I have very much enjoyed my time on Medhelp and have learned from you even while hosting our Ask-A-Doctor forum for Diabetes. Sadly I am leaving the Medhelp community as my own practice has become busier and time constraints have proved quite challenging. So from April 7th 2008 I will be officially away from Medhelp, but you can still find me at our practice website www.endocrinehelp.com, so please drop me a line if you wish. Most likely a new physician will be hosting the Diabetes forum for Medhelp in the future, so please continue to check in with the Medhelp community.
All the best to you and blessings for the future,
A second opinion is always reasonable.
The overnight dexamethasone suppression test is reassuring to decrease the possibility of cortisol-producing adrenal tumors, a pituitary tumor that produces ACTH, or a tumor in the body that inappropriately produces ACTH. A high-dose overnight test can additionally help distinguish a pituitary cause (Cushing's Disease) from the others.
