How Low Can You Go?

Low blood pressure is good -- to a point

(HealthDayNews) -- You've no doubt heard about the dangers of high blood pressure. So, the lower your blood pressure goes, the better, right?

That's true, up to a point. As a general rule, the American Heart Association says any reading below 120/80 is good. Except if your pressure gets too low. That can lead to feeling lightheaded, fainting and even heart attack.

If you do have extremely low blood pressure, your physician should investigate the reason. Common causes for the problem are certain medications, illnesses or shock.
