180. The Realities of Bariatric Surgery: Risks, Benefits, and Options with Dr. Laz Klein

Bariatric surgery is one of the most effective tools we have in obesity medicine—and also one of the most misunderstood.

In this episode, I’m diving into where surgery truly fits in the treatment of obesity and metabolic health. While we often focus on medical therapies like GLP-1s, it’s important to understand the role bariatric surgery can play—and why it continues to be underutilized or dismissed by many patients.

I’m joined by Toronto-based bariatric surgeon Dr. Lazar Klein, who shares his expertise on what bariatric surgery actually involves, who it’s for, and how it fits into a comprehensive, long-term approach to care. We walk through the most common procedures available — including gastric bypass, sleeve gastrectomy, and duodenal switch variations — and clarify why older procedures like gastric banding are no longer recommended.

Dr. Klein addresses common fears around surgery, including concerns about surgical complications, dumping syndrome and lifelong changes, while offering a realistic and balanced perspective on risk.

We explore the long-term outcomes as well—how surgery impacts conditions like type 2 diabetes, sleep apnea, and cancer and even mortality, and what the evidence shows about weight maintenance years down the road.

If bariatric surgery has ever felt confusing, intimidating, or “not for you,” this episode will help bring clarity to the conversation.
