Increased Intestinal Permeability (Leaky Gut)
Chronic digestive symptoms, unexplained food sensitivities, and persistent inflammation throughout your body aren't random occurrences—they may signal that your intestinal barrier isn't functioning properly. Research shows that increased intestinal permeability plays a role in numerous gastrointestinal conditions including celiac disease, Crohn's disease, and IBS, which is why our team focuses on comprehensive gut barrier assessment and restoration as a foundation for lasting digestive wellness.

What Exactly Is Increased Intestinal Permeability?
Increased intestinal permeability, commonly referred to as "leaky gut," occurs when the tight junctions between intestinal cells become compromised, allowing larger molecules, bacteria, and toxins to pass through the intestinal wall into the bloodstream. In a healthy gut, this barrier is selectively permeable—allowing beneficial nutrients through while blocking harmful substances. When this barrier becomes compromised, it can trigger immune responses and systemic inflammation that extend far beyond the digestive system.
Types of Barrier Dysfunction and Their Characteristics
Intestinal permeability can manifest in different ways depending on the underlying cause and affected areas. Each type requires specific assessment and targeted intervention strategies.
| Type | Primary Mechanism | Common Symptoms | Considerations |
|---|---|---|---|
| Inflammatory-Mediated | Chronic inflammation disrupting tight junctions | Abdominal pain, diarrhea, systemic inflammation | Often associated with IBD, celiac disease, or chronic infections |
| Stress-Induced Permeability | Stress hormones affecting gut barrier function | Digestive symptoms during stress, mood-gut connection | Involves gut-brain axis disruption and nervous system dysregulation |
| Toxin-Related Damage | Environmental toxins or medications compromising barrier | Food sensitivities, chemical sensitivities, fatigue | May involve NSAIDs, alcohol, or environmental toxin exposure |
| Microbiome-Driven | Dysbiotic bacteria producing inflammatory compounds | Bloating, irregular bowel movements, brain fog | Often includes SIBO, candida overgrowth, or bacterial imbalances |
Why Increased Intestinal Permeability Impacts More Than Digestion
When the intestinal barrier becomes compromised, the effects extend throughout the entire body due to the gut's central role in immune function and nutrient absorption. A compromised gut barrier can allow inflammatory molecules to enter the bloodstream, triggering immune responses that may contribute to autoimmune conditions, mood disorders, and systemic inflammation. This can disrupt hormone production, neurotransmitter synthesis, and nutrient absorption—affecting energy levels, cognitive function, skin health, and overall vitality.
Common Signs of Increased Intestinal Permeability Include:
Chronic digestive issues (bloating, gas, irregular bowel movements)
Multiple food sensitivities or intolerances
Frequent infections or poor immune function
Skin problems (eczema, acne, rashes)
Fatigue, brain fog, or cognitive difficulties
Joint pain or muscle aches
Mood changes, anxiety, or depression
Seasonal allergies or environmental sensitivities
Autoimmune condition diagnosis
Nutrient deficiencies despite adequate dietary intake
Diagnostic Options at Whole Gut Health
Finding the root cause of leaky gut is often apparent through careful evaluation of a patient’s medical history and symptoms. At times comprehensive assessment is necessary. At Whole Gut Health, we use advanced diagnostics to evaluate intestinal barrier integrity and contributing factors.
Testing options may include:
Comprehensive Stool Analysis to assess microbiome balance, inflammation markers, and digestive function.
SIBO Breath Testing to identify bacterial overgrowth that may compromise gut barrier function.
Applied Kinesiology also known as muscle testing to determine root causes and triggers. Applied Kinesiology allows a for a much broader ability to diagnose than laboratory tests.
Osteopathic Visceral Evaluation to assess physical restrictions, symmetry, and subtle motions of the internal organs. This provides information on the function of the organs as well as their associated meridians.
Organic Acids Testing to evaluate for fungal overgrowth and metabolic dysfunction.
Functional Lab Work including nutrient assessments, inflammatory markers, and immune system evaluation. There are several popular tests which from our experience do not provide value in diagnosis. We always use strategic and only necessary testing.
We design testing protocols based on your specific symptoms and health history to identify all factors contributing to barrier dysfunction.
Our approach
Why Whole Gut Health is different
At Whole Gut Health, we go beyond conventional symptom management and traditional functional medicine protocols. We trust your body's innate ability to heal itself when given the right support.
In Dr. Shustina's many years of practice, she has seen that many digestive diseases have their root cause in emotional traumas and unhealed wounds. When these underlying causes are healed, the body can heal from the inside out in a lasting way.
We focus on the mind-gut connection, incorporating energy healing techniques, personalized nutrition that evolves as you heal, and integrative approaches addressing mind, body, and spirit. If this resonates with you, contact our office to schedule your consultation and take the first step on your healing journey.
