My BP is about 130/90 and after running for 5kms, it usually drops to 110/70. The more I run, the more it drops. Is this normal? I take Norvasc 5mg 1x/day.
The medicine you take, Norvasc, works by relaxing your blood vessels. Consequently, it affects your body’s ability to respond to the increased oxygen demands of exercise. You should ask your doctor to recommend a heart rate for you during exercise. Heart rate is easy to monitor during exercise and a variety of monitors are available. Your question did not state when you are measuring your blood pressure – during, immediately after running, or several hours after running. It is difficult to give an opinion about your blood pressure response without this information. I am concerned that you may be training too hard.
