A Comprehensive 4-Phase Naturopathic Approach

Small Intestinal Bacterial Overgrowth (SIBO) is one of the most common yet under-diagnosed causes of chronic bloating, gas, abdominal distention, and irregular bowel movements. Many of my virtual patients have spent years feeling uncomfortable after meals, only to discover that an overgrowth of bacteria in the small intestine was the hidden driver.

Unlike conventional approaches that focus only on killing bacteria, true SIBO recovery requires a thoughtful, phased protocol. In my virtual naturopathic practice, I guide patients through a structured 4-phase process designed to address root causes, restore balance, and prevent recurrence.

What is SIBO and Why Does It Happen?

SIBO occurs when bacteria that normally live in the large intestine migrate into the small intestine, where they ferment carbohydrates and produce excess gas. Common contributing factors include:

  • Impaired gut motility (often linked to nervous system dysregulation)

  • Low stomach acid

  • Previous infections or food poisoning

  • Structural issues or adhesions

  • Stress and vagus nerve dysfunction

  • Liver-Spleen imbalance in Traditional Chinese Medicine

  • Proper testing (SIBO breath test or comprehensive stool analysis) is essential before beginning any protocol.

The 4-Phase SIBO Recovery Approach

Phase 1: Build a Solid Foundation

Before attempting to “kill” anything, we strengthen the body’s natural defenses. This phase focuses on:

  • Supporting a robust gut immune system through nutrient-dense, real-food meals, and supplementation

  • Gentle detoxification support

  • Nervous system regulation to improve motility and vagal tone

  • Optimizing hydration — I personally use my Enagic K8 for hydrogen-rich structured water to support cellular health

This foundational phase typically lasts 2–4 weeks and helps reduce die-off reactions later. Many patients notice improved energy and less bloating even before the active antimicrobial phase.

Phase 2: Kill Phase – Balancing the Microbiome

Once the foundation is stronger, we address the bacterial overgrowth directly while protecting beneficial flora:

  • Targeted herbal antimicrobials (such as berberine, oregano oil, or neem) — chosen based on your specific test results

  • Continued real-food diet

This phase is highly individualized. Duration varies, but careful monitoring helps minimize side effects.

Phase 3: GI Repair Intensive

After reducing bacterial load, the focus shifts to healing the intestinal lining:

  • Key nutrients like quercetin, L-glutamine, zinc carnosine, and slippery elm

  • Demulcent herbs (marshmallow root, deglycyrrhizinated licorice/DGL)

  • Anti-inflammatory real foods

  • Acupuncture-inspired self-care points to support Stomach and Spleen Qi

This phase is crucial because damaged gut lining often leads to relapse if not properly addressed.

Phase 4: Maintenance – Repopulate, Prevent Recurrence & Continue Repair

Long-term success depends on preventing regrowth:

  • Gradual repopulation with diverse, high-quality probiotics and prebiotics

  • Prokinetics (motility agents) to support healthy migrating motor complex (MMC) function

  • Ongoing nervous system balancing practices

  • Lifestyle habits that support healthy motility (meal timing, movement, stress management)

  • Periodic re-testing when needed, if needed

  • Joyful, sustainable whole-food diet

This is where patients truly reclaim their freedom with food and daily comfort.

Is This Approach Right for You?

SIBO recovery is rarely one-size-fits-all. The most successful outcomes come from personalized guidance, proper testing, and professional support.

If you suspect SIBO or have been struggling with recurring digestive symptoms, I invite you to book a virtual discovery call.

Together we can determine the best path forward using root-cause testing and a compassionate, phased approach.

“Dr. Kryzia Olsen has been a refreshing cure. I've been sick for over a year thinking that my gluten issues had just gotten out of control. As I tracked what I ate and realized I was truly gluten free I figured something else had to be going on.

I got in to see her same day. Took a SIBO test that weekend and had a healing plan in place by the end of the next week. I feel better than I have in months. Dropped 10 pounds of bloat and am able to expand my food world.

Dr. Olsen is smart, fresh, understanding and no nonsense. She listens to me and how I learn and adapts the plan to fit me. A Doctor who listens instead of talking? She is a rare find and I appreciate her.”
