My 15 year old son has 198/115 blood pressure, he is 5'9 and 140 lbs. Could this be hereditary? My son was diagnosed with high blood pressure. His dad had high blood pressure and his grandfather died of a stroke at 33. His blood pressure was 198/115. His doctor put him on lisconipren. Is this drug harmful? Did he get this from his dad or grandfather? He eats good and exercises regularly.
