Just my two cents here -- Were you just borderline high? Did your doctor recheck your blood pressure a few times during the visit? Were you vaping right before you went in? On any cold meds, over the counter even?
I am on blood pressure medication and have been for over ten years. (I am 58 - only started vaping two months ago.) So many things influence your blood pressure, some only temporarily - salt, food, drink, cold meds, anxiety. You can remove some of the things that raise your blood pressure by watching your diet and learning to relax yourself as well as avoiding medications that many of us take not realizing that a side effect is the raising of your blood pressure. Many of us just inherit high blood pressure, or it becomes more of a problem if we are sedentary and put on a little weight or go through menopause. Millions of Americans have high blood pressure and have never vaped in their lives. It's so very common among us baby boomers, not sure how old you are, though.
Again, I am NOT a doctor, this is just my personal experience! My blood pressure fluctuates a lot based on what is going on at the moment. Being at the doctor's office, for me, is a guarantee it will be elevated. I hate checkups and only go when I have to! If I could lose 20 pounds, relax, and control my diet better I probably would not need blood pressure meds at all - but I live in the real world and I know myself. I'm still trying to lose the "baby weight" and my kids are in their 30s!
Good luck to you!
