A member asked:
I have noticed that i seem to get light headed and kind of black out for usually about 5 or so seconds after standing up from a sitting down position?

RESPONSE: Sounds consistent with a postural blood pressure drop, which could be due to many causes, including dehydration, anemia, thyroid issues, medication, recreational drugs, etc. Have your doctor check your blood pressure supine and standing, and do testing to uncover causation.
