i'm not sure what you mean by hypertension or what method you are using to determine you have it. however untreated high blood pressure is a dangerous disease with consequences that can reduce your quality of life cause serious chronic disease or kill you. it has been implicated in altzheimer's disease as well. if you are not diagnosed you will not be able to receive treatment. you are very young and deserve to have a beautiful life--don't risk it by not taking care of yourself.
if i have my undiagnosed hypertension diagnosed it will become a preexisting condition. why should i have it diagnosed? . in late 20s always around 160-170 lbs at 5'11. semi-active. havent had a checkup in over 10 years. hypertension has lessened some of what i could do but otherwise i've lived with it just fine. plus i have other medical issues that are more intrusive to my quality of life which will never go away. if i have hypertension diagnosed then it will become a preexisting condition and will cost me 10s if not 100s of thousands of dollars in added medical costs during my life.
