What Is LADA?

LADA stands for latent autoimmune diabetes in adults. It is diabetes caused by your immune system slowly damaging the cells in your pancreas that make insulin.

Insulin is the hormone that lets glucose move out of your blood and into your cells, where it is used for energy. It is made by beta cells in the pancreas. In LADA, your immune system mistakenly treats those beta cells as a threat and destroys them over time.

That is the same underlying process as Type 1 diabetes. The difference is speed. In a child with Type 1, beta cells can be lost over a few weeks, and insulin is needed immediately. In LADA the loss happens over months to years, so when you are first diagnosed you still make enough insulin to manage without injections.

This is why LADA is so often recorded as Type 2 diabetes. You are an adult, you are not in a crisis, and tablets bring your numbers down. Everything fits the usual picture — until, months or years later, the tablets stop being enough.

LADA is not currently classified as a separate type of diabetes. Most specialists treat it as a slow-developing form of Type 1 that happens to begin in adult life.

It is not rare. In a European study of 6,156 adults aged 30 to 70 diagnosed within the previous five years, 9.7% carried the immune markers of autoimmune diabetes.

The way it is confirmed is a blood test for antibodies, not a judgement based on your age or build.
