Recent insights into 3 underrecognized conditions: Myalgic encephalomyelitis-chronic fatigue syndrome, fibromyalgia, and environmental sensitivities-multiple chemical sensitivity.
Hu, Howard, Baines, Cornelia · Canadian family physician Medecin de famille canadien · 2018
Quick Summary
This review article examines three conditions that doctors often overlook or misunderstand: ME/CFS, fibromyalgia, and multiple chemical sensitivity. The authors discuss why these conditions are frequently underrecognized and how they affect patients' lives. They highlight that these conditions are real medical problems that deserve proper attention and care.
Why It Matters
This paper is important because it addresses a critical problem in ME/CFS care: many primary care physicians do not recognize or adequately diagnose the condition. By highlighting ME/CFS alongside fibromyalgia and multiple chemical sensitivity, the authors help normalize discussions about these conditions and advocate for better clinical recognition. This can lead to earlier diagnosis, better patient outcomes, and reduced diagnostic delays that patients often experience.
Observed Findings
- ME/CFS, fibromyalgia, and multiple chemical sensitivity are frequently underrecognized by primary care physicians
- Patient symptoms in these conditions are often dismissed or attributed to psychiatric causes
- Clinicians lack standardized training in recognizing and diagnosing these complex conditions
Inferred Conclusions
- Improved physician education and awareness are necessary to increase recognition of these underdiagnosed conditions
- Primary care practitioners should be equipped with knowledge of the clinical features and diagnostic approaches for ME/CFS and related conditions
- Validating these conditions as legitimate medical problems is essential for improving patient outcomes and reducing diagnostic delay
Remaining Questions
- What specific training interventions most effectively improve physician recognition of ME/CFS in primary care settings?
- How do patients experience delays in diagnosis, and what are the clinical consequences of these delays?
- What are the shared biological mechanisms, if any, between ME/CFS, fibromyalgia, and multiple chemical sensitivity?
- How can healthcare systems be restructured to better support diagnosis and management of these conditions?
What This Study Does Not Prove
As a narrative review article, this paper does not present original research data or conduct controlled studies. It does not prove the mechanisms underlying ME/CFS or establish new diagnostic criteria. It cannot determine causation for any aspect of these conditions, only discuss existing knowledge and clinical observations from the published literature.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
