Why one size doesn't fit all—type 2 diabetes can operate differently across weight profiles

Research published in Diabetologia by Amsterdam UMC and the University of Ghana reveals that type 2 diabetes manifests in two fundamentally different ways depending on a patient's body mass index (BMI). While type 2 diabetes in patients with a higher BMI is primarily driven by insulin resistance, the study demonstrates that in individuals within a lower BMI range, the condition is caused by the pancreas failing to produce sufficient insulin. Despite these opposing biological mechanisms, medical professionals currently treat both groups with the same medications.
