Although LADA is also an adult, it is not a “true” type 2 diabetes, but a type 1 diabetes, which is jokingly called type 1.5 diabetes because the clinical features are between type 1 diabetes and type 2 diabetes. LADA is usually defined as “diabetes mellitus diagnosed in people aged 30-50 years who do not initially require immediate insulin”. There are two clinical phases in the progression of adult occult immune diabetes: the non-insulin-dependent phase and the insulin-dependent phase. The treatment of LADA has two main aspects: first, lowering blood glucose; and second, protecting islet function. First; it includes basic diabetes self-management. Exercise, avoid refined plus grain-based foods; eat a healthy diet and check your blood sugar levels to find out what makes them go up and down. Secondly, LADA patients should avoid sulfonylureas. LADA patients with good metabolic status, including blood glucose, glycosylated hemoglobin and pancreatic islet function, can consider using other oral hypoglycemic treatment options besides sulfonylureas, for example, you can use biguanides, etc. There are also glycosidase inhibitors that can be applied in conjunction with them, all of which can be chosen, and progressing to the insulin-dependent stage will require consideration of starting Third, patients with LADA who have high titers of islet autoantibodies and poor metabolic status need to be treated with insulin early.
