In this episode of *Overheard in the Emergency Room*, Dr. Adrian Cois breaks down one of the most misunderstood medical conditions in modern healthcare: obesity.
Starting with a real case from the Emergency Department, we explore why obesity is not a failure of willpower but a chronic, biologically regulated disease. Drawing from major clinical guidelines and landmark studies, this episode walksthrough the science of weight regulation, the role of hormones like leptin and ghrelin, and why the body actively resists weight loss.
You’ll also learn about the two‑tier framework for obesity treatment:
Tier 1 – Foundational lifestyle interventions including nutrition, exercise, sleep, stress management, and multidisciplinary care.
Tier 2 – Evidence‑based medical treatments such as GLP‑1 medications like semaglutide and tirzepatide, as well as bariatric surgery.
We examine the data from major randomized controlled trials including STEP‑1 and SURMOUNT‑1, discuss long‑term outcomes from bariatric surgery studies, and tackle an often overlooked issue: weight stigma in healthcare.
Finally, we break down common myths promoted by wellness influencers and show how to spot misinformation when it comes to weight loss.

If you want to understand the real science of obesity — and what evidence‑based treatment actually looks like — this episode is for you.
