Which one is more dangerous, low or high?

I feel that high blood pressure is more dangerous than low, because high blood pressure can lead to various other dreadful diseases like myocardial infarction (heart attack), cerebrovascular accident (stroke), TIA, diabetes, stress, etc which can cause even deaths. Even though low blood pressure is also dangerous but comparitively I would say you should be worried more about high blood pressure than low.

Both are dangerous conditions but hypertension gets more press because more people have it. As we continue to live on unhealthy lifestyles and high on fat diets, hypertension will continue to rise. I'm not a doctor but I think hypertension is much more dangerous because hypotension is easier to treat and has less side effects.

both of them was dangerous. High is very dangerous

both are...pressure must be normal or moderate ..

Both r equally dangerous and risky.with low B.P.u can feel giddy and fall down. u can so injure yourself seriously if u r in an activity like driving a motorcycle or travelling on the footboard of a moving train/bus.With high B.P.u can get brain hemmorage,nose bleeding ,lead to diabetes etc.
