A diagnosis of unstable blood pressure can be caused by a multitude of factors, illnesses and disease processes. Unstable blood pressure can provoke a variety of symptoms, including but not limited to dizziness, shortness of breath, instability, fainting and erratic heart rhythms.
A sudden fall in blood pressure also can be dangerous. A change of just 20 mm Hg â a drop from 110 systolic to 90 mm Hg systolic, for example â can cause dizziness and fainting when the brain fails to receive an adequate supply of blood.
