The natural history of type 1 diabetes and LADA. Type 1 diabetes can be divided into six stages. LADA has a similar natural course to type 1 diabetes as its autoimmune subtype. However, the rate of decline of pancreatic β-cell function is lower than that of type 1 diabetes. Moreover, the natural history of most LADA patients can be divided into insulin-independent and insulin-dependent periods according to the degree of pancreatic β-cell destruction. There is great heterogeneity in the progression to insulin dependence in patients with LADA, which is associated with the age of onset, body mass index, genetic background, and immune, lifestyle, and environmental factors.
