Something might show up but they might decide not to tell you. Type 2 is generally a progressive disease and the rate of progression can vary dramatically. The point where "diabetes" is actually diagnosed is somewhat academic, "prediabetes" where your numbers are no longer normal but haven't reached the diagnostic threshold yet may continue for years during which damage is occurring. Because they think this progression is inevitable some doctors won't bother telling you - but actually you can slow down or stop the process through diet and exercise if you catch it early enough.
