Stigma perceived by patients with functional somatic syndromes and its effect on health outcomes - A systematic review.
Ko, Charlotte, Lucassen, Peter, van der Linden, Britt et al. · Journal of psychosomatic research · 2022 · DOI
Quick Summary
This review examined whether patients with functional somatic syndromes like ME/CFS, fibromyalgia, and IBS experience more stigma and negative health effects than patients with other medical conditions. The researchers found that ME/CFS and fibromyalgia patients did experience higher levels of stigma compared to patients with clearly explained medical conditions, and stigma was linked to worse health outcomes in all groups studied.
Why It Matters
This systematic review confirms that ME/CFS patients face substantial stigma that correlates with worse health outcomes, validating patient experiences and highlighting a treatable psychosocial barrier to care. Understanding stigma's role in ME/CFS is critical for developing interventions and advocating for improved medical recognition and support.
Observed Findings
- Patients with ME/CFS experienced higher levels of stigma compared to patients with comparable explained medical conditions
- Patients with fibromyalgia experienced higher levels of stigma compared to patients with comparable explained medical conditions
- Patients with IBS did not consistently experience higher stigma levels than comparator groups
- All included studies found correlations between perceived stigma and negative physical and mental health outcomes
- Stigma is not unique to functional somatic syndromes; patients with explained medical conditions also experience stigma
Inferred Conclusions
- ME/CFS and fibromyalgia patients face disproportionate stigma that adversely affects their health
- Stigma's health consequences may be more pronounced in functional somatic syndromes, though this requires direct comparative research
- Multiple patient populations experience stigma, suggesting it is a widespread healthcare system issue
Remaining Questions
- Does stigma directly cause worse health outcomes in ME/CFS, or is it a marker of other underlying psychosocial stressors?
- Why does IBS not show consistent higher stigma levels compared to explained conditions when CFS and FM do?
What This Study Does Not Prove
This study does not establish whether stigma causes worse health outcomes or merely correlates with them, nor does it definitively prove that ME/CFS patients experience more negative health consequences from stigma than patients with explained conditions. The small number of CFS-specific studies (n=1) limits conclusions specific to ME/CFS.

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 →
