Lipedema is a chronic, underdiagnosed adipose disorder marked by disproportionate fat accumulation, pain, and impaired mobility. Misdiagnosis as obesity or lymphedema delays care and increases morbidity. We systematically reviewed clinical features, diagnostic criteria, and management options (conservative and surgical). A comprehensive search of the PubMed database was conducted in January 2025 for English-language articles published from January 1950 to January 2023 using the keywords "lipedema" or "lipoedema." Additional references were identified via manual review of relevant systematic reviews. Two independent reviewers screened studies and graded quality using a modified Oxford scale. Of 339 articles, 61 met the inclusion criteria. Most were observational cohorts, case series, or expert consensus, with few randomized trials. Conservative therapies, including ketogenic or Rare Adipose Disorders (RAD) diets, compression therapy, and aquatic exercise, were associated with reduced pain and swelling (Grade 2A-2B). Tumescent liposuction showed the strongest evidence for sustained symptom improvement, mobility, and quality of life (Grade 1 recommendation, evidence quality 2-3). Lipedema is a distinct, progressive condition requiring early recognition and intervention. Conservative therapies may provide partial relief, but tumescent liposuction remains the most effective treatment. Standardized diagnostic criteria, validated patient-reported outcomes, and clearer guidelines are needed to harmonize care and improve long-term outcomes.

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.

BackgroundLipedema is a chronic disorder involving abnormal accumulation of subcutaneous fat, primarily in the lower limbs. Liposuction is an effective treatment, but postoperative complications such as fluid retention and seroma formation are common. While the use of surgical drains is well established in other areas of plastic surgery, their role in lipedema liposuction remains unclear.MethodsThis prospective observational study involved 50 consecutive patients with stage II or III lipedema who underwent lower leg liposuction. A novel passive drainage technique was used, involving glove drains fashioned from sterile, powder-free nitrile gloves and inserted through existing liposuction incisions. Drain duration, postoperative swelling, and complications, particularly seroma formation, were evaluated.ResultsAll patients completed follow-up with no major complications. Glove drains remained in place for an average of 2.4 ± 0.5 days. Only 2 patients (4%) developed seromas requiring single aspiration. No infections, hematomas, or lymphatic complications were recorded. Patients reported reduced swelling and discomfort compared to historical cases without drains.ConclusionPassive glove drains appear to be a simple, safe, and effective method to manage postoperative fluid collections after lipedema liposuction of the lower legs. The technique may lower the risk of seroma formation and promote early recovery, characterized by reduced postoperative edema, improved patient comfort, and an uncomplicated short-term postoperative course. Further controlled studies are needed to validate these findings and establish standardized drainage protocols in lipedema surgery.

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.

Background:  Lipedema is a progressive subcutaneous adipose tissue disorder predominantly affecting women. Characterized by painful nodules and inflammation, it impairs mobility and quality of life. Traditional nonsurgical treatments currently offer limited relief and necessitate additional interventions. This study aimed to evaluate the efficacy of SMiLE (Softening, Mobilization, Liposuction, Extraction), a lipedema reduction surgery (LRS) technique. This technique combines lymphatic-sparing liposuction with manual lipedema extraction to comprehensively remove lipedema nodules. Methods:  Sixty-two women who underwent LRS with the SMiLE technique by the primary author participated in the study and completed an online survey. Data were collected on prior medical history related to lipedema development and comorbidities and outcome measures such as pain, activities of daily living, and quality of life before and after surgery. Results:  The findings demonstrate significant improvements in patients’ daily lives following surgery. Pain levels decreased by an average of 73.9%, with the most notable reduction in the buttock shelf (81.3%). Mobility improved for 93% of participants who had faced challenges before LRS, and quality-of-life assessments indicated a 47.5% reduction in the negative impact of lipedema postsurgery. Conclusions:  The SMiLE technique offers an advancement in the surgical management of lipedema by enabling the effective removal of lipedema tissue. Alongside a reduction in pain and improvement in mobility, this method addresses physical and psychological burdens. This study suggested that the SMiLE technique could be considered an option as part of a comprehensive approach to treating patients with lipedema.

