With blood sugar tests that were within normal limits and the polyuria evanescent, I don’t think that your small son shows any evidence of prediabetes. Anyway, his chances of ever becoming insulin dependant are only about 5%. At the same time, I understand your concern so perhaps a negative antibody test would be a reassurance. I rather doubt though that this test would be available through the army medical services, but you could ask.
Unfortunately, even if the test were positive, there is no way at the present for delaying the need for insulin. Unhappily two big studies, one in Europe called ENDIT (using nicotinamide ), and another in the U.S. and Canada called DPT-1, (using very small doses of subcutaneous insulin) were both recently shown to be unsuccessful. Despite these disappointments, active research is continuing both on preventing type 1A (autoimmune) diabetes and on maintaining insulin production and even regenerating it.
