I feel your pain I've got hypertension, overweight don't want to take medicine because it causes problems. Of course losing weight helps but what else has helped me is I use garlic supplements get the odorless kind. I also take a hawthorn supplement, watermelon is a diuretic if you can eat it frequently. Donate blood, u can do a google search on donating blood it forces you to make new blood so it don't get stagnant and thick. Keeps you from depositing plaque on your arteries. Good luck but I would do frequent checks and if you can't get it under control I would consider taking bp meds
over risk of having a floppy heart or stroke.
