Hi doctors. i blood pressure medications, losartan 100 mg & metoprolol er 100 mg. at the nephrologist my blood pressure was 120/70. at the cardiologist a week later it was 145/80. i often get variable numbers. is this variability in readings normal?

Fluctuation of the blood pressure is common. Anxiety, apprehension etc could have made your blood pressure go up. Current recommendation recommends that the BP be recorded after several minutes of rest, with the patient seated and not engaging in conversation. In addition, depending on the timing of the BP with respect to taking the medications may also explain the difference.

Yes, variability in BP is common and differences between blood pressure machines and technique itself, specifically allowing for time for the blood pressure to settle are involved among others. Only 1 doc should make changes on your blood pressure meds, ideally your nephrologist or your primary care doc.
