| The tests are pretty conclusive and hard to falsely interprut.
But lets go worst case scenario-
The doctor thinks you have diabetes, so he tells you to diet and exercise. No harm there.
Or he starts you on oral meds. Oral meds really won't do anything if you don't have diabetes.
Or say he does think you need insulin. You'd be started on a small dose. Your healthy defense mechanisms (since you don't have diabetes) would prevent you from dropping very low.
Or say you did drop low. You would deal with the hypoglycemia just like any other diabetic would. Then you would keep dropping, and they would keep lowering your dose, till they realized their error of putting you on it. |
