Hypertension/Hyperthyroidism?

I'm 21 yrs old and am 5ft3in and 100lbs. I can't gain weight at all and I believe I have a high blood pressure. Was wondering if my hyperthyroidism has something to do with my high bp? I eat regularly(my diet may not be the healthiest though), my heart pulse elevates most of the time, no drugs taken. Should I consult my doctor to see if I need meds or is this normal?
