I’m not a doctor.
You can drop dead from it. At minimum faint. And then if you hit your head or crash your car when you faint you can hurt yourself or others. But, you said you aren’t dizzy or spacey from it, so that is probably very unlikely. It can cause organ damage if not enough blood is getting to organs, like heart, brain, kidney. But, again probably unlikely for you, since you are not having symptoms.
Are those blood pressure readings first thing in the morning? Are you laying down? Are you a small petite person? A large tall person? Some people have those pressures as their normal, mine is easily those numbers in the morning. During the day I am up at 120/70 more or less. Why not talk to your doctor about adjusting your meds a little? I’m not a doctor, and I don’t personally have blood pressure problems (accept when my thyroid is out of whack, but I treat it with my thyroid medication not blood pressure medication) so I don’t know if blood pressure meds come in small increments where you can change the dose just a small amount?
Dr. Mercola was just on Dr. Oz a few weeks ago warning against low blood pressure induced by high blood pressure treatments. Dr. Oz was more focused and concerned about high blood pressure during the segment. Mercola was concerned about high blood pressure too, he just prefers life changes rather than meds, and warned against patients being overmedicated. Many doctors are not fond of Dr. Mercola, I like the guy because he does not just go only with the umbrella of belief, he is more analytical in my opinion, and he gets annoyed with the medical establishment. From the link it seems clear that low blood pressure concerns also have to be considered in concert with your other health problems you might have.
