Dr. Jaiwant Rangi explains how up to 40% of adult-onset type 1 diabetes and LADA cases are misdiagnosed as type 2, delaying insulin treatment. This mistake closes the window to preserve remaining beta-cell function. Earlier insulin therapy could prevent deterioration and reduce long-term health costs.

Dorothy is not rare. A large share of adults who actually have either type 1 diabetes or they have LADA are first diagnosed as type 2 diabetes, and some estimates put it near 40%. That's a big number. The tragedy is the lost time, the window where you can still protect what is left of the beta cell function that it was making. So I may have chosen to start insulin sooner in her case than to continue to put— continue with the pills. Every year you spend on the wrong plan, it's progressing further.
