Your gut does far more than digest food — it serves as a foundation for your immune system, hormone balance, and even emotional health. At the Stengler Center for Integrative Medicine, located near Leucadia and North County San Diego, Dr. Mark Stengler, NMD, MS, and his experienced team provide comprehensive, natural care for patients seeking lasting digestive healing and overall vitality.

Dr. Stengler is a nationally recognized integrative and naturopathic physician, often referred to as America’s Natural Doctor. With over two decades of clinical experience, he has helped thousands of patients overcome chronic digestive challenges through evidence-based, holistic medicine that blends the best of modern science and natural healing.

At the Stengler Center, gut health care is more than symptom management — it’s about uncovering and correcting the root causes of digestive dysfunction. Dr. Stengler’s whole-body approach recognizes that the gut influences nearly every aspect of health, from energy production and mental clarity to immune defense and hormonal stability.

Many chronic conditions — including fatigue, autoimmune disorders, skin problems, and even anxiety — often begin with poor gut function. When the digestive system is inflamed or imbalanced, it can trigger widespread effects throughout the body. By restoring balance at the gut level, Dr. Stengler helps patients rebuild the foundation for true wellness and lasting vitality.

The Gut–Body Connection

Inside your digestive system lives an extraordinary ecosystem known as the microbiome — trillions of beneficial bacteria that help digest food, produce essential nutrients, support the immune system, and influence your mood and brain health. When this delicate balance of good and bad bacteria is disrupted (a condition called dysbiosis), your body can experience a ripple effect of health issues.

This is because the gut isn’t just connected to digestion — it’s linked to the entire body through the brain-gut axis, a communication pathway between the nervous system and the intestines. Stress, poor diet, infections, and certain medications can disrupt this axis, affecting mood, sleep, and even cognition.

Common Gut Health Conditions Treated at the Stengler Center

The Stengler Center for Integrative Medicine provides comprehensive, diagnostic, and natural treatments for a wide range of gut-related conditions. Patients from Leucadia and surrounding coastal communities seek care for both digestive and systemic concerns that often begin in the gut.

Digestive Disorders:

• Irritable Bowel Syndrome (IBS): Characterized by bloating, cramping, and irregular bowel movements, often linked to stress and food sensitivities.
• Leaky Gut Syndrome (Intestinal Permeability): A weakened intestinal barrier allowing toxins and undigested food particles to enter the bloodstream, triggering inflammation.
• Small Intestinal Bacterial Overgrowth (SIBO): Excess bacteria in the small intestine leading to bloating, pain, and nutrient malabsorption.
• Gastroesophageal Reflux Disease (GERD): Chronic acid reflux caused by poor stomach function or microbial imbalance.
• Chronic Constipation or Diarrhea: Often signs of dysbiosis or poor digestive enzyme activity.

Systemic Issues Linked to Gut Imbalance:

Because gut dysfunction affects immune and hormonal systems, Dr. Stengler also treats related conditions, including:

• Autoimmune disorders (such as Hashimoto’s thyroiditis, rheumatoid arthritis, and lupus)
• Chronic fatigue and brain fog related to inflammation and nutrient depletion
• Food sensitivities and intolerances contributing to headaches, bloating, or skin irritation
• Mood changes, anxiety, and depression, often connected to disruptions in serotonin production within the gut

Advanced Testing for Digestive Function

Healing begins with understanding. At the Stengler Center for Integrative Medicine, Dr. Mark Stengler uses advanced, science-based diagnostic testing to uncover the root causes of gut dysfunction—because lasting relief comes from knowing precisely what’s happening inside your body. Patients from Leucadia and the surrounding coastal communities benefit from a deep, investigative approach that looks beyond surface symptoms.

