Beyond Symptom Management: Addressing the Root Causes of ME/CFS
Chronic fatigue syndrome (ME/CFS) is one of the most misunderstood and under-treated conditions in modern medicine. Patients often endure years of dismissal, misdiagnosis, and ineffective treatment before finding a physician who takes their condition seriously. The conventional approach — if one is offered at all — typically consists of cognitive behavioral therapy and graded exercise therapy, interventions that many patients find inadequate or even harmful.
At St. George Hospital, we take a fundamentally different approach. Under the direction of Dr. Julian Douwes, our chronic fatigue program is built on the premise that ME/CFS is a complex, multi-system disease with identifiable root causes — and that addressing those causes is the path to meaningful recovery.
Understanding the Root Causes of Chronic Fatigue
Modern research has identified several interconnected pathological mechanisms that drive ME/CFS. In most patients, multiple factors are operating simultaneously, which is why a single-therapy approach rarely succeeds.
Mitochondrial Dysfunction
Mitochondria — the energy-producing organelles within every cell — are frequently impaired in ME/CFS patients. Research has demonstrated reduced mitochondrial membrane potential, impaired oxidative phosphorylation, and decreased ATP production in this patient population. When cells cannot produce adequate energy, systemic fatigue is the inevitable result.
Key mitochondrial impairments observed in ME/CFS include:
- Reduced Complex I and Complex III activity in the electron transport chain
- Increased oxidative stress damaging mitochondrial membranes
- Depletion of CoQ10, NAD+, and other mitochondrial cofactors
- Impaired fatty acid beta-oxidation
Chronic Viral Reactivation
Many ME/CFS cases are triggered by viral infections — Epstein-Barr virus (EBV), HHV-6, cytomegalovirus (CMV), and enteroviruses are the most commonly implicated. In susceptible individuals, these viruses are not fully cleared but instead persist in a latent state, periodically reactivating and driving immune activation, inflammation, and fatigue (Rasa et al., 2018).
Immune Dysregulation
ME/CFS is characterized by a distinctive pattern of immune dysfunction: elevated pro-inflammatory cytokines, reduced natural killer (NK) cell function, and a shift from Th1 to Th2 immune dominance. This creates a state of chronic, low-grade immune activation that consumes energy and produces persistent symptoms without effectively resolving the underlying triggers.
Hormonal Imbalances
The hypothalamic-pituitary-adrenal (HPA) axis is frequently disrupted in ME/CFS, leading to:
- Low cortisol production (adrenal insufficiency)
- Thyroid dysfunction (particularly low T3 conversion)
- Sex hormone imbalances (low testosterone, progesterone, or DHEA)
- Growth hormone deficiency
These hormonal disruptions both result from and perpetuate the fatigue cycle.
Gut Dysbiosis and Intestinal Permeability
An increasing body of research links ME/CFS to altered gut microbiome composition and increased intestinal permeability (“leaky gut”). Bacterial translocation from the gut into the bloodstream triggers immune activation and systemic inflammation, contributing to the symptom burden.
Our Diagnostic Approach: Testing Before Treating
Effective holistic treatment of ME/CFS begins with thorough diagnostic evaluation. At St. George Hospital, we utilize a comprehensive testing protocol that includes:
Functional Blood Analysis
- Comprehensive metabolic panel with mitochondrial markers
- Viral serology and reactivation markers (EBV VCA, EA, EBNA; HHV-6 IgG/IgM; CMV)
- Immune function panels (NK cell activity, lymphocyte subsets, cytokine profiles)
- Complete hormonal assessment (cortisol diurnal curve, thyroid panel with rT3, sex hormones, DHEA-S)
- Oxidative stress markers (lipid peroxides, glutathione, SOD, CoQ10)
- Nutrient status (vitamin D, B12, folate, iron/ferritin, magnesium, zinc, selenium)
Gut Microbiome Analysis
- Comprehensive stool analysis with bacterial diversity mapping
- Intestinal permeability markers (zonulin, LPS antibodies)
- Short-chain fatty acid profiles
Environmental and Toxicological Screening
- Heavy metal assessment (mercury, lead, cadmium, arsenic)
- Mold exposure markers (mycotoxin panels)
- Environmental chemical burden (pesticides, plasticizers)
Treatment Modalities: Our Holistic Approach
Interval Hypoxia-Hyperoxia Training (IHHT)
IHHT is one of the most promising therapies for mitochondrial rehabilitation in ME/CFS patients. By alternating periods of reduced oxygen (hypoxia) and enriched oxygen (hyperoxia) during a comfortable, resting session, IHHT stimulates mitochondrial biogenesis — the production of new, healthy mitochondria — and triggers the selective elimination of damaged mitochondria (mitophagy).