Objective: The aim of this study was to identify the demographic and clinical characteristics of patients with lipedema who presented to our outpatient clinic in Çorum, thereby contributing to defining the lipedema case profile in our country. Material and Methods: We included 80 female patients diagnosed with lipedema at the physical medicine and rehabilitation outpatient clinic of our hospital between January 2020-July 2023. Data on age, body mass index (BMI), lipedema type-stage, and symptoms were collected from medical records. Laboratory evaluations, including hemogram, 25-OH vitamin D, vitamin B12, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and lower limb venous doppler ultrasound results were also obtained from medical records. Results: The mean age was 46.46±9.72 years and BMI was 32.12±4.84. Type 2 lipedema was the most common, followed by Type 1 and Type 3. Stage 2 lipedema was seen in 63.8% of the patients, stage 1 in 21.2%, and stage 3 in 15%. Common symptoms included pain, swelling, fatigue, and leg heaviness. The mean CRP was 4.88±2.89 mg/L, ESR was 18.58±10.06 mm/h, 25-OH vitamin D was 18.73±12.95 ng/dl, and vitamin B12 was 359.74±155.12 pg/ml. Venous insufficiency was present in 50% of the patients. Lipedema stage showed significant positive correlations with age (r: 0.284, p: 0.011), BMI (r: 0.307, p: 0.006), and ESR (r: 0.271, p: 0.015).Conclusion: Patients presenting with swelling and pain in the lower limbs should always be assessed for lipedema, and it should also be considered that venous insufficiency and vitamin deficiencies may coexist in these patients.

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 lipoedema patients with obesity but does not consistently improve core lipoedema symptoms. Its role remains adjunctive rather than primary. Larger prospective studies using standardised definitions and outcome measures are needed to clarify its therapeutic value in this population.

ObjectivesLipedema is a chronic condition that predominantly affects women, leading to painful, disproportionate fat distribution in the limbs. This systematic review and meta-analysis aimed to characterize health-related quality of life (HRQoL) across multiple domains in individuals with lipedema.MethodsWe systematically reviewed studies from inception to 3 July 2025 in MEDLINE (via PubMed) and Cochrane Controlled Register of Trials (CENTRAL) that primarily assessed HRQoL in individuals with lipedema. Data were extracted from studies using HRQoL assessment scales. The methodological quality of included studies was assessed using an adapted version of the Newcastle-Ottawa Scale for cross-sectional studies. The review protocol was pre-registered with PROSPERO (CRD42024590792). A random-effects meta-analysis was conducted to compute pooled mean HRQoL scores across various domains.ResultsFourteen cross-sectional studies involving nine countries and 3851 participants were included. The meta-analysis found significant impairments in multiple HRQoL domains: physical functioning (61.19, 95% CI: 56.77-65.60), pain (51.77, 95% CI: 45.01-58.53), social functioning (63.24, 95% CI: 58.44-68.04), emotional well-being (64.19, 95% CI: 59.86-68.52), and energy/fatigue (43.50, 95% CI: 39.32-47.68).ConclusionLipedema significantly affects HRQoL, with major deficits in physical, emotional, and social functioning. These findings highlight the need for greater clinical awareness and comprehensive management strategies, including both physical and psychological interventions, to improve the quality of life for individuals with lipedema. Further research is needed to explore long-term effects and optimize treatment approaches.

