Introduction: Lipedema is a chronic adipose tissue disorder characterized by disproportionate accumulation of subcutaneous fat, primarily affecting the lower extremities. The condition occurs almost exclusively in women and is associated with pain, tissue sensitivity, easy bruising, and progressive functional limitations. These symptoms can impair mobility and negatively affect quality of life.

Background: Endometriosis and lipedema are chronic female-predominant disorders characterized by persistent pain that is frequently disproportionate to anatomical lesion burden. Although traditionally interpreted within distinct lesion-centered frameworks, both conditions exhibit striking clinical and epidemiological parallels, including hormonally modulated symptom dynamics, overlap with central pain syndromes, weak correlation between structural disease severity and pain intensity, and symptom clustering during reproductive transitions such as puberty, pregnancy, and menopause. Methods: This study aims to synthesize clinical, molecular, neuroimmune, and endocrine evidence on the interrelationship between endometriosis and lipedema, and to propose a hypothesis-generating neuroimmune framework linking both conditions. This integrative narrative review conducted a non-systematic literature search in PubMed/MEDLINE, Scopus, and Web of Science, focusing on mechanisms related to chronic pain, mast cell biology, TRPV1 signaling, CGRP-mediated neurogenic inflammation, intracrine steroidogenesis, and peripheral and central sensitization. Results: The review identifies convergent biological characteristics between the two diseases, including mast cell activation, macrophage polarization, endothelial dysfunction, fibrosis, angiogenesis, intracrine estrogen metabolism, and persistent inflammatory signaling. In endometriosis, direct evidence demonstrates increased sensory innervation, nerve growth factor expression, TRPV1 sensitization, CGRP-positive fibers, and mast cell-nerve interactions. In lipedema, convergent upstream mechanisms, including mast cell infiltration, elevated histamine levels, adipose tissue inflammation, and local estrogen activation, support the plausibility of a functionally analogous neuroimmune organization, despite incomplete direct neural characterization. In this context, the mast cell-TRPV1-CGRP axis is proposed as a biologically plausible framework, directly supported in endometriosis and currently hypothetical in lipedema, connecting peripheral sensitization, neurogenic inflammation, hormonal chronodependence, and central nociceptive amplification. The model further conceptualizes pain crises as transient events of instability within a sensitized neuroimmune network and proposes mechanistic phenotypes that integrate gastrointestinal, inflammatory, central, and hormonal triggers. Conclusion: Endometriosis and lipedema may represent topographically distinct manifestations of a shared neuroimmune process operating within hormone-sensitive tissues. Although the evidentiary basis remains asymmetric, with stronger mechanistic support in endometriosis than in lipedema, this framework provides a biologically plausible and experimentally testable model integrating endocrine, immune, neural, and vascular contributors to chronic pain amplification. This perspective supports coordinated translational investigation across reproductive biology, endocrinology, and pain medicine and may contribute to future mechanism-based stratification and therapeutic development. This work is hypothesis-generating and is not intended to establish causality or to provide clinical recommendations; all proposed mechanistic and therapeutic inferences require prospective experimental validation.

Lipedema is a chronic disorder of subcutaneous adipose tissue characterized by disproportionate fat accumulation, pain, and progressive functional impairment, predominantly affecting women. Research remains fragmented across vascular, hormonal, metabolic, and gynecologic perspectives. Recent contributions have advanced specific axes: an international Delphi consensus, a systematic review of hormonal hypotheses, a stromal-vulnerability narrative, and a focused review of adipose biology; but no prior framework has integrated these domains into a single architecture annotated by level of evidence and capable of generating stratified, falsifiable research hypotheses. Here, we propose a hypothesis-generating translational framework that conceptualizes lipedema as the predominant adipose expression of a hormone-sensitive stromal vulnerability. The framework adds a specific molecular convergence axis, ERα/ERβ signaling imbalance interacting with intracrine steroid metabolism (aromatase, 17β-HSDs, AKR1C1), and resolves the disorder into four interacting biological pathways: (i) hormonal transition sensitivity across the female life course; (ii) metabolic– behavioral amplification; (iii) gynecologic–endocrine comorbidity; and (iv) intrinsic stromal–adipose susceptibility. The framework predicts that lipedema and its cognate expressions in hormone-responsive tissues (including gynecologic disease, connective tissue laxity, microvascular dysfunction, neurosensory amplification, and neuropsychological burden) may share a common stromal-endocrine substrate while preserving phenotypic specificity through dominant-pathway combinations. Four features distinguish this framework from prior syntheses: (a) ERα/ERβ signaling imbalance is articulated as a candidate molecular convergence axis linking adipose, gynecologic, connective-tissue, microvascular, and neuro-immune manifestations; (b) intracrine steroid metabolism (aromatase, 17β-HSDs, AKR1C1) is incorporated as the mechanistic anchor of stromal hormone-responsiveness; (c) per-component evidence-level annotation is applied throughout (Level 1A/1B: direct evidence in lipedema; Level 2: observational association; Level 3: mechanistic extrapolation); and (d) stratified, falsifiable research hypotheses are derived from dominant-pathway phenotypes. Two domains, metabolic burden and steroid signaling, emerge as promising translational research domains. Important limitations apply. Direct mechanistic evidence in lipedema-specific tissues is limited; much of the supporting biology is extrapolated from adipose, gynecologic, and metabolic literatures; and most clinical data derive from observational cohorts in referral centers. This article therefore proposes a hypothesis-generating translational framework, not a clinical guideline or therapeutic recommendation.

