I agree that high BP is not weight-related completely! It tends to be hereditary! My mother has always been teeny-tiny and she has very high BP! I have had high BP since in my early 20's too. I just now, at age 45, decided to buy my own cuff and I am checking it several times per day. I do take Lotensin for mine and it helps greatly with no side effects! Take care and keep the weight off because that DOES affect your health in many ways! I wish I could get myself in gear and drop some weight like you have!
