Re: found out could be diabetic
Not sure what this means because you didn't give a specific about the urine test. I'm wondering if it was for ketones? If you're spilling ketones, it would definitely have been dangerous for you to have a GTT, as the combination of high ketones and high blood sugar could, indeed, throw you into diabetic ketoacidosis (diabetic coma).
From all the symptoms you're describing, and assuming the 1,000 was ketones, then I would guess that you are probably diabetic and, quite possibly, Type 1. The next tests that should be done are an HbA1c, which will show your average blood glucose over the past 8-12 weeks...this catches every second of that time period, as opposed to random blood sticks which only capture one moment in time. It's possible that your fasting bg isn't all that high just yet (111 would be in the pre-diabetic range), but the fasting numbers are often the last to go. The other two test that should be done would be a C-peptide test and a GAD antibody test. These will show how much insulin you're producing (even T1's can produce some insulin in the honeymoon phase), and whether or not you're positive for GAD antibodies, which are only present in T1.
Of course, it's possible you're a Type 2, but either way, if you're diabetic, it needs to be treated...and determining which type you may be will help determine how to treat it.
Since your gynecologist sound pretty on top of things, I would just ask her to do the tests to determine what's going on. If you do turn out to have diabetes, I'd definitely ask her for a referral to a good endocrinologist, as they are the doctors who specialize in treating diabetes.
As scary as this may be, try to keep in mind that once you get a diagnosis and proper treatment, you will start feeling a whole heck of a lot better. Also, nowadays diabetes can be managed very well and complications can definitely be avoided by good management.
