Understanding "Leaky Gut" (Intestinal Permeability)
If you're having symptoms of abdominal pain, heartburn, chronic bloating and gut distention that gets worse throughout the day, eczema and skin issues or IBS, "leaky gut" should be considered as a potential cause.
Your intestinal lining is designed to be selectively permeable, allowing beneficial nutrients to pass into your bloodstream while blocking harmful substances. When the tight junctions between intestinal cells become compromised, you develop intestinal permeability (a/k/a "leaky gut").
This condition allows larger molecules, bacterial fragments, and toxins to escape through the intestinal barrier and enter your bloodstream. Your immune system recognizes these as threats, triggering inflammation that can affect your entire body and contribute to a wide range of health challenges.
Why Choose Naturopathic Care for a "Leaky Gut"?
"Leaky Gut" isn't considered an official diagnosis in gastroenterology nor does it have a specific treatment. They may perform endoscopy or colonoscopy and not see much -- or recommend medications to address symptoms but not the cause. And this leaves a lot of suffering patients in a confusing, gray area.
However, we know "leaky gut" can occur from inflammation and we can test for it (Zonulin). Naturopathic medicine offers distinct advantages for GI patients who haven't found relief through conventional approaches:
Root Cause Focus: We don't just treat symptoms; we identify and address the underlying causes of your digestive dysfunction
Personalized Treatment: No two GI patients are identical. Your treatment plan is customized based on your unique biochemistry, test results and health goals
Comprehensive Testing: Access to advanced functional medicine tests not typically available through conventional gastroenterology, such as the Zonulin marker to identify a potential "leaky gut"
Natural Therapies: Emphasis on diet, lifestyle, and natural medicines before considering pharmaceuticals, with fewer side effects
Whole-Person Care: We address how stress, sleep, hormones, and other body systems impact your digestive health
Education & Empowerment: You'll understand what's happening in your body and why, with tools to maintain your digestive health long-term
What Causes a "Leaky Gut"?
Dietary Factors
Processed foods, inflammatory fats, excess sugar, food additives, emulsifiers and diets high in FODMAPs can compromise barrier integrity and promote inflammation.
Chronic Stress
Prolonged stress activates pathways that increase intestinal permeability by affecting tight junction proteins and promoting inflammatory responses throughout your gut.
Certain Medications
NSAIDs (like ibuprofen), antibiotics, and certain other medications can directly damage the intestinal lining or disrupt your protective gut microbiome.
Microbial Imbalance
Dysbiosis—an imbalance in your gut bacteria—can weaken the mucous layer, trigger inflammation and compromise the structural integrity of your intestinal barrier.
Alcohol & Toxins
Excessive alcohol consumption and environmental toxins can directly damage intestinal cells and increase permeability through multiple mechanisms.

Frequently Asked Questions about "Leaky Gut"
Is leaky gut actually real, or is it just alternative medicine hype?
Intestinal permeability is absolutely real and well-documented in medical research. It's measurable using validated tests and occurs in conditions like celiac disease, Crohn's disease, and IBS. What's controversial is whether it's a standalone syndrome or primarily a symptom of other conditions. I focus on evidence-based assessment and treatment of measurable barrier dysfunction, not unproven claims. If you have digestive symptoms, we investigate the actual cause rather than making assumptions.
How much does leaky gut testing and treatment typically cost?
Initial consultation with me costs $595 and the lactulose-mannitol permeability test costs approximately $150-250. Treatment costs vary based on your specific needs, but I prioritize affordable, evidence-based interventions over expensive supplement protocols. Many patients find that dietary changes and selective supplementation (often $50-250/month) provide significant benefit. I'll always discuss costs upfront and work within your budget.
Are the at-home leaky gut tests I see online reliable?
Quality varies dramatically. Personally, I don't like them. The lactulose-mannitol urine test is the most validated method when done through reputable labs, but interpretation requires clinical expertise. Many online tests measure biomarkers like Zonulin, which can indicate permeability but aren't definitive on their own. Stool tests alone cannot diagnose leaky gut. I use clinically-validated testing and interpret results in the context of your complete health picture, not as isolated data points. This prevents unnecessary treatment and ensures we're addressing actual problems.
