CLASS OVERVIEW
The systematic approach to complex GI cases that conventional medicine misses
How many times have you found yourself working with a new patient trapped in the no-win game of symptom management? As functional medicine practitioners, helping people find relief when conventional medicine falls short is our bread and butter, yet even we can fall back into surface-level treatment protocols without the right framework.
Dr. Steven Sandberg-Lewis has spent over 45 years developing a unique clinical approach that views illness through the lens of adaptive strategy. What if your patients' symptoms are actually their bodies' best attempt at getting well again? This perspective sheds light on otherwise complex cases and helps you avoid dropping anchor on diagnosising prematurely.
In this comprehensive presentation, Dr. Sandberg-Lewis shares his step-by-step, practical approach to decoding complex digestive patients, from data collection to lab interpretation and clinical "pearls of wisdom" that can help your most challenging patients find lasting relief.

The Misdiagnosed GI Cases Hiding in Your Practice
Your most challenging GI patients have often seen 5+ practitioners before reaching you. They've been tested repeatedly, diagnosed with SIBO or IBS, and cycled through multiple treatment protocols, yet nothing delivers lasting results. The real tragedy? Their suffering often isn't due to treatment-resistant conditions, but instead underlying mechanisms not yet identified, such as:
Meanwhile, "diagnosis momentum," blindly trusting previous practitioners' conclusions without examining raw lab data, leads you down ineffective treatment paths.
The standard glucose breath test misses distal small intestine overgrowth. Negative celiac tests are accepted as accurate when improper testing protocols render them meaningless. Patient preparation for labs is overlooked, guaranteeing false results that derail your entire approach.
These aren't rare edge cases. These are systematic blind spots affecting your most complex patients right now. While you're playing diagnostic "whack-a-mole" with downstream symptoms, the true drivers of dysfunction remain unidentified and untreated.
- Hypermobility syndrome that goes unscreened despite driving, chronic gastritis, and constipation.
- Traumatic brain injuries from decades ago continue wreaking havoc on gut motility.
- Exocrine pancreatic insufficiency that sabotages recovery.

Did You Know...
Did You Know...
Hypermobility is associated with increased risk of chronic gastritis, constipation, GERD, and celiac disease.
The simple Beighton score can screen for hypermobility syndrome during a standard office visit.
Many negative celiac test results are inaccurate due to improper testing protocols and interpretation.
The standard glucose breath test for SIBO may miss distal small intestine overgrowth entirely.
Exocrine pancreatic insufficiency (EPI) is commonly seen in patients with SIBO and hypochlorhydria, leading to the malabsorption of critical nutrients.
Even "mild" TBI can cause long-term GI effects, including gastroparesis, reduced nutrient absorption, leaky gut, and food intolerances.
Introducing the Master Class That Transforms How You Approach Complex GI Cases
Dr. Steven Sandberg-Lewis's comprehensive training delivers the gastroenterological expertise that's been missing from your functional medicine toolkit. With over 45 years of clinical experience, Dr. Sandberg-Lewis has developed a systematic methodology for identifying the underlying mechanisms that most practitioners miss.
This isn't theoretical knowledge; it's battle-tested clinical wisdom from decades of successfully treating challenging digestive cases. You'll learn to view illness as an adaptive strategy, spot critical connections that others miss (like hypermobility and TBI), and implement proven protocols that help your patients break through treatment plateaus.
While other practitioners play diagnostic "whack-a-mole" with symptoms, supplements, and diets, you'll learn how to create targeted treatment plans that deliver lasting results for complex GI patients.

2
Identify Underlying Mechanisms
Learn to screen for commonly overlooked factors like hypermobility syndrome, TBI, and exocrine pancreatic insufficiency.
3
Interpret Advanced Labs
Understand raw lab data, why negative celiac tests can be inaccurate, how to prepare patients for breath testing, and which markers reveal diagnostic insights.