INTRODUCTION: Lipedema causes abnormal fat accumulation in the limbs, leading to pain, functional impairment, and body image disturbance. Nowadays, various liposuction techniques are available. The wet technique is increasingly being considered as the gold standard; however, comparative data between the dry and wet methods remain limited. We evaluated the efficacy of liposuction and compared outcomes between dry and wet approaches. Our analysis focused on surgical characteristics, complication rates, and clinical outcomes including pain relief, functional improvement, and esthetic satisfaction, with comparisons made between preoperative and 12-month postoperative results. METHODS: Besides surgical data extraction, patient-reported outcome measures (PROMs) were obtained through three different standardized questionnaires to assess pain relief, function gain, and esthetic satisfaction. RESULTS: Both techniques were effective, demonstrating overall improvements in pain, function, and body image, when comparing pre and postoperative outcomes. Lipoaspirate volumes were comparable between the groups. Operative time was significantly shorter in the wet technique group. Short-term complication rates did not differ between dry and wet techniques. While both techniques led to a global improvement, the wet technique showed greater potential in pain reduction and better esthetics satisfaction 12 months post-surgery. CONCLUSION: Lipedema is a complex disease that is still poorly understood. Liposuction may offer symptomatic relief regardless of the technique used, but the wet technique demonstrates better postoperative results, with improved PROMs and fewer complications. The treatment of lipedema requires a multidisciplinary approach, while conservative therapy remains the first-line option, surgical treatment by wet liposuction should be considered for its significant potential in improving functional outcomes and as an effective therapeutic option.

Background/Objectives: Lipedema is a chronic, progressive adipo-fascial disorder characterized by connective tissue dysfunction, fibrosis, microangiopathy, and adipose tissue proliferation. Although lipedema has traditionally been described as a regionally confined disorder, emerging evidence suggests that it may reflect a broader stromal and connective tissue dysfunction. It is therefore plausible that anatomical regions not historically associated with lipedema may also exhibit alterations consistent with this dysfunctional stromal pattern. From this perspective, breast tissue-rich in fibro-glandular and stromal components-represents a compelling model in which to investigate whether such features are present. The breast, with its complex fibro-glandular and stromal architecture, represents a physiologically plausible site of involvement; however, its structural features in lipedema have never been systematically examined. The primary aim of this study was therefore to determine whether breast tissue-rich in fibro-glandular and stromal components-shows recurrent imaging or histopathological features suggestive of lipedema-related involvement. A secondary aim was to compare the frequency of these findings with patterns typically reported in healthy screening populations. Methods: This retrospective cross-sectional study analyzed 62 women (mean age: 44 ± 8 years), obtained between September and November 2025, with a clinical diagnosis of lipedema who voluntarily provided breast imaging reports (ultrasound, mammography, or magnetic resonance imaging, MRI). Results: The findings revealed a remarkably high prevalence of fibro-glandular parenchyma (45%), multiple diffuse cysts (42%), microcalcifications (21%), and fibroadenomas (43.5%), with frequencies substantially exceeding those documented in healthy screening populations. Additional features included significant breast asymmetry or tuberous morphology (6%), reactive or sclero-lipomatous lymph nodes (19%), and recurrent stromal hyperplasia on biopsy. Histological evaluations (n = 9) consistently showed fibroproliferative alterations, including stromal hypercellularity, adenosis, fibroepithelial lesions, apocrine metaplasia, and pseudoangiomatous stromal hyperplasia, suggesting a shared extracellular matrix-related dysplastic phenotype between lipedema-affected breast tissue and peripheral adipose tissue. Conclusions: These findings support the hypothesis that lipedema may express a characteristic breast phenotype driven by stromal and extracellular matrix dysregulation. If confirmed in larger controlled studies, these recurrent alterations could contribute to improved diagnostic frameworks and raise awareness of lipedema as a systemic connective tissue disorder with underrecognized breast manifestations.

