IBS & Digestive Disorders

IBS is a description, not a diagnosis. Dr. Seubert's approach is to identify the underlying drivers — SIBO, dysbiosis, food intolerances, motility dysfunction, bile acid issues, or stress physiology — that conventional workups often label as "functional" and leave untreated.

Clinical Approach
  • ◆Comprehensive GI stool analysis and breath testing
  • ◆Targeted gut microbiome rebalancing
  • ◆Identifying true food intolerances vs. transient sensitivities
  • ◆Gut-brain axis support (vagal tone, HPA-axis stabilization)
Common Signs & Symptoms
  • ◆Chronic bloating
  • ◆Cramping linked to meals
  • ◆Urgency and unpredictable bowels
  • ◆Reflux
Questions

About IBS & Digestive Disorders

I've already had a colonoscopy with normal results — can you still help?+

Yes — this is the most common situation. A normal colonoscopy rules out structural disease but does not address functional GI causes, which is where naturopathic care is designed to work.

Ready to get to the root of it?
