Diabetic Ketoacidosis Unusual Presentation of Latent Autoimmune Diabetes of Adult (LADA)

Latent Autoimmune Diabetes of Adult (LADA) is an autoimmune form of diabetes mellitus characterised by onset in adulthood and slow progression of beta cell failure. It is commonly misdiagnosed as type 2 diabetes mellitus and treated with oral hypoglycaemic agents, ultimately resulting in delay of insulin initiation. Acute hyperglycaemic crisis in the form of diabetic ketoacidosis is a rare initial presentation of LADA with very few cases reported so far. We present the case of a 40 year old housewife with no past or family history of diabetes that presented with diabetic ketoacidosis and was subsequently discovered to be affected with LADA.