INTRODUCTION: Lipedema is a chronic inflammatory disease characterized by symmetrical deposition of adipose tissue in the upper and lower limbs, disproportionate to the trunk. It primarily affects women. The objective of this study was to evaluate the effects of surgical treatment in patients with lipedema who are refractory to conservative management. METHODS: We conducted a systematic review and single-arm meta-analysis in accordance with PRISMA guidelines. Retrospective studies involving patients who underwent surgical treatment after failing clinical management were included. Means and proportions were pooled using the inverse variance method and logit transformations, and heterogeneity was assessed using the I2 statistic. RESULTS: We included 6 studies comprising 429 patients, with follow-up ranging from 6 months to 44 months. In this meta-analysis, surgical treatment with tumescent liposuction resulted in significant clinical improvements for patients with lipedema. The pooled mean preoperative pain score was 5.64 (95% CI: 3.67-8.69), which decreased to 1.19 (95% CI: 0.91-4.22) postoperatively. Sensitivity to touch or pressure was reduced from a preoperative mean of 5.77 (95% CI: 4.10-8.10) to 1.96 (95% CI: 1.17-3.29) after surgery. Swelling scores improved from 5.47 (95% CI: 3.73-8.02) preoperatively to 2.14 (95% CI: 1.31-3.48) postoperatively, while restriction of movement scores decreased from 3.76 (95% CI: 2.48-5.72) to 0.77 (95% CI: 0.36-1.64). CONCLUSION: The results of this single-arm meta-analysis, which included six studies and 429 patients with lipedema refractory to clinical treatment and undergoing surgical intervention, demonstrate that tumescent liposuction is associated with reductions in postoperative pain and edema, as well as improvements in cosmetic outcomes, quality of life, and mobility. The duration of follow-up was adequate to capture relevant clinical outcomes and adverse events. However, lipedema remains a condition that requires further high-quality studies to define the optimal therapeutic approach.

Background: Lipedema is a progressive disorder of subcutaneous connective tissue, predominantly affecting women, and characterized by an increase in subcutaneous adipose tissue, particularly in the lower body. This study aims to explore the gut microbiota (GM) profile in lipedema patients to characterize the associated GM and compare it with the control group. Methods: A prospective randomized case-control pilot study was conducted from September 2023 to May 2024, involving 55 Caucasian women, aged 20-60. The participants were divided into two groups: 35 with lipedema (LIPPY) and 20 controls (CTRL). Body composition was assessed using Dual X-ray Absorbimetry (DXA), and GM analysis was performed through 16S rRNA gene sequencing. Results: LIPPY subjects showed increased Intramuscular Adipose Tissue (IMAT) and reduced Lean Mass (LM)/Fat Mass (FM) ratios. While alpha and beta diversity metrics did not differ significantly between groups, differential abundance analysis identified a significant reduction in Eggerthellaceae (Log Fold Change (LFC) = -0.19, p = 0.04) and enrichment of Propionibacteriaceae (LFC = +0.18, p = 0.009) and Acidaminococcaceae (LFC = +0.32, p = 0.013) in the LIPPY group. Genus-level analysis showed a significant reduction in Blautia and Ruminiclostridium (LFC = -0.32 and -0.02; p = 0.02 and 0.04) and enrichment of Anaerostipes, Propionibacterium, and Phascolarctobacterium (LFC = +0.07, +0.17, and +0.34; p = 0.02, 0.005, 0.005, respectively). In correlation analyses, within LIPPY, Eggerthellaceae correlated negatively with Body Mass Index (BMI) (ρ = -0.61, p < 0.05) and positively with Appenicular (Appen) LM/Weight and AppenLM/BMI (ρ = +0.43 and +0.41, p < 0.05), while Anaerostipes correlated positively with these lean mass indices (ρ = +0.40, p < 0.05). In CTRL, only Anaerostipes showed a significant negative correlation with BMI (ρ = -0.64, p < 0.05). Conclusions: This study provides the first evidence of a distinct GM profile in LIPPY, with notable links to adverse body composition markers such as IMAT. Trial Registration: Trial registered on 24 June 2013 with ClinicalTrial.gov (NCT01890070).

Background/Objectives: Lipedema is a chronic disorder that affects almost exclusively women and is characterized by bilateral, symmetrical accumulation of subcutaneous fat, typically in the buttocks, hips, and lower limbs, and in some cases the arms. The primary objective of this study was to describe the clinical and anatomical manifestations of lipedema, together with the associated physical and psychological comorbidities, in a large Spanish cohort. Methods: Descriptive study of 1803 patients aged ≥ 17 years who attended two clinics in Spain between January 2022 and November 2024. Results: The mean age was 42.9 years (SD: 11.3), and 60.6% of patients were diagnosed during their reproductive years. The mean body mass index was 28.6 (SD: 6.2), and 87.6% presented a gynoid fat distribution. A total of 46.6% were classified as Schingale stage IV or V. The most frequent comorbidities were chronic low-grade inflammatory alterations and connective tissue damage. Particularly suspected high intestinal permeability (99%), bilateral trochanteric pain region (97.4%), iliotibial band involvement, and ligamentous hyperlaxity (95.8%). Thyroid disorders, inflammatory ovarian dysfunction, and psychological impairment were also common. Conclusions: Lipedema is a complex condition that extends beyond lower-limb adipose tissue and is associated with multiple comorbidities. This study also presents a novel approach to clinical assessment that may help physicians gain a deeper understanding of this pathology and formulate etiological hypotheses that will need to be tested.

