When is blood pressure too low and what can one do about it?

Obviously, if someone has lost a lot of blood after being injured, their blood pressure will be low, but in an otherwise healthy person, there seems to be no bottom cutoff point when it comes to measuring low blood pressure.

Doctors can test blood pressure when a person is lying down and after they have stood up to determine whether there is a significant difference.

Often low blood pressure is disease-based and the disease needs to be treated before the blood pressure will be corrected.

If someone is basically healthy, there is no way to bring up their blood pressure. Drugs claiming to do this can be unsafe.
