Hi, I m on medication for moderate HBP. I started a low carb diet, eating lots of veggies and nuts and virtually no sugar. I ve seen my blood pressure decline to about 120/85, down about 10% on both measures. However, since I ve been tracking my blood pressure regularly, I ve noticed that when my heart rate is high (80 bpm vs 60 normal) right after exercise, my blood pressure is usually much lower (105/70, roughly). Is this normal?
