Chronic Disease & Fatigue Mosman

Struggling with chronic fatigue, fibromyalgia, or autoimmune disease in Mosman? Dr Ranga identifies the root cause and creates a personalised recovery protocol.

Are you exhausted by unexplained fatigue and chronic illness?

You’ve been to your GP. You’ve had the blood tests. They come back ‘normal’ — yet you feel anything but. Persistent fatigue, widespread pain, recurring infections, and a body that just won’t respond to conventional treatment.

If this sounds familiar, you are not alone. Millions of Australians are living with unresolved chronic disease and fatigue conditions that the standard medical system struggles to address — not because the illness isn’t real, but because the root cause has never been properly investigated.

At World of Health, serving Mosman and the Lower North Shore, Dr Ranga Premaratna has spent over 35 years doing exactly that: finding and addressing the true biochemical root causes of chronic disease and fatigue.

Chronic Disease and Fatigue Conditions We Support

Dr Ranga’s integrative approach supports clients experiencing a wide range of chronic conditions, including:

Whether your condition is newly diagnosed or you have been managing symptoms for years, our clinic offers a fresh perspective grounded in nutritional biochemistry, functional medicine testing, and personalised clinical protocols.

Why Conventional Medicine Often Falls Short

Standard medical appointments average 15 minutes. That is rarely enough time to investigate the complex, interconnected causes of a chronic disease management plan tailored to your unique biochemistry.

Conditions like chronic fatigue syndrome, fibromyalgia, and autoimmune disease are multifactorial. They are driven by combinations of factors including:

Without investigating all of these factors together, most people end up with symptom management rather than genuine recovery.

Dr Ranga's Approach to Chronic Disease and Fatigue

Dr Ranga is a highly qualified Food and Nutritional Scientist with 30 years of clinical experience, specialising in immune function, metabolic health, toxicity, and chronic disease.

His unique consultation process begins with a comprehensive assessment that goes far beyond a standard appointment. Using advanced functional pathology testing and Dark Field Microscopy of live blood, he builds a detailed picture of what is happening inside your body at a cellular level.

This allows him to identify the specific, complex root causes driving your symptoms  and design a personalised Return to Wellness protocol that addresses them directly.

Dr Ranga’s integrative protocols combine:

  1. Nutritional and Ayurvedic medicine
  2. Targeted supplementation based on your test results
  3. Anti-inflammatory dietary protocols
  4. Functional pathology testing
  5. Bio-Energetic Technology
  6. Lifestyle and stress management support

Chronic Fatigue Syndrome (CFS): Getting Real Answers

Chronic fatigue syndrome is one of the most misunderstood and under-diagnosed conditions in Australia. Symptoms such as post-exertional malaise, cognitive difficulties (brain fog), disrupted sleep, and widespread pain are often dismissed or attributed to stress and anxiety.

Dr Ranga investigates the physiological drivers of CFS, including immune system dysregulation, viral reactivation, mitochondrial dysfunction, and nutritional depletion. His protocols for chronic fatigue treatment focus on restoring cellular energy production and immune resilience — not just managing symptoms.

If you have been asking ‘why am I always tired and have no energy?’, our clinic can provide the comprehensive investigation your health deserves.

Fibromyalgia: A Holistic Treatment Protocol

Fibromyalgia is characterised by widespread musculoskeletal pain, fatigue, sleep disturbances, and cognitive difficulties. Despite affecting an estimated 2-3% of Australians, it remains poorly understood and often inadequately treated.

Natural options for treating fibromyalgia exist, and Dr Ranga’s holistic protocol for fibromyalgia addresses the underlying drivers of inflammation, nervous system dysregulation, and nutritional deficiency. Many clients find that a combination of targeted nutritional therapy, dietary changes for fibromyalgia, and lifestyle support significantly reduces their symptom burden.

Autoimmune Disease: Calming an Overactive Immune System

Conditions such as rheumatoid arthritis, multiple sclerosis, and psoriatic arthritis share a common thread: the immune system attacking the body’s own tissues. Rather than solely suppressing the immune response, Dr Ranga investigates why it became dysregulated in the first place.

His integrative approach to autoimmune disease explores the role of gut health, food sensitivities, environmental toxin exposure, and nutritional status in driving immune dysfunction — and creates a plan to address these factors systematically.

If you have been diagnosed with an autoimmune condition and want to explore integrative options alongside your conventional treatment, we welcome you to book a consultation.

Frequently Asked Questions: Chronic Disease and Fatigue

While rheumatologists and GPs are often involved, many fibromyalgia patients find that an integrative medicine practitioner who specialises in nutritional medicine and functional testing offers the most comprehensive assessment. Dr Ranga brings over 35 years of experience in identifying the root causes of complex chronic conditions.

Chronic fatigue treatment with integrative medicine involves advanced testing to identify root causes (such as viral reactivation, nutrient depletion, gut health issues, or heavy metal toxicity), followed by a personalised nutritional and lifestyle protocol to restore cellular energy and immune function.
While autoimmune conditions are complex, significant symptom reduction and immune system rebalancing is possible through targeted dietary, nutritional, and lifestyle interventions. Dr Ranga’s protocols are designed to address the underlying drivers and support the best possible quality of life.

There is no single ‘best’ diet, as requirements are highly individual. However, an anti-inflammatory dietary approach that addresses gut health, eliminates inflammatory triggers, and ensures adequate micronutrient intake forms the basis of Dr Ranga’s nutritional protocols for chronic fatigue.
