It is said that normal blood pressuse is less than 120/80.
But I don't think the lower the better. My question is: how
low is too low? Thanks.

It's too low if your organs are not adequately perfused to
function properly.

Which organs???

Take your pick.

Yeah, that was a helpful answer.

In my relative's case, too low means you begin sweating
profusely, heart rate begins to race, you feel sick to
your stomach, light headed and if you don't lay down, you
will pass out.

Well, even as a layman I'm pretty sure that 0/0 will kill
ya.

Well, what more is to be said? Any organ inadequately
perfused will cease to function properly. Some organs are
more sensitive than others, with the brain being the most
sensitive.

Yes, this is the classic example. The brain is being
inadequately perfused so it stops functioning properly
(ie, you lose consciousness). The racing heart is your
body trying to increase blood flow to counteract the
low pressure.

If you're conscious and not constantly lightheaded, your
blood pressure isn't "too low." A bit of transient
lightheadedness when abruptly changing positions (e.g.,
sitting to standing) is not all that unusual, and not
worrisome. A BP of 120/80 would likely be considered
"normal" for most anyone. In *general* terms, a systolic BP
of less than 100mmHg is more likely to cause orthostatic (position-
related) symptoms, and in *general*, we would prefer to
maintain one's systolic BP above 100 to prevent this. There
is no absolute "too low" value, however. Hypertension is a
major cardiovascular disease risk factor, and is vastly
undertreated.

If you have a BP of -- let´s say -- 90/50 or so and
experience feel no symptoms, even that low blood pressure
can´t be considered too low in that particular case. In the
case you feel symptoms such as lightlessness, consult your
primary health care provider.