Research has shown that IHHT can improve exercise tolerance, reduce fatigue severity, and enhance cellular energy production over a course of 10–15 sessions (Serebrovska et al., 2021).
NAD+ Intravenous Therapy
Nicotinamide adenine dinucleotide (NAD+) is a critical coenzyme in mitochondrial energy production. ME/CFS patients frequently have depleted NAD+ levels. Intravenous NAD+ therapy bypasses the digestive system to deliver this essential molecule directly to cells, supporting ATP synthesis, DNA repair, and sirtuin-mediated cellular maintenance.
Ozone Therapy
Medical ozone therapy — delivered as major autohemotherapy (MAH) — has immunomodulatory and metabolic effects that are particularly relevant for ME/CFS. Ozone therapy improves oxygen utilization at the cellular level, stimulates antioxidant enzyme production, and modulates immune function. Many patients report improved energy and reduced brain fog within the first few sessions.
Neurofeedback
Neurofeedback therapy addresses the neurological component of ME/CFS, including sleep disruption, brain fog, and autonomic dysregulation. By training the brain’s electrical activity toward healthier patterns, neurofeedback can improve sleep quality, cognitive function, and stress resilience — all critical factors in ME/CFS recovery.
Hormonal Optimization
Based on comprehensive endocrine testing, we develop individualized hormonal support protocols that may include bioidentical cortisol support, thyroid optimization (including T3 supplementation when appropriate), DHEA, and other hormonal interventions tailored to each patient’s specific deficiencies.
Pacing and Lifestyle Medicine
We recognize that activity management (pacing) is essential for ME/CFS patients. Unlike graded exercise therapy, which can trigger post-exertional malaise (PEM), our approach emphasizes staying within the patient’s energy envelope while gradually expanding capacity as mitochondrial function improves. Nutritional optimization, sleep hygiene, and stress reduction are integrated into every treatment plan.
Our Inpatient Program for Chronic Fatigue
St. George Hospital offers a comprehensive inpatient program for ME/CFS patients, typically lasting 2 to 3 weeks. This program includes:
- Thorough diagnostic evaluation (days 1–2)
- Individualized treatment plan development based on findings
- Daily therapeutic sessions (IHHT, IV therapies, ozone, neurofeedback as indicated)
- Nutritional support and supplementation
- Medical supervision and daily physician assessment
- Discharge planning with a personalized home protocol
The advantage of an inpatient setting is that patients can receive intensive, daily treatment without the energy expenditure of traveling to and from appointments — a critical consideration for individuals with limited functional capacity.
Frequently Asked Questions
How is your approach different from conventional ME/CFS treatment?
Conventional treatment for ME/CFS typically focuses on symptom management — pain medication, antidepressants, and behavioral therapy. Our approach at St. George Hospital focuses on identifying and treating the underlying causes: mitochondrial dysfunction, chronic infections, immune dysregulation, and hormonal imbalances. By addressing root causes, we aim for meaningful functional improvement rather than merely coping with symptoms.
How long does treatment take, and when do patients see results?
Our inpatient program typically lasts 2 to 3 weeks. Many patients notice improvements in energy, sleep quality, and cognitive function during the inpatient stay. However, recovery from ME/CFS is usually a gradual process. Mitochondrial rehabilitation, in particular, takes time — most patients continue to improve for 3 to 6 months after completing the intensive program, especially when following the prescribed home protocol.
Is ME/CFS the same as post-COVID fatigue?
There is significant overlap. Many patients with long COVID meet the diagnostic criteria for ME/CFS. The underlying mechanisms — mitochondrial dysfunction, immune dysregulation, viral persistence — are often similar. At St. George Hospital, we evaluate each patient individually, but our therapeutic approach addresses the same pathological processes regardless of the triggering event.
Can you treat ME/CFS patients who are severely affected (bedbound)?
Yes. Our inpatient setting is designed to accommodate patients with varying levels of functional capacity. For severely affected patients, we modify the treatment schedule to respect their energy limitations while still delivering essential therapies. The hospital environment eliminates the need for patients to manage activities of daily living during their treatment period.
Do you accept international patients for the ME/CFS program?
Absolutely. We treat patients from over 90 countries. Our international patient team assists with medical record review, treatment planning, visa documentation, travel arrangements, and accommodation for accompanying family members. Contact us to begin the consultation process.
