This 30‑minute lunchtime webinar will explore emerging evidence on hypercortisolism in patients with difficult‑to‑control diabetes, with a focus on implications for screening, diagnosis, and management. Prompted by recent large‑scale “CATALYST” study findings suggesting a potentially higher-than-expected prevalence of hypercortisolism in this population, the session will critically review the underlying evidence, including diagnostic criteria, limitations, and ongoing controversy.