Lipedema is a chronic adipose tissue disorder primarily affecting women, marked by abnormal, symmetrical, and disproportionate accumulation of subcutaneous fat in the lower limbs and sometimes in the arms, with hands and feet typically spared. Frequently misdiagnosed as lymphedema or obesity, lipedema presents with pain, easy bruising, bilateral nonpitting edema, and swelling that worsens throughout the day. We present two cases: Two middle-aged women reported longstanding bilateral lower limb swelling, pain, and varicose veins, without significant comorbidities. Clinical examination revealed characteristic disproportionate fat distribution and negative Stemmer's sign. Laboratory investigations and lymphoscintigraphy excluded other causes of edema. Imaging confirmed subcutaneous thickening, fat stranding, and varicosities. Both patients were advised to have conservative management including compression therapy, limb elevation, physiotherapy and dietary counseling; one exhibited significant limb volume reduction. Our report underscores the importance of recognizing lipedema for early diagnosis and effective management to prevent progression and complications.

Objectives: This study aimed to evaluate the clinical efficacy of transfer energy capacitive and resistive (TECAR) therapy in females with Stage 2 lipedema, focusing on limb circumference, pain, functional status, and quality of life. Patients and methods: A prospective, randomized controlled trial was conducted with 30 female patients diagnosed with Stage 2 lipedema between September 2024 and May 2025. Participants were randomized to a TECAR group (n=15; mean age: 52.7±13.1 years; range 39 to 66 years) or a control group (n=15; mean age: 45.9±12.9 years; range, 37 to 59 years). Both groups received compression garments and a structured exercise program. The TECAR group additionally underwent six TECAR sessions over three weeks. Outcomes included lower limb circumference, Visual Analog Scale for pain, Lower Extremity Functional Scale, and Lymphedema Quality of Life Questionnaire-Leg, assessed at baseline and at one and three months after treatment. Results: The groups were comparable at baseline for age (p=0.163) and body mass index (31.85±4.08 kg/m² in the TECAR group and 30.02±4.08 kg/m² in the control group; p=0.112). The TECAR therapy resulted in greater reductions in lower limb circumference compared to standard care, with a statistically significant and sustained improvement observed only in the supramalleolar region at three months (p<0.05). A significant short-term reduction in pain was observed at one month (p=0.003) only in the TECAR group, but this effect was not maintained at three months (p>0.05). Functional scores showed a nonsignificant trend toward improvement (p=0.058). The overall quality of life score improved significantly in the TECAR group (p=0.002), although no individual Lymphedema Quality of Life Questionnaire subdomain reached statistical significance (p>0.05). Conclusion: As an adjunct to standard care, TECAR therapy appears to reduce pain and limb volume and enhance overall quality of life in Stage 2 lipedema. Further long-term studies are needed to confirm these findings.

