Lipedema is a chronic and progressive adipose tissue disorder characterized by symmetrical fat accumulation, pain, tenderness, and easy bruising, predominantly affecting women. Increasing evidence suggests that chronic low-grade inflammation and impaired resolution of inflammation may contribute to its pathophysiology. Maresin-1 is a specialized pro-resolving lipid mediator with potent anti-inflammatory and tissue-protective properties; however, its role in lipedema remains largely unknown. This cross-sectional observational study aims to evaluate serum Maresin-1 levels in women with lipedema and to investigate their associations with pain severity, inflammatory markers, central sensitization, and quality of life. Serum Maresin-1 levels and clinical characteristics will be compared among women with lipedema, obese women without lipedema, and healthy controls to explore the potential value of Maresin-1 as a biomarker in lipedema.
