Ketosis Resistant Diabetes Mellitus is a term used to describe a rare form of diabetes that is difficult to manage. This type of diabetes is also referred to as ketosis-resistant diabetes, type 1.5 diabetes, or latent autoimmune diabetes in adults (LADA). LADA is characterized by a slow progression of symptoms, often mistaken for type 2 diabetes, but with an underlying autoimmune cause. This condition is resistant to traditional diabetes treatments, and patients may require insulin therapy earlier in the disease progression. Other synonyms for ketosis-resistant diabetes include slow-onset type 1 diabetes, late-onset autoimmune diabetes, and type 1.5 LADA. These alternative names help to better describe the nuances of the disease and may aid in diagnosis and treatment.
