Hi @ladybugmg. Welcome to Mayo Clinic Connect where a large population of people interested in medical challenges share their personal information and experiences and help each of us find good questions to ask our doctors. As a long-time veteran of high blood pressure and its treatment, I found a lot of good information on the Mayo Clinic website. You too may find important answers on these web pages:

First is a good overview of hypertension and most of its variants: https://www.mayoclinic.org/diseases-conditions/high-blood-pressure/basics/definition/con-20019580.

More on your point, here is some information on contesting high blood pressure without medication: https://www.mayoclinic.org/diseases-conditions/high-blood-pressure/in-depth/high-blood-pressure/art-20046974.

My hypertension comes from a rare inherited kidney mutation and may not be of much direct application to you. We'd know better about that if you care to share a little more information on your situation. For example, what are the dosages of Atenolol and Lisinopril of which you are taking a half-pill each day? Also, what is the range of your diastolic pressure? Your age also may be critical, since current standards for somewhat older persons don't count 130-140 as hypertension worthy of treating with medication at all, but only (as you hope) with lifestyle choices.
