Age 53, normal bp 120/80, for last few hours bp is 165/110?

Elevated BP: Although, the #s you quoted are higher than normal, we don't know what circumstances those were measured in. If you felt stressed, anxious, had a smoke or were after exercise, this may not be unusual for your blood pressure to go up. Perfect conditions to measure your blood pressure in would be after 10-15 minute rest, sitting with the cuff at the heart level. Do it first thing in A.M.
