Up to a third of people who were initially diagnosed as having Type 2 Diabetes (T2D) actually have latent autoimmune diabetes of adults (LADA), sometimes refer to as Type 1.5 Diabetes. People with LADA have features of both Type 1 Diabetes (T1D) and T2D – their immune system attacks the cells of the pancreas that produce insulin, but they may also develop insulin resistance. The destruction of the insulin producing cells is much slower in LADA than in T1D. A blood test is needed to tell the difference between T2D and LADA. Some people can manage LADA on diet, exercise and tablets in the initial months or years following diagnosis. However, most will move onto insulin therapy at some point.
