This narrative review examines the complex relationship between obesity and endometriosis, noting that while higher BMI is associated with lower diagnosis rates, adipose tissue may exacerbate disease progression through hormonal disturbances and chronic inflammation. The authors evaluate the potential therapeutic role of glucagon-like receptor agonists (GLP-1RAs), which are known to promote weight loss and reduce inflammation, in managing endometriosis symptoms. Evidence from preclinical studies and observational data suggests these agents might indirectly influence the disease course by modulating metabolic and inflammatory pathways, although no randomized clinical trials have yet confirmed their efficacy specifically for this indication. This paper is centrally about endometriosis — specifically exploring the mechanistic links between obesity and the disease, as well as the potential off-label application of GLP-1 receptor agonists for symptom management.

Abstract

Endometriosis is a chronic, estrogen-dependent inflammatory disease affecting approximately 10% of women of reproductive age and is one of the leading causes of chronic pelvic pain and infertility. The relationship between obesity and endometriosis remains controversial. Although epidemiological studies indicate that endometriosis is diagnosed less frequently in women with a higher body mass index (BMI), excessive adipose tissue may promote disease progression through hormonal disturbances, chronic inflammation, and altered metabolic activity of adipose tissue. This review summarizes the current evidence regarding the mechanisms linking obesity and endometriosis and discusses the potential role of glucagon-like peptide-1 receptor agonists (GLP-1RAs) in the treatment of this disease. In addition to their well-established efficacy in the management of obesity and type 2 diabetes, GLP-1RAs have been shown to promote weight loss, improve metabolic parameters, and reduce chronic inflammation. Available experimental and observational evidence suggests that these mechanisms may indirectly influence the course of endometriosis by modulating the chronic inflammation and the metabolic disturbances associated with obesity. To date, no randomized clinical trials have evaluated the efficacy of GLP-1 receptor agonists in women with endometriosis, and most of the available evidence is derived from preclinical studies, observational studies, and analyses conducted in patients with polycystic ovary syndrome (PCOS). Current evidence suggests that GLP-1RAs represent a promising area of research; however, their role in the treatment of endometriosis requires confirmation in well-designed clinical trials.
