Hi there
@AnnieWales , my brother has LADA. LADA stands for Latent Autoimmune Diabetes in Adults. It is sub category of Type 1 diabetes. Type 1 diabetes is an autoimmune disorder whereby the body's own immune system attacks the islet and beta cells of the pancreas, causing total failure in insulin production resulting in diabetes. T1 individuals must go on insulin therapy for the rest of their lives.
T1 in children, in general, happens very quickly once the autoimmune response is triggered, sometimes within days. In LADA however, the autoimmune response is slower. It can often mimic type 2 diabetes in the initial stages. My brother for instance, was prediabetic for a number of years. His blood sugars increased and he became diabetic. He was put on Metformin. He was able to stay in the prediabetic range on Metformin for a number of years until his blood sugars started to rise. He started to lose weight. His blood sugars became very high, in the 40's. He was tested for T1 diabetes and it was confirmed he had T1 (LADA).
With LADA the rate at which the autoimmune response varies in speed from individual to individual. It can happen in less than a year or it can take many years, but the outcome is always the same, total destruction of the islet and beta cells. It is not reversible.
AnnieWales I hope that explains LADA for you.
