I am a 69 year old white male , non smoker in excellent health. I have moderate hypertension for 20 years controlled by moderate meds. Body weight is 175 lbs, height 5 9 and exercise daily, BMI is 24.5 Blood test ordered due to unknown reason for jump in blood pressure. All test results were normal and have been for 25+ years with exception of normetanephrine plasma which I had for the first time & was slightly high at 161, range is 0 - 145. Metanephines Plasma result also first time conducted was normal. I have a healthy diet, low cholestrol a moderate drinker, 1 bourbon (2 oz) before dinner. What do you think is causing the jump in blood pressure to 160 to 175 over 78 and what could be wrong?
