Lipedema is a chronic and progressive adipose tissue disorder characterized by disproportionate fat accumulation, microvascular dysfunction, chronic inflammation, and progressive fibrosis. Despite its prevalence and significant impact on quality of life, current therapeutic approaches remain largely symptomatic and fail to address the underlying biological mechanisms of the disease. Emerging evidence suggests that lipedema should be understood as a multifactorial condition involving genetic susceptibility, endothelial alterations, immune dysregulation, and extracellular matrix remodeling. In this context, pharmacological strategies targeting these pathways have gained increasing attention. Metformin, through activation of AMP-activated protein kinase (AMPK), exerts antifibrotic and immunometabolic effects, including inhibition of TGF-β signaling, reduction of extracellular matrix deposition, and modulation of adipose tissue inflammation. In parallel, incretin-based therapies, particularly glucagon-like peptide-1 (GLP-1) receptor agonists and dual GLP-1/GIP agonists such as tirzepatide, have demonstrated pleiotropic effects that extend beyond weight reduction, including improvements in metabolic homeostasis, reduction of systemic inflammation, and enhancement of endothelial function. These therapies appear to act through complementary mechanisms, with metformin primarily targeting tissue remodeling and fibrosis, and incretin-based therapies exerting broader systemic effects on metabolism, inflammation, and vascular integrity. This review proposes a hypothesis-generating mechanistic framework, supporting a shift from weight-centric and symptomatic approaches toward disease-modifying strategies. Although current evidence in lipedema is largely indirect, the convergence of experimental and clinical data provides a strong rationale for further investigation. Future studies should focus on evaluating combined therapeutic approaches and identifying biomarkers that reflect fibrosis, inflammation, and microvascular dysfunction, with the aim of developing targeted and personalized treatments for this complex disorder.

Background: The aim of the study was to verify the effectiveness of a 5-week intensive protocol of multilayer bandaging alone or in combination with diet, applied to the clinical practice of lipedema. Methods: 114 women with lipedema were studied, divided into three groups: 35 women were treated with multilayer bandaging in biweekly sessions for 5 weeks, 48 were treated with the same bandaging protocol combined with an anti-inflammatory diet, and 31 women received no treatment. The effect on anthropometry, lower limb volume, pain caused by the tissue fold, and subjective symptoms were evaluated. Results: Women who completed the 5-week intensive protocol of multilayer bandaging showed a statistically significant reduction in all observed parameters: body weight, waist and hip circumference, lower limb volume, pain, and subjective symptoms. The group of women treated with multilayer bandaging and diet showed a significantly greater reduction in lower limb volume and body weight. The treatments were effective regardless of age, BMI, clinical stage, and the presence of fovea in both groups. The wearing time with the multilayer bandage had a positive correlation in the group treated with bandage in combination with diet. Conclusion: A 5week intensive protocol of multilayer bandaging of the lower limbs is an effective treatment for reducing the symptoms and clinical signs of lipedema at all stages of the disease, even in the absence of edema. Adding nutritional therapy during the bandaging cycle increases the effectiveness of the treatment on the volume of the affected extremities and body weight.

Lipedema is a chronic, estrogen-sensitive adipose tissue disorder characterized by disproportionate subcutaneous fat accumulation, fibrosis, inflammation, and resistance to fat mobilization. Despite its high prevalence, lipedema remains poorly understood and frequently misdiagnosed. This narrative review proposes a novel pathophysiological model in which menopause acts as a critical turning point in the progression of lipedema, driven by estrogen receptor imbalance (ERβ predominance over ERα), intracrine estrogen excess, and adipose tissue dysfunction. We demonstrate how menopauseinduced estrogen deficiency amplifies adipose tissue dysfunction by suppressing ERα signaling, enhancing ERβ activity, and disrupting mitochondrial function, insulin sensitivity, and lipid oxidation. Concurrently, the upregulation of aromatase and 17β-HSD1, combined with the suppression of 17β-HSD2, sustains localized estradiol excess, perpetuating inflammation, fibrosis, and immune dysregulation. The molecular signature observed in lipedema closely mirrors that of other estrogen-driven gynecological disorders, such as endometriosis, adenomyosis, and uterine fibroids. Understanding these molecular mechanisms highlights the pivotal role of menopause as a catalyst for disease progression and provides a rationale for targeted therapeutic strategies, including hormonal modulation and metabolic interventions. This review reframes lipedema as an estrogen receptor– driven gynecological disorder, offering a new perspective to improve clinical recognition, diagnosis, and management of this neglected condition.

Lipedema is a chronic medical condition characterized by a symmetric buildup of adipose tissue (fat) in the legs and arms. A common but under-recognized disorder, Lipedema may cause pain, swelling, easy bruising, and impaired mobility. During the past decade, Lipedema, which occurs almost exclusively in women, has been demonstrated to be a disease that is distinct from obesity, lymphedema, cellulite, and other adipose conditions. The Lipedema Research Roadmap identifies recommendations to strengthen and grow Lipedema research. It presents a forward-looking summary of gaps in knowledge and opportunities for research and development, sourced from “Lipedema: A Current Understanding of Its Pathology and Natural History” (Lipedema Foundation; preprint, forthcoming), as well as input from authors and advisors. Recommendations are organized into six chapters covering key objectives: fostering the research environment, developing reporting standards and best practices, improving diagnosis, broadening understanding of the biology of the disease, identifying potential treatments, and enhancing epidemiology. The Research Roadmap development process incorporated input from more than 60 stakeholders, including researchers, clinicians, and patients. 24 external reviewers provided more than 1,300 comments and recommended edits.
