I wish I knew! I'm a white female who was diagnosed in my late 20s. I've never been close to overweight, a vegetarian, I exercise, I quit smoking 8 years ago. I used to drink, but I quit even that over a year ago now. I had it under good control for a while, but my latest readings, on medication, are 170/100. :(
have you been screened fully for secondary causes (kidney problems, tumors, etc.)?
I see your post was in jan, i'd love an update if you're still around!
