From Dismissal to Distress: Mapping the Psychological Link Between Diagnostic Delay, Medical Invalidation, and Health Anxiety in Polyendocrine Metabolic Ovarian Syndrome (PMOS)

Polyendocrine metabolic ovarian syndrome (PMOS), previously known as polycystic ovary syndrome (PCOS), is a complex endocrine and metabolic condition with reproductive, dermatological, metabolic, and psychological dimensions. In May 2026, an international consensus process published in The Lancet established PMOS as the new name, intended to better represent the condition’s multisystem features and avoid the misleading implication that ovarian cysts define the syndrome (Teede et al., 2026). Alongside clinical management, the diagnostic journey can shape how individuals interpret symptoms, assess health threats, and engage with healthcare. Research on people previously diagnosed with PCOS documents delayed diagnosis, dissatisfaction with information, and challenging healthcare experiences (Gibson-Helm et al., 2017; Soucie et al., 2021). This conceptual review integrates these findings with health psychology and medical sociology to propose a pathway linking diagnostic uncertainty and perceived medical invalidation with disrupted illness representations, reduced trust, health-related worry, bodily monitoring, and varied health-seeking responses. The framework draws particularly on Leventhal’s Common-Sense Model of Self-Regulation and the concepts of testimonial and hermeneutical injustice. It also considers weight stigma, digital health searching, reassurance seeking, and healthcare avoidance. These links are presented as plausible, testable relationships rather than an established causal sequence, because direct PMOS-specific evidence for the entire pathway remains limited. Implications include respectful symptom validation, transparent diagnostic communication, shared decision-making, and psychological support that does not minimise legitimate physical symptoms. Future research should test the proposed model longitudinally and evaluate interventions designed to improve both patient experience and continuity of care.