Lipedema is a chronic adipose tissue disorder characterized by disproportionate and often painful enlargement of the extremities, occurring predominantly in women. Despite increasing clinical recognition, the underlying pathophysiology remains incompletely understood and is likely multifactorial. Existing evidence suggests contributions from vascular alterations, adipose tissue remodeling, inflammatory activation, hormonal influences, and lymphatic dysfunction. This review proposes a hypothesis-generating integrative framework in which lipedema may reflect a regenerative imbalance of subcutaneous adipose tissue. Within this model, genetically and hormonally modulated endothelial permeability could promote activation of perivascular adipose-derived stromal/stem-cell niches and stromal vascular fraction signaling pathways, thereby facilitating coupled angiogenesis and adipogenesis. Progressive adipocyte hyperplasia and hypertrophy may subsequently contribute to inflammatory remodeling, pain generation, and secondary impairment of dermal and subdermal lymphatic drainage. The proposed framework attempts to integrate clinical, histological, imaging, molecular, and endocrine observations into a biologically coherent conceptual model. At the same time, the review emphasizes the current limitations of the available evidence, the heterogeneity of lipedema phenotypes, and the ongoing controversies regarding disease progression, obesity overlap, and the relative role of lymphatic dysfunction. Finally, the potential mechanistic rationale of lymphatic-sparing liposuction is discussed in the context of tissue decompression, restoration of lymphatic transport, and interruption of persistent adipose remodeling. The model presented here should be interpreted as a hypothesis-generating conceptual scaffold requiring prospective validation. Importantly, the present framework should be interpreted as a biologically plausible and hypothesis-generating conceptual model rather than a definitive mechanistic doctrine. Several proposed interactions remain associative and require prospective biological validation.

Lipedema has long been misclassified as a cosmetic concern or a subtype of obesity, leading to delayed diagnosis and suboptimal surgical outcomes. Growing molecular, histopathologic, and imaging evidence supports lipedema as a systemic disorder involving adipose tissue, connective matrix, vascular–lymphatic integrity, and neuroimmune regulation. To integrate these findings into a clinically actionable model, we introduce the concept of Adipoconnective Fragility Syndrome (AFS), framing lipedema as a multisystem condition with direct implications for surgical planning and perioperative management.

Lymphedema and Lipedema are chronic disorders that are often misdiagnosed, leading to complications ranging from infection to impaired mobility. While the genetic basis of lymphedema is well characterized, the genetic contributions to lipedema remain unclear despite clear familial hereditary patterns. This review examines current knowledge on the genetic foundations of both conditions, examining established causative genes in lymphedema and emerging evidence of heritability in lipedema. It also evaluates the role of genetic testing in diagnosis and classification. By emphasizing established findings and highlighting ongoing gaps, this review supports efforts to refine diagnosis and guide therapeutic development.

