I was diagnosed with malignant hypertension last year when it was 185/90 several times (discovered during an ER visit for bronchitis) - never had any BP problems before. Doctor told me to exercise, watch my diet and lose weight. I did all 3 but BP stayed high, usually 150-160/90 and a few times 185 again. January a new doctor put me on lisinipril 20mg/day. now BP is always below 130 (upper) and stays around 75/80 lower. Today at the fitness center I felt exhausted and staff took my BP, it was 80/60. staff made me sit, drink fluids, and stay until it got up to 98/70. they were very concerned. is low BP really a big deal? I know i can get stroke,etc for high, but other than fainting what is risk of low BP?
