandmother who had potassium control problems that killed two of her brothers with heart attacks before they figured it out.
Lisinopril was one of the better meds my doctor tried on me before I fixed the problem myself.
Have you ever tried breathing exercises? Before the intermittent fasting fixed the problem, I found that slowing my breathing rate down was great for temporary BP reductions. Some people claim teaching your body to do it all the time can work on a permanent basis.
I’ve tried the intermittent fasting and can go a good while but about half the time I get a sick headache. I avoid caffeine so it’s not a caffeine headache. My Mom does the same thing with headaches.
I can do the breathing thing and when in a quiet place get it down to a very slow level. Getting time and quiet is the tricky part for me lol!