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: Lipedema is a chronic condition characterized by abnormal fat accumulation, primarily in the lower extremities, affecting mostly women. Despite improvements in diagnosis and treatment, lipedema is often misdiagnosed as obesity or lymphedema. Patients with obesity and lipedema propose a distinct clinical challenge in treating both diseases. Improved recognition and understanding are necessary to enhance diagnosis and treatment outcomes. PURPOSE OF THIS REVIEW: Lipedema is thought to be hormonally driven, often manifesting during puberty, pregnancy, or menopause. It presents as disproportionate fat accumulation in the lower body, often with microvascular changes. Misdiagnosis as obesity or lymphedema leads to ineffective treatments like weight loss programs and bariatric surgery. Effective management involves both conservative and surgical approaches, as well as a tailored strategy for patients with both lipedema and obesity. The focus of this review is to summarize the current literature addressing adequate treatment regimens for patients with both diseases and based on the literature we propose a treatment protocol. CONCLUSION: Patients with concurrent lipedema and obesity propose a distinct clinical challenge, in which early recognition can benefit adequate treatment. A combination of conservative measures and surgical options, particularly liposuction and/or bariatric and metabolic surgery, can be beneficial in treating patients with both diseases. However future research is needed to assess the effect of different treat regimens.

Lipoedema is a chronic, progressive condition characterised by disproportionate fat accumulation in the lower extremities, often misdiagnosed due to symptom overlap with obesity. Weight management is a key component of lipoedema treatment, yet the role of bariatric surgery remains unclear. This systematic review evaluates the impact of bariatric and metabolic surgery (BMS) on lipoedema symptoms, weight loss outcomes, and the need for further interventions. A systematic search of PubMed, Scopus and the Cochrane Library was conducted up to January 2025 following PRISMA guidelines. Studies reporting on patients with lipoedema (or equivalent diagnoses) who underwent BMS were included. Quality was assessed using the Joanna Briggs Institute (JBI) checklist for case reports and the National Heart, Lung and Blood Institute (NHLBI) tool for case series. Seven studies met the inclusion criteria (five case reports, two cohort studies), comprising 51 patients. All underwent BMS, primarily sleeve gastrectomy or Roux-en-Y gastric bypass. One study (n = 31) reported a significant reduction in thigh volume and weight loss comparable to controls. The remaining studies found persistent or worsened lower body disproportionality and no improvement in pain. Postoperative lipoedema diagnoses were common, raising concerns over diagnostic accuracy. Overall weight loss averaged 33.9% total weight loss. Bariatric and metabolic surgery achieves meaningful weight reduction in patients with lipoedema and obesity but does not consistently improve core lipoedema symptoms. Its role remains adjunctive rather than primary. Preoperative identification and documentation of lipoedema features are recommended, with a postoperative plan for adjunct conservative therapies and selective consideration of lymph-sparing liposuction where symptoms persist. Larger prospective studies using standardised definitions and outcome measures are needed to clarify its therapeutic value in this population.

Lipedema is a chronic and progressive disorder characterized by disproportionate fat accumulation, mainly affecting the lower extremities of women, and commonly accompanied by sensations of heaviness, tenderness, and discomfort. While its pathogenesis remains largely unknown, genetic, hormonal, and microvascular factors have been implicated. The condition often coexists with psychological distress, which significantly detracts from the quality of life of affected individuals. Diagnosis is primarily clinical, as no specific biomarkers or imaging modalities have been proven sufficiently reliable for identification. Proposed managements are controversial, although current treatment focuses on symptom management and disease control through conservative methods such as compression and non-invasive device therapies, specialized diets, and physical rehabilitation or surgical treatments. Psychological support is vital in addressing the emotional challenges of the condition. Despite recent advancements in the understanding and management of lipedema, there remains a critical need for further research to establish standardized diagnostic criteria and targeted therapeutic strategies for this debilitating condition.

