From the information you gave in your post, I would not be too concerned by the pending approval of the Endo. (easier said then done... I know)
I think it is simply another layer of protection for the Endocrinologist as well as the patient. He gets to talk with you, see where you at health wise and what not. If there was to be any concerns on his part, he would share those with you, but from the sound of it, I don't think you will have much of a problem.
Sounds like you still have a little while to wait until you see him, so I would suggest continuing to take good care of yourself and ensuring that you find ways not to let it stress you out too much (again, much easier said then done).
