'''Lightheadedness''' is a common and typically unpleasant sensation of dizziness or a feeling that one may faint. The sensation of lightheadedness can be short-lived, prolonged, or, rarely, recurring. In addition to dizziness, the individual may feel as though his or her head is weightless. The individual may also feel as though the room is "spinning" or moving. Lightheadedness often occurs when an individual quickly stands up. This is known as orthostatic hypotension. | '''Lightheadedness''' is a common and typically unpleasant sensation of dizziness or a feeling that one may faint.
