Low Blood Pressure: The 10 Symptoms You Can't Afford to Ignore

5. Fainting

Fainting or passing out is also called syncope, an unexpected, momentary unconsciousness caused by lack of blood flow to the brain. This is often a sign of blood pressure problems and can happen quite often if you move too fast from a lying or sitting position to a standing position. Fainting from low blood pressure is most common in older adults. It also frequently occurs in people recovering from lengthy illnesses that kept them bedridden long enough to affect muscle tone.
