HI...was she checked for hormone levels...the reason I ask is u said once she was pregnant it stopped for a while and the body adjusts and creates diff levels of hormones while pregnant.....so it may be she is lacking something while not pregnant??
Just a thought
Good Luck

Where did your wife go for the tilt table test? How close are you to Vanderbilt U. Med. Center? They have an Autonomic Dysfunction Center there. They would be your nearest, and probably best bet for correct treatment of NCS, if that's truly what it is.
If you repost this in the Dysautonomia forum, someone there they be able to give you more specific info for this condition.
