In this episode of Doctors Making a Difference, Dr. Peter Crane interviews Dr. Alexa Roth, a bariatric surgeon and obesity medicine specialist running a Center of Excellence program in Idaho. Dr. Roth discusses her path from competitive athlete and reluctant surgery student to falling in love with bariatric surgery, the psychological aspects of weight management, and how to approach patients with empathy and evidence-based options. They explore the strengths and limitations of lifestyle changes, GLP-1 medications, and surgical interventions, cost comparisons, insurance challenges, medical tourism risks, and early intervention in pediatric obesity. Dr. Roth also shares insights on public education through social media and her website. Episode Highlights From competitive athlete and internal medicine leanings to discovering a passion for surgery during a long Nissen redo case Why bariatric surgery offers uniquely rewarding long-term patient relationships and near-100% satisfaction The combination of technical laparoscopic skill, psychology/psychiatry overlap, and life-changing outcomes that drew her to the field Patient-centered approach: Meeting patients where they are, understanding their story, and avoiding shame/blame messaging Spectrum of treatments, lifestyle (5-7% TBWL), medications (up to ~22%), and surgery (20-40%+ TBWL), and how to match them to patient goals GLP-1 revolution making obesity more approachable and increasing patient willingness to seek care Cost comparison: Bariatric surgery often pays for itself in under a year vs. ongoing brand GLP-1 costs; long-term savings for the healthcare system Risks of medical tourism (lack of follow-up, complications, nutritional issues) and the importance of comprehensive lifelong support Early intervention in children and adolescents; family-wide benefits when adults pursue treatment Using authentic, short-form social media content to combat misinformation and educate the public Top 3 Takeaways Obesity is a chronic disease driven by genetics, epigenetics, and environment. Treat it with the same nuance and tools (lifestyle + meds + surgery) as diabetes or hypertension, not just “eat less and move more.” The best treatment is the one the patient will actually stick with; shared decision-making using realistic expectations on efficacy, cost, and lifelong commitment leads to better adherence. Surgery and medications are complementary tools, not competitors. Comprehensive programs that offer all options deliver superior, sustainable results and change entire families.
