Type 1.5 diabetes, or latent autoimmune diabetes in adults (LADA), is a lesser-known form of diabetes that combines features of both type 1 and type 2 diabetes. While type 1 and type 2 are more widely recognized, the emergence of type 1.5 diabetes has come into the spotlight recently with Lance Bass revealing his diagnosis. So, what exactly is type 1.5 diabetes, and how does it differ from its more common counterparts?
Understanding Type 1.5 Diabetes
Type 1 diabetes is an autoimmune condition where the body attacks the pancreas cells responsible for producing insulin, leading to insulin deficiency. On the other hand, type 2 diabetes is characterized by insulin resistance and inadequate insulin production by the pancreas. Type 1.5 diabetes falls somewhere in between, with the immune system attacking pancreatic cells but at a slower pace than in type 1 diabetes. People with type 1.5 often do not require insulin immediately, unlike those with type 1, but eventually may need it within five years of diagnosis.
Type 1.5 diabetes is typically diagnosed in adults over 30 years old, making it distinct from the usual onset ages of type 1 and type 2 diabetes. The condition shares genetic and autoimmune risk factors with type 1 but can also be influenced by lifestyle factors like obesity and physical inactivity, commonly associated with type 2. Symptoms of type 1.5 diabetes vary but may include increased thirst, frequent urination, fatigue, blurred vision, and unintentional weight loss.
Initial treatment for type 1.5 diabetes often involves oral medications to regulate blood glucose levels. Regular monitoring of blood glucose levels is crucial, with a progression to insulin therapy if oral medications are inadequate. However, there is no standardized approach to managing type 1.5 diabetes, and treatment plans vary based on individual needs and responses to medication. Misdiagnosis of type 1.5 as type 2 diabetes is not uncommon, as identifying the condition requires specialized antibody tests that are not always routinely ordered.
There is limited research on the prevalence of type 1.5 diabetes, especially in non-European populations, which has hindered understanding and diagnosis of the condition. Misdiagnosing type 1.5 as type 2 diabetes can lead to delays in receiving appropriate treatment, potentially resulting in worsened health outcomes and increased risk of complications. Greater awareness and clearer diagnostic criteria are needed to ensure individuals with type 1.5 diabetes receive timely and effective care.
Type 1.5 diabetes represents a unique and often misunderstood form of diabetes that falls between type 1 and type 2 in terms of characteristics and progression. Awareness of this condition is essential to ensure accurate diagnosis and appropriate treatment for individuals with type 1.5 diabetes. By recognizing the distinct features of type 1.5 diabetes and the challenges associated with its diagnosis, we can better support those affected and improve outcomes in managing this lesser-known variant of diabetes.