Here are some of the key diagnostic tools used at the Stengler Center:

• Comprehensive Stool Analysis:
  This in-depth test evaluates your gut microbiome—the balance between beneficial and harmful bacteria. It also measures digestion markers, inflammation, and the presence of pathogens like parasites or yeast. The results help guide targeted treatment for conditions such as IBS, SIBO, and leaky gut.
• Food Sensitivity and Allergy Testing:
  Chronic inflammation and bloating can be caused by hidden food sensitivities. These tests identify immune reactions to common foods, allowing Dr. Stengler to create personalized nutrition plans that calm the immune system and reduce inflammation.
• SIBO Breath Testing:
  Small Intestinal Bacterial Overgrowth (SIBO) is a leading cause of bloating, gas, and abdominal discomfort. This non-invasive breath test detects excess hydrogen and methane gases produced by bacteria in the small intestine, confirming whether SIBO is the underlying issue.
• Intestinal Permeability Testing:
  Commonly referred to as “leaky gut testing,” this diagnostic tool assesses the health of your intestinal lining. When the gut barrier becomes compromised, toxins and food particles can enter the bloodstream, triggering inflammation throughout the body.
• Adrenal and Thyroid Testing:
  Hormones profoundly influence digestion. By testing cortisol (the body’s primary stress hormone) and thyroid function, Dr. Stengler identifies whether hormonal imbalance is contributing to poor digestion or low metabolism.
• Micronutrient and Inflammatory Markers:
  These panels assess nutrient absorption efficiency, vitamin and mineral status, and systemic inflammation levels. Deficiencies or chronic inflammation can impair healing, and correcting them helps restore digestive function naturally.

Personalized Gut Health Treatment Plans

At the Stengler Center, every treatment plan is individualized. Dr. Stengler believes that no two digestive systems—or patients—are alike. His integrative approach to gut health combines nutrition, natural medicine, and targeted lifestyle adjustments to correct imbalances and strengthen the body’s ability to heal itself.

• Nutritional Therapy:
  Dr. Stengler crafts personalized meal plans to reduce inflammation, balance the microbiome, and support gut lining repair. These nutrition plans often feature anti-inflammatory foods, prebiotic fibers, and healing broths that nourish both the body and the beneficial gut bacteria.
• Targeted Supplementation:
  Evidence-based natural compounds are used to promote healing. This may include probiotics for microbial balance, digestive enzymes for nutrient absorption, L-glutamine and zinc carnosine to repair the intestinal lining, and herbal antimicrobials to eliminate harmful bacteria.
• Lifestyle Modifications:
  Stress, sleep, and toxin exposure all influence digestive health. Patients receive guidance on stress management techniques, proper hydration, and gentle detoxification practices to support the body’s natural repair processes.
• Medical Integration:
  For patients requiring additional testing or medical imaging, Dr. Stengler collaborates with gastroenterologists and other specialists. This ensures that each patient receives the most comprehensive, coordinated care possible.
• Education and Empowerment:
  Healing the gut is a journey. Dr. Stengler’s patients are educated about their condition and equipped with the knowledge they need to maintain long-term digestive and overall health. Follow-up visits help track progress and ensure results are sustainable.

Natural Solutions for IBS and Leaky Gut in Leucadia

Two of the most common digestive challenges patients face are Irritable Bowel Syndrome (IBS) and Leaky Gut Syndrome, and while they share similar symptoms, they differ in origin and physiology.

• IBS is primarily a functional disorder—meaning it involves changes in how the digestive system moves and communicates, often influenced by stress, diet, or microbial imbalance.
• Leaky Gut, or intestinal permeability, is a structural issue—the gut lining becomes weakened, allowing particles and toxins to pass into the bloodstream, sparking inflammation and immune reactions.

Many patients diagnosed with “IBS” actually have underlying leaky gut or SIBO that conventional testing may overlook. This is why Dr. Stengler’s comprehensive evaluations and functional testing are so important—they help identify the root causes that standard medicine can miss.

To restore gut function and balance, Dr. Stengler follows a proven four-phase gut healing protocol:

1. Remove: Eliminate harmful bacteria, yeast, parasites, and inflammatory foods that irritate the digestive tract.
2. Replace: Restore digestive enzymes and stomach acids needed for proper nutrient breakdown.
3. Reinoculate: Rebuild the gut microbiome with beneficial probiotics and prebiotic fibers.
4. Repair: Strengthen the intestinal lining using natural nutrients like L-glutamine, aloe, zinc, and collagen.

This systematic approach helps reduce inflammation, improve absorption, regulate bowel movements, and rebuild intestinal integrity. Over time, patients report improved digestion, clearer thinking, more stable energy, and reduced food sensitivities.

For residents of Leucadia and North County San Diego, this natural path to digestive wellness offers lasting results—without unnecessary medications or short-term fixes.
