This review article examines how experiences of violence and stress may trigger or worsen conditions like ME/CFS, fibromyalgia, and irritable bowel syndrome—illnesses that involve pain, exhaustion, mood changes, memory problems, and sleep issues. The authors explain that stress affects the brain and body's hormone and nervous system function, which may make people more vulnerable to developing these conditions. Understanding this connection could help us recognize how violence exposure affects long-term health.
For ME/CFS patients, this review highlights that trauma and violence exposure may be significant contributing factors to disease onset and severity through measurable changes in stress-response systems. This perspective validates patient experiences and underscores the need for trauma-informed care and further investigation into neurobiological mechanisms linking adverse experiences to symptom expression in ME/CFS.
This review does not establish causality or quantify the magnitude of risk; it identifies association and proposed mechanisms rather than proving that violence directly causes ME/CFS. The review does not provide individual patient outcomes or comparative risk data between violence-exposed and unexposed populations. It cannot distinguish whether stress dysregulation precedes symptom onset or develops as a consequence of chronic illness.
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 →
