What is Hypotension?

Hypotension is abnormally low blood pressure (below 90/60). There are several different types of hypotension, depending on when blood pressure drops. These include:

  • Orthostatic hypotension: a sudden drop in blood pressure when standing up. 
  • Postprandial hypotension: a drop in blood pressure 1-2 hours after eating. 
  • Neurally mediated hypotension: a blood pressure drop after standing for a long period of time.
