What is considered low blood pressure?

Just a number. Well 120/80 has been considered average. Under 100 is getting low. But what is more important is how do you feel. If you feel well, i would not worry about a low blood pressure. Actually people with a low blood pressure live longer. I have seen patients with a pressure of 80/60 who feel quite well.
Depends on symptoms. This varies by age and symptoms. One important point is that a blood pressure that others consider normal /good (such as 110/70) could actually be too low in some medical conditions such as aortic stenosis. Generally, 90/60 would be a good official answer as the bottom limit, but this is normal in conditioned athletes and kids. Fatigue, dizziness, fainting are signs pressure may be too low.

What is considered low blood pressure and what would be considered high blood pressure?

Relative. Low blood pressure would, i suppose, be defined by most of us as a mean pressure < 50-60mmhg (big number + 2*small number / 3 is a rough estimate) but the clinical answer is that unless you're symptomatic (dizzy, lightheaded, passing out) almost any BP is ok. High is any systolic number that is usually > 140 or bottom usually > 90. Read more...

Varies with age/sex. Age, growth & gender alter the upper/lower levels considered normal for BP for kids. Systolic hypotension would be considered <60 for newborns<70 the 1st yr , <70+2xage up to 10 then <90 thereafter. Systolic hypertension is age, gender & length/height related in kids. Readings >~100-107 for 1-4yr progressing to 125-135 in late teens. Single values are less reliable than patterns. Read more...
