Q: I have read several articles that say keeping BP below 120/80 is best. Sometimes my BP is below 120/80 but other times it is 138/78. I am an active individual so is keeping it below 120/80 practical?
A: Blood pressure is not constant throughout the day. A commonly accepted upper limit for ambulatory blood pressure is 135/85. You should discuss your blood pressure reading with your doctor. In situations where it is not clear if hypertension exists, 24 hour ambulatory blood pressure monitoring is a consideration.
