LADA is basically a slow-onset Type 1 in adults. (Latent Auto-immune Diabetes in Adulthood) Often misdiagnosed in early stages as T2 especially if you present as the classic middle-aged, obese, non-exercising kind of person I did who then spent two years protesting I was doing absolutely nothing to lose weight the way I was doing (Mind you, some of it has come back again and lockdown is not helping that one) and nor was I lying or cheating about my food/exercise as everything began spiraling out of control despite strict low carb, loads of walking, and ever-increasing oral meds.
There are other types of diabetes as well, but I won't add to the confusion.
