We are more than 37 trillion chemical reactions per second a dynamic, living
symphony of biochemistry and physiology unique to each of us. Achieving optimal health, not merely “good” health, requires understanding this intricate system at an individual level.
As a physician dedicated to root cause medicine for over 44 years, I believe the only way to unlock vibrant, lasting wellness is by identifying and addressing the specific imbalances that drive health challenges, whether they stem from environmental, metabolic, or disease-related sources.
This approach, grounded in comprehensive diagnostics and personalized treatment, is the key to wellness, optimal health, and longevity. It demands a shift from the one-size-fits-all model of conventional care to a deeply individualized journey that respects the complexity of the human body.
The Limitations of Conventional Diagnostics
Most of us are familiar with the routine blood tests ordered by primary care physicians.
These panels measure basic markers like cholesterol or blood sugar, offering a snapshot of health. But a snapshot is not a story. To truly understand what’s happening in your body, a far more comprehensive blood analysis is essential. This should include nutrient levels (vitamins, minerals, amino acids), hormone profiles, inflammatory markers, and toxic metal burdens. For example, deficiencies in nutrients like magnesium or vitamin B12, or elevated levels of toxic metals like lead or mercury, can profoundly disrupt health but often go undetected in standard testing.
Diagnostics must extend beyond bloodwork. The autonomic nervous system, which regulates involuntary functions like heart rate, digestion, and breathing, plays a critical role in overall wellness.
Subtle dysfunctions in this system can contribute to symptoms like fatigue, brain fog, or digestive issues often dismissed by conventional healthcare providers as “normal part of getting older”. Advanced comprehensive assessments, akin to diagnostic scans for a high performance engine, can detect these imbalances. It is important to realize that environmental toxins pesticides, plastics, or toxic metals accumulate in the body over time, silently impairing cellular function. Targeted testing for these toxins is crucial to uncover hidden root causes.
By combining these advanced diagnostics, we gain a clear picture of the unique factors driving an individual’s health challenges, whether they arise from nutrient deficiencies, hormonal imbalances, or environmental exposures.

The GHEN Hypothesis: A Framework for Optimal
Health
Root cause medicine is guided by a framework I call the GHEN Hypothesis, which identifies six mutually inclusive elements essential for cellular function and overall wellness:
1. Nutrition: Every cell requires specific nutrients—vitamins, minerals, amino acids, and enzymes—to operate at its best. Even subtle deficiencies can trigger a cascade of systemic problems, from fatigue to weakened immunity.
2. Oxygenation: Adequate oxygen delivery to tissues is vital for energy production, cellular repair, and detoxification. Poor oxygenation can result from sedentary lifestyles, lung conditions, or circulatory issues.
3. Hormone Balance: Hormones act as the body’s messengers, orchestrating metabolism, mood, and reproduction. Imbalances in cortisol, thyroid, or sex hormones can disrupt multiple systems.
4. Detoxification: Our modern world bombards us with pollutants toxic metals, pesticides, etc. Supporting the body’s natural detox pathways, like the liver and kidneys, is critical to clear these harmful substances.
5. Energy Balance: Mitochondria, the powerhouses of our cells, produce the energy needed for life. Imbalances in mitochondrial function can lead to chronic fatigue, cognitive decline, or muscle weakness.
6. Psychosocial Intervention: The mind-body connection is undeniable. Chronic stress, unresolved trauma, or poor emotional health can manifest as physical symptoms, from headaches to heart disease.
These six pillars are deeply interconnected. A deficiency in one say, poor nutrition can disrupt hormone balance, impair detoxification, or sap energy production, creating a domino effect. Optimal health requires addressing all six elements in a way that’s tailored to the individual’s unique biochemistry and life circumstances.
Personalized Treatment: A Tailored Path to Wellness
Identifying root causes is only the first step. Treatment must be as individual as the patient utilizing comprehensive treatment options. While age, sex, and specific conditions are considerations, they don’t tell the whole story. Generic approaches whether a standard multivitamin or a trendy diet rarely achieve optimal results. Instead, root cause medicine crafts a core plan that integrates lifestyle changes, targeted therapies, and advanced interventions, all guided by the GHEN Hypothesis.
Lifestyle as Medicine: The foundation of any plan includes exercise, sleep, and stress management. Regular physical activity enhances oxygenation, boosts energy balance, and supports detoxification. Quality sleep often undervalued allows the body to repair, regulate hormones, and clear toxins. Stress reduction techniques, such as mindfulness, meditation, or therapy, address the psychosocial element, fostering a harmonious mind-body connection.
Nutrient Repletion: Nutrient deficiencies are surprisingly common, even in those who eat “healthy” diets. Comprehensive testing can reveal specific needs, such as low levels of vitamin D, omega-3 fatty acids, or coenzyme Q10. Oral supplements can help to address these deficits, but in cases of severe deficiency, intravenous nutrient therapy delivering vitamins, minerals, amino acids, and enzymes directly into the bloodstream can rapidly restore cellular function.
Dietary Measures: Food is a cornerstone of health, but no single diet works for
everyone. A personalized nutrition plan, based on biochemical needs, food sensitivities,
and metabolic goals, ensures the body receives optimal fuel. For some, this might mean
a plant-based approach; for others, a high-protein or ketogenic diet.
Advanced Therapies: Cutting-edge tools can accelerate healing and enhance cellular function. Molecular hydrogen inhalation therapy and hydrogen baths reduce oxidative stress, while near-infrared light promotes tissue repair and reduces inflammation. Sonic
wave vibration therapy can improve circulation, alleviate pain, and support musculoskeletal health. These modalities, though not yet mainstream, are powerful allies in the quest for optimal wellness.
Detoxification Support: For patients with toxic metal or environmental toxin burdens, targeted detox protocols are essential. Chelation therapy can safely remove toxic metals, while infrared saunas or lymphatic drainage support the body’s natural detox pathways. These interventions are carefully customized to avoid overwhelming the system.

The Power of Individualization
What makes root cause medicine transformative is its relentless commitment to individualization. Two people with identical symptoms say, chronic fatigue may have entirely different root causes. One might be deficient in iron, while the other struggles with mercury toxicity, imbalanced autonomic nervous system, or chronic infections such as Lyme Disease. By pinpointing these unique drivers, we design treatments that don’t just mask symptoms but resolve them at their source.
This approach requires time, expertise, and a willingness to look beyond conventional medicine’s quick fixes. It also asks patients to become active partners in their health journey, embracing lifestyle changes, dietary shifts, and advanced therapies with an open mind. The reward is profound: not just the absence of disease, but a state of vibrant, optimal health where every cell thrives.
A New Vision for Wellness
Root cause medicine challenges us to rethink how we approach health. By embracing comprehensive diagnostics, the GHEN Hypothesis, and personalized comprehensive treatment strategies, we can move beyond outdated models of care that treat symptoms in isolation. Optimal health is not a luxury it’s a birthright. It begins with understanding your unique biochemistry, addressing your root causes, and committing to a tailored plan that honors the complexity of your body. Take the first step today and unlock a future where you don’t just survive you thrive.
