Standing for long periods
by Acadia, May 16, 2004 12:00AM
When I must stand for more than 20 minutes or so, I become nauseated and soon start to black out. The problem is relieved by sitting but returns when I stand again for a short while. It happens regardless of the activity that requires me to stand. For example, doing dishes is particularly hard because not only am I standing, but I am working with my arms extended. I sit whenever possible while cooking, such as when chopping. This has gone on for years.
I need to solve this problem, because I sing in a professional choir and it is disruptive for me to sit during performances when the rest of the choir is standing, and I may be asked to resign. This doesn't seem to be a problem for other singers.
I don't know even what area of medicine might address this problem. Is circulation the issue, and does it have a solution? I have very lttle endurance. It does not vary with weight, which has generally been normal. My heart rhythms are fine. I have been on Synthroid for 20 years, and my thyroid function tests are normal. I have a diagnosis of Chronic Fatigue Syndrome, but it doesn't help me solve this rather urgent performance problem. Any suggestions? I need help!

One consideration would be orthostatic hypotension. Causes for this are many, but one consideration would be chronic autonomic failure. This usually leads to a drop in blood pressure when standing, leading to the symptoms you describe.
Tilt-table testing is normally the test to evaluate this. Tilt table testing typically reproduces the clinical symptoms in association with a heart rate increase 30 beats/min or a maximum heart rate 120 beats/min within the first 10 minutes.
If this is the case, there are medications used to treat this - including mineralcorticoids as well as alpha-1 adrenergic agonists. You may want to discuss these options with your personal physician.
Followup with your personal physician is essential.
