Nausea
Low blood pressure usually is most severe in the event that blood flow to critical organs has been reduced prolonged. In just minutes, the heart or brain may suffer irreversible damage from a decreased blood supply. Chronically low blood pressure (or even borderline low) can also be adverse for the kidneys. If the drop is sudden and severe, a sense of “imminent damage “is often described by patients. Rarely can syncope, shock, coma and even death result from a dramatic drop of weakness. If you lose consciousness and fall, even a relatively mild drop in blood pressure while standing can become dangerous, which is known as orthostatic hypotension.
