This review examined how often bladder pain syndrome (chronic bladder inflammation and pain) occurs together with gynecological conditions like endometriosis and vulvodynia in women. The researchers found that these conditions frequently overlap—for example, about 48% of women with endometriosis also have bladder pain syndrome. They also found that pelvic floor muscle dysfunction is very common in bladder pain patients, affecting up to 87% of them.
This study is relevant to ME/CFS because both conditions involve chronic pain, dysfunction of multiple body systems, and potential pelvic/gynecological involvement. Understanding the high comorbidity between BPS/IC and other pain conditions suggests that comprehensive, systems-based evaluation may benefit ME/CFS patients who experience similar overlapping symptoms and pain disorders.
This review does not establish causal mechanisms linking these conditions or prove that one disorder causes another. The study identifies associations and prevalence rates but does not clarify whether shared pathophysiology, common triggering factors, or diagnostic overlap explain the high comorbidity. It also does not directly address ME/CFS patients, limiting generalizability to that population.
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 →
