The relationship between orthostatic dizziness and hypotension in male medical students

We carried out a questionnaire survey regarding symptoms of orthostatic dysregulation (OD) and administered the Schellong test (orthostatic test) to 123 normal male medical students aged 21–29 years to investigate the relationship between orthostatic dizziness and hypotension. OD was identified in 15 (12.2%) of the subjects based on the questionnaire results. Orthostatic dizziness was noted in 40.7% of the subjects (50/123). The occurrence of orthostatic dizziness was most significantly related to systolic pressure decrease during the procedure for the Schellong test. These results suggest that the testing procedure introduced by Schellong can be useful, and clinically applicable to the assessment of orthostatic dizziness, since it presents the advantage of being simple enough to carry out in clinical practice.
