Has Your Gut’s Ecosystem Been Compromised?

Your Gut's Bacterial Universe Revealed

Hi Friends,

Have you ever felt like your gut was suddenly “off”—maybe after starting a new medication?

Did your digestion change after a course of antibiotics, a colonoscopy prep, or recovering from a stomach bug?

Have you noticed more bloating, reflux, constipation, or food sensitivities after what seemed like a routine treatment?

If so, you’re not alone—and it’s not just coincidence.

Your gut is a complex, interconnected system. Each part—from your mouth to your colon—has a unique environment designed to support healthy digestion, nutrient absorption, and immunity. But when one part is disrupted—whether by medications, infections, or procedures—it can create a domino effect that throws the entire system out of balance.

🎥 Watch my short video for a visual breakdown of this powerful concept.


🔍 The Problem: When the Gut’s Natural Order Is Disrupted

The Mouth
Your oral microbiome plays a vital role in initiating digestion and protecting your body from pathogens. But harsh, alcohol-based mouthwashes can wipe out beneficial microbes, weakening this first line of defense.

The Stomach
Stomach acid is essential for breaking down protein, absorbing nutrients, and killing harmful microbes. Yet common acid-blocking medications like proton pump inhibitors (PPIs) raise stomach pH, reducing this protection and increasing the risk of bacterial overgrowth in the small intestine.

The Small Intestine
Our small intestine’s job is to absorb nutrients from our food. But when stomach acid is low or gut motility is impaired, bacteria can accumulate where they don’t belong—leading to SIBO (Small Intestinal Bacterial Overgrowth) with symptoms like bloating, gas, IBS, food sensitivities, and bowel irregularities. 

The Colon
Your colon is home to trillions of beneficial bacteria. But antibiotics, colonoscopy prep, and even frequent colon cleanses can strip away healthy flora—leaving you vulnerable to dysbiosisfungal overgrowth, and chronic inflammation.

The Domino Effect
These disruptions rarely occur in isolation. One medication or procedure can start a chain reaction—leading to imbalance, inflammation, and symptoms that linger long after the initial cause.


✅ The Solution: Restore Balance at Every Level

✔️ Reacidify the Stomach
Low stomach acid is one of the most common—and overlooked—drivers of poor digestion and SIBO. If you’re noticing symptoms like bloating, burping or belching after meals, this could be a sign of low stomach acid.
👉 Consider trying Betaine and Pepsin to restore optimal pH and support healthy protein digestion. If you take it after a meal and have no burning, this means you need it.

✔️ Clear Bacterial Overgrowth in the Small Intestine
When bacterial imbalance occurs where it shouldn’t, herbal antimicrobials can target it without harming the good bacteria in your colon.
👉 My 4-phase SIBO protocol uses herbal antimicrobials to address overgrowth gently and effectively.

✔️ Rebuild the Colon Microbiome
After disruption from antibiotics or colonoscopy prep, it’s essential to repopulate the microbiome.
👉 I recommend Probiotic 225 Billiona high-potency, multi-strain blend that supports recolonization and diversity.

✔️ Support the Oral Microbiome
Skip the alcohol-based mouthwashes, which can wipe out good microbes.
👉 Try oil pulling with coconut oil to remove fat-soluble bacteria while preserving healthy oral flora.


💡 Final Thoughts

Gut healing isn’t about wiping out bacteria—it’s about restoring balance in each section of your GI tract. When we work with the body’s natural design—not against it—we can support better digestion, immune resilience, and long-term wellness.

🌿 A Note on Gut Healing

If you’ve recently taken antibiotics, gone through a colonoscopy prep, or just feel like your gut is out of balance, this is one of the most important times to support your microbiome.

That’s why, now through Sunday, May 25, I’m offering 15% off when you purchase 3 bottles of Probiotic 225 Billion—a high-potency formula I use with my patients to help restore healthy gut flora after disruption.
