Title : Medical acupuncture and cognitive behavioural therapy in holistic pain management for endometriosis: A narrative review of mechanisms, evidence, and integrated clinical application
Abstract:
Endometriosis is a chronic, oestrogen-dependent neuro-inflammatory condition affecting approximately 10% of reproductive-age women, characterised by debilitating pelvic pain, dysmenorrhoea, dyspareunia, dyschezia, and profound impacts on physical, psychological, and social wellbeing. Conventional management including hormonal therapies, analgesics, and surgery provides incomplete symptom relief for many, carries significant side-effect profiles, and does not fully address the central sensitisation, pain catastrophising, anxiety, depression, and functional disability that perpetuate the chronic pain cycle. There is growing recognition that endometriosis pain is multifactorial, involving peripheral inflammation, neural plasticity, autonomic dysregulation, and psychological distress creating a compelling rationale for integrated, multimodal care that combines physical and psychological interventions. This narrative review synthesises the physiological and psychological mechanisms through which medical acupuncture and cognitive behavioural therapy (CBT) act on complementary but non-overlapping pain pathways, evaluates the current clinical evidence base for each approach, and proposes an integrated model of holistic pain management for endometriosis. Acupuncture exerts peripheral and central analgesic effects by stimulating endogenous opioid release, modulating prostaglandin and cytokine production, reducing sympathetic overactivity, and inhibiting central sensitisation with meta-analyses demonstrating significant reductions in pain severity (SMD = −1.10, 95% CI −1.45 to −0.75, p < 0.001) and improved quality of life. CBT targets the cognitive-affective dimension of pain by reducing pain catastrophising, enhancing pain self-efficacy, modifying maladaptive illness beliefs, and addressing comorbid anxiety and depression with recent RCTs showing medium-to-large effect sizes for improved pain outcomes and health-related quality of life (β = −0.58, p = 0.01). When combined, acupuncture and CBT address the biological, psychological, and social dimensions of pain in a synergistic manner: acupuncture reduces nociceptive input and physiological hyperarousal, creating an improved neurobiological state in which CBT can more effectively restructure pain-related cognition, emotional response, and behavioural function. Both interventions are safe, well-tolerated, and have no known drug interactions, making them suitable adjuncts alongside conventional pharmacotherapy and surgery. Despite the absence of combined-intervention trials to date, the convergent mechanistic rationale and complementary evidence bases strongly support the integration of acupuncture and CBT within holistic endometriosis care pathways. Further research including pilot feasibility studies and definitive RCTs evaluating combined versus single-intervention approaches is warranted to establish optimal sequencing, treatment duration, and cost-effectiveness.
