Why Adults Get Labelled Type 2

Almost everyone diagnosed with diabetes after 30 is recorded as Type 2. Understanding why makes it easier to ask for something different without feeling you are challenging your doctor.

The main reason is arithmetic. Type 2 accounts for the overwhelming majority of adult diabetes, so it is the sensible first assumption. A clinic seeing a hundred adults will be right about it most of the time.

The second reason is that on the day of diagnosis, LADA genuinely does look like Type 2. There is no crisis, no ketoacidosis, and tablets bring the numbers down. The features that would eventually distinguish it have not appeared yet.

The third is cost and availability. Antibody testing is not part of routine diabetes diagnosis anywhere, including in India, and adding it for every adult would be expensive.

There is a fourth reason that is easy to miss. Careful comparison of thousands of adults found that antibody-positive people were on average younger, leaner and slimmer around the waist — but that no clinical feature separated the groups cleanly enough to use as a filter. Doctors are not overlooking an obvious sign. There often is not one.

The consequence is delay, commonly several years. That is why it usually takes the patient noticing the pattern — control slipping despite rising doses — for the question to be asked at all.
