Endometriosis is a chronic multisystem inflammatory disease characterised by the presence of endometrial-like epithelium and stroma outside the uterine cavity, most commonly within the peritoneal cavity.1 Affecting approximately 10% of reproductive-aged women worldwide, the disease is associated with chronic pelvic pain, infertility and substantial impacts on quality of life and an increased risk of inflammatory bowel disease.2 Gastrointestinal symptoms, including nausea, abdominal pain, bloating (‘endo-belly’) and altered bowel habit, are frequently reported even without overt bowel lesions, highlighting gut-peritoneal interactions in this disease.
