Im 18 and always seem to have high blood pressure, even reaching to the 180s and 160s at times. my doc never done anything about it? im kinda scared?

You should be!!!!: That is absurd! the probable cause is diet. More and more young people are unhealthy and the major cause is lousy diet. Get rid of caffeine (e.g.Energy drinks, coffee, tea, even green tea) and all forms of sugar. Difficult? Sure, but your health is in your hands, not the doctor's.

Ask your doctor : Sometimes although it should not happen a doctor can overlook a young person's blood pressure. Ask your doctor to look at your blood pressure trend over past several visits. Get your BP at the pharmacy when you are relaxed several times in a week and tell md what they bp's are. Diet and exercise and avoid caffiene. But you may need meds. Do u have a family history of high BP and tell md.