My primary care doctor says leaky gut isn't real. Why the disconnect?
Many conventional physicians are rightfully skeptical of "leaky gut syndrome" as marketed online because it's often used to sell unproven treatments. However, intestinal permeability itself is recognized in gastroenterology. The disconnect comes from distinguishing real barrier dysfunction from unsubstantiated claims. I bridge this gap by using validated testing, evidence-based treatments, and clear communication. If you've been diagnosed with IBS, IBD, or other digestive issues by your doctor, we can work collaboratively to address the underlying barrier dysfunction they may not have specifically tested for.
Do I need to buy expensive proprietary supplements or can I use regular brands?
I don't sell supplements in my practice to avoid conflicts of interest. I recommend specific strains or formulations based on research, but you're free to source them wherever you prefer. Many effective supplements are available at reasonable prices from reputable brands. What matters is the right intervention for your situation at the right time, not the price tag. I focus on dietary changes first, then add targeted supplementation only when clearly beneficial. You'll never feel pressured to buy expensive proprietary products.
How is your "leaky gut" treatment different from just treating IBS or food sensitivities?
They're often related. IBS can involve increased intestinal permeability, and barrier dysfunction can contribute to food sensitivities. The difference is that I investigate the underlying mechanisms—why your gut barrier is compromised, what's driving inflammation, and which specific interventions will restore function. Rather than just managing symptoms with medication, we work to repair the barrier, rebalance your microbiome, and address root causes. Many IBS patients have treatable intestinal permeability that conventional approaches miss.
What's the difference between your approach and what I read on wellness blogs?
I base recommendations on peer-reviewed research published in medical journals, not trends or testimonials. While many wellness sites promote extreme elimination diets and dozens of supplements, I use testing to identify your specific issues and create targeted interventions. I'm also honest about uncertainties—if something isn't proven, I'll tell you. My goal is sustainable, evidence-based healing, not quick fixes or lifetime dependency on products. You'll understand the "why" behind every recommendation.
How long does it actually take to see improvement?
Most patients notice some symptom improvement within 2-4 weeks of dietary changes and targeted interventions. Measurable barrier function improvements typically take 3-6 months. Complete healing depends on severity, underlying causes, and consistency with treatment. I don't promise overnight miracles, but patients who commit to the process consistently see meaningful progress. We monitor objectively through symptoms and follow-up testing, adjusting the plan based on your response.
Can I just eliminate gluten and dairy like I've read online?
While removing inflammatory foods can help some people, blanket elimination without testing often isn't necessary and can lead to nutritional deficiencies or unhealthy relationships with food. I prefer to test for actual sensitivities and celiac disease, then create targeted dietary modifications based on your results. Some patients need to avoid gluten and dairy; others don't. Personalization based on evidence, not guesswork, leads to better outcomes and more sustainable changes.
Do you accept insurance, and what about HSA/FSA accounts?
Unfortunately we do not take insurance. HSA and FSA funds can typically be used for consultations, testing and prescribed supplements. We can provide detailed receipts and documentation for insurance reimbursement. Contact our office at (480) 741-2200 to discuss your specific coverage and payment options.
What about peptides like BPC-157 for gut healing?
I stay current on emerging research, including studies showing promise for peptides like BPC-157 for intestinal repair. However, in the U.S., peptides fall between the cracks between supplements and medications -- and BPC-157 is not FDA-approved. That said, it is fairly well-studied with few side effects. It is widely available and works well clinically and anecdotally for "leaky gut" -- especially the oral forms which are made from intestinal juices. Importantly there are contraindications and considerations with a doctor or trained medical professional need to make. While we continue to monitor research, I prioritize evidence-based treatments with established safety profiles and legal standing. Many patients achieve excellent results with proven interventions like targeted supplementation, probiotics and dietary modifications without needing experimental therapies.
