Back in high school I had high blood pressure, 135/90-95 range. I went on a serious low carb diet and slimmed down to 150 lbs 5 10”. Kept it off about 20 years and for 3 years didn’t salt anything. My blood pressure stayed high unless I took medication. It’s genetic as my Dad is trim and diet conscious and still has high blood pressure. I have two brothers who deal with it and another brother and sister who have never had an issue.
Currently I’m on lisinopril and a half a fluid pill daily and it’s been stable at 120/76 range regardless of diet for nearly fifteen years. I take the lisinopril before bedtime and fluid pill each morning.
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.