BACKGROUND: Lipedema is a chronic, progressive adipose tissue disorder that predominantly affects women and is characterized by disproportionate fat accumulation, pain, and edema. Hormonal fluctuations are frequently reported as triggers or modulators of symptoms, but the impact of exogenous hormones, especially hormonal contraceptives, remains poorly defined. OBJECTIVE: This study aimed to investigate the association between hormonal contraceptive use and the presence, severity, and self-reported worsening of lipedema symptoms in Brazilian women. METHODS: This observational, cross-sectional study was conducted at Amato - Instituto de Medicina Avançada using a structured online questionnaire applied between August and November 2025. We included women aged 18 years or older, residing in Brazil, with suspected or confirmed lipedema who provided electronic consent and completed core sections on lipedema symptoms, hormonal history, and contraceptive use. Questionnaires with less than 50% of core items answered, duplicate entries, and biologically implausible values were excluded. Symptom (0-8) and quality of life (0-15) scores were calculated. Self-reported changes in symptoms after starting hormonal contraceptives were analyzed as a four-level variable and as a binary worsening variable. Free text on side effects and timing of onset was categorized with natural language processing. Statistical analyses included chi-squared tests, Spearman correlations, and logistic and linear regression. RESULTS: A total of 637 women were included (mean age 41.8±8.7 years; mean body mass index (BMI) 28.9±6.4 kg/m²); 77.1% had a confirmed diagnosis of lipedema and 92.3% were current or previous users of hormonal contraceptives. Among users, 58.8% reported symptom worsening after starting contraceptives (34.5% severe; 24.3% slight), 40.3% reported no change, and 0.9% reported improvement (p<0.001). Free text analysis showed that 15.1% reported onset of lipedema symptoms temporally coinciding with contraceptive initiation. In multivariable analysis, a higher baseline symptom score was the strongest independent predictor of worsening, while duration of contraceptive use was not associated with risk. Pain intensity and BMI were the main independent predictors of quality of life impact. CONCLUSIONS: In this large sample of Brazilian women with suspected or confirmed lipedema, hormonal contraceptive use was frequently associated with self-reported worsening of symptoms, and a substantial minority reported symptom onset around contraceptive initiation. Women with higher baseline symptom burden appeared particularly vulnerable. These findings support individualized contraceptive counseling for women with lipedema and highlight the need for prospective studies with objective measures to clarify causality and mechanisms.

Background: Lipedema is a progressive adipofascial disorder marked by painful nodular fat deposition that is often mistaken for obesity. While tumescent liposuction reduces limb volume with relative lymphatic safety, persistent large, painful lobules frequently remain, and excisional strategies risk iatrogenic lymphatic injury. We evaluated the application of intraoperative indocyanine green (ICG) lymphography to identify and preserve lymphatic channels during debulking surgery for symptomatic lipedema. Methods: We conducted a single-center case series (University of Pittsburgh Medical Center, July 2023–December 2024) of adults with lipedema refractory to conservative therapy who underwent a selective dermato-lipectomy (lobule/skin excision) with or without tumescent liposuction. Patients with clinical lymphedema or dermal backflow in ICG were excluded. Near-infrared ICG (SPY-PHI) was used for pre-incision mapping and real-time intraoperative guidance; lymphatic trajectories were marked and spared during lobule excision. Primary measures included dermal backflow patterns and lymph node transit time; secondary outcomes were complications and symptom burden (Lymphedema Life Impact Scale, LLIS) through ≥24 months. Results: Eight patients (five female/three male; mean age 49.5 ± 14.4 years; median BMI 52.65 kg/m2) underwent ICG-guided surgery. Preoperatively, linear lymphatic patterns were visualized up to the knee in all patients, but dermal backflow patterns could not be visualized in 83% from the level of the knee to the groin. Still, 67% demonstrated inguinal nodal uptake (mean transit 24 min), suggesting preserved lymphatic transport. All cases achieved intraoperative confirmation of intact lymphatic flow after debulking. The mean liposuction aspirate was 925 ± 250 mL per lower extremity; the mean excision mass was 2209 ± 757 g per lower extremity. Complications included two superficial cellulitis events (25%) and one wound dehiscence (12.5%); no hematomas or skin necrosis occurred. No patient developed clinical or imaging evidence of iatrogenic lymphedema during follow-up. Conclusions: Intraoperative ICG lymphography is a practical adjunct for lymphatic-sparing debulking of symptomatic lipedema, enabling real-time identification and preservation of superficial collectors while addressing focal lobules. This hybrid approach—targeted tumescent liposuction followed by ICG-guided superficial dermato-lipectomy—was associated with meaningful symptom improvement and a low morbidity in this early series.