Background: Emerging evidence suggests that lipedema may share hormonal, inflammatory, and genetic mechanisms with gynecologic diseases, particularly endometriosis. However, the extent and nature of these interrelationships remain poorly characterized, supporting the need for this scoping review. Objectives: To map and synthesize the available evidence on the clinical, pathophysiological, and epidemiological interrelationships between lipedema in women, endometriosis, and other gynecologic diseases. Methods: Searches were conducted in international and regional health databases, including MEDLINE (PubMed), CINAHL, Scopus, Embase, Web of Science, the Cochrane Library, LILACS/VHL, APA PsycInfo, SciELO, Epistemonikos, and La Referencia, as well as grey literature sources and relevant institutional websites. There were no language restrictions. The search period began in 1940, the year in which lipedema was first described by Allen and Hines. Study selection followed a two-stage process conducted independently by two reviewers, consisting of title and abstract screening followed by full-text review. Data extraction was performed using a pre-developed and peer-reviewed instrument covering participants, concept, context, study methods, and main findings. The review protocol was registered in the Open Science Framework. Results: Twenty-five studies from ten countries were included. Synthesized evidence supports the characterization of lipedema as a systemic condition with metabolic and hormonal dimensions. Key findings include symptom onset linked to reproductive milestones, a high frequency of gynecologic and endocrine comorbidities, and molecular features overlapping with steroid-dependent pathologies. These patterns reflect a recent shift from a predominantly lymphovascular paradigm toward a more integrated endocrinometabolic framework. Conclusions: The findings indicate that lipedema clusters with hormone-sensitive gynecologic and endocrine features across reproductive life stages.

Background. Lipedema is a chronic and progressive fat disorder that affects ~11% of the female population. It is characterized by bilateral, disproportionate accumulation of subcutaneous adipose tissue predominantly in the lower body. Symptoms include pain, bruising, swelling, and subcutaneous nodules that are resistant to traditional interventions such as diet and exercise. Aim. The objective of this review is to summarize recent evidence on the characteristics, pathophysiology, diagnosis and treatment of lipedema. Matherial and Methods. A literature search was conducted using the PubMed database. The inclusion criteria were “full free text” and English scientific articles, published between 2015 and 2025. A total of 74 records were found, of which    publications were ultimately included in the review. Results. Awareness of lipedema in the medical field is increasing, but its differential diagnosis still remains a challenge. Lipedema is often unrecognized or misdiagnosed as obesity or lymphedema. Conclusion. This narrative review provides a deeper understanding of lipedema as a serious condition, discusses its pathophysiology and treatment options. The data reveal advances in knowledge, particularly in conservative and surgical treatment with a focus on improving quality of life. However, there is a lack of scientific evidence confirming the safety and efficacy of various treatment methods. Further research is required to ensure the safety and increase the efficacy of treatment for this complex condition known as lipedema.

Lipedema is a chronic inflammatory disorder of adipose tissue that predominantly affects women and is characterized by disproportionate subcutaneous fat accumulation, pain, spontaneous bruising, and significantly impaired quality of life. Although hormonal influences on its pathophysiology have been increasingly recognized, evidence-based treatment options remain limited. Recently, gestrinone has been proposed as an off-label therapy based on hormonal mechanistic hypotheses. A critical narrative review of the literature was conducted using international databases to identify clinical or pharmacological evidence supporting its use in lipedema. No clinical trials, observational studies, case series, or case reports directly evaluating this therapy were identified. Existing proposals rely exclusively on theoretical extrapolations lacking clinical validation. Therefore, current evidence does not support the use of gestrinone in the treatment of lipedema, and its use should be considered experimental until adequately designed clinical studies are available.Keywords: lipedema; adipose tissue; hormone therapy; gestrinone; evidence-based medicine

Lipedema is a chronic, female-predominant disorder of subcutaneous adipose tissue characterized by disproportionate fat expansion, pain, and fibrosis. Despite its high prevalence, the cellular mechanisms underlying lipedema remain poorly understood. While the clinical features have been extensively described, its biology of adipose tissue dysfunction and aberrant intercellular communication is still unclear. In comparison to obesity, lipedema is marked by local dysregulation of adipocyte-stromal and adipocyte-vascular interactions. In this hypothesis perspective, we discuss emerging mechanistic concepts from a cell biology perspective that are particularly relevant to lipedema, focusing on (i) organelle contact site dynamics in adipocytes and their role in lipid handling and stress adaptation; (ii) extracellular vesicle (EV)-mediated crosstalk between endothelial cells, adipocytes, and immune cells as a driver of localized inflammation and fibrosis; and (iii) estrogen-linked signaling pathways that may imprint EV cargo and cellular behavior in a sex-specific manner. By integrating these perspectives, we highlight open experimental settings and mechanistic parallels to other adipose tissue pathologies that help understanding lipedema as a distinct cellular and molecular entity. Investigating how organelle biology, extracellular vesicles communication and hormonal context intersect in adipose tissue may uncover novel biomarkers and therapeutic entry points for this long-neglected condition.
