http://en.wikipedia.org/wiki/Hypotension
In physiology and medicine, hypotension is low blood pressure, especially in the arteries of the systemic circulation.Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood.
Hypotension is generally considered systolic blood pressure less than 90 millimeters of mercury (mm Hg) or diastolic less than 60 mm Hg. However, in practice, blood pressure is considered too low only if noticeable symptoms are present.
For some people who exercise and are in top physical condition, low blood pressure is a sign of good health and fitness.
For many people, excessively low blood pressure can cause dizziness and fainting( Especially in Old Age) or indicate serious heart, endocrine or neurological disorders. Severely low blood pressure can deprive the brain and other vital organs of oxygen and nutrients, leading to a life-threatening condition called shock.
