Lipedema is a painful loose connective tissue disorder characterized by a bilaterally symmetrical fat deposition in the lower extremities. The goal of this study was to characterize the adipose-derived stem cells (ASCs) of healthy and lipedema patients by the expression of stemness markers and the adipogenic and osteogenic differentiation potential. Forty patients, 20 healthy and 20 with lipedema, participated in this study. The stromal vascular fraction (SVF) was obtained from subcutaneous thigh (SVF-T) and abdomen (SVF-A) fat and plated for ASCs characterization. The data show a similar expression of mesenchymal markers, a significant increase in colonies (p < 0.05) and no change in the proliferation rate in ASCs isolated from the SVF-T or SVF-A of lipedema patients compared with healthy patients. The leptin gene expression was significantly increased in lipedema adipocytes differentiated from ASCs-T (p = 0.04) and the PPAR-γ expression was significantly increased in lipedema adipocytes differentiated from ASCs-A (p = 0.03) compared to the corresponding cells from healthy patients. No significant changes in the expression of genes associated with inflammation were detected in lipedema ASCs or differentiated adipocytes. These results suggest that lipedema ASCs isolated from SVF-T and SVF-A have a higher adipogenic differentiation potential compared to healthy ASCs.

Background: The aim of this study was to investigate the Turkish adaptation, validity, and reliability of the Patient Benefit Index-Lymphedema (PBI-L) ensuring direct assessment of the benefit in patients with lymphedema (LE), lipedema, and lipolymphedema. Methods and Results: Eighty-one patients who were consulted for physiotherapy, whose diagnoses were LE, lipedema, and lipolymphedema, and who were treated or planned to be treated for these diagnoses, were included in this study. PBI-L was adapted to Turkish by considering the stages of the cultural adaptation process. Short Form-36 (SF-36) was applied for the validity of PBI-L. PBI-L was repeated after a 1-week interval for test-retest reliability. The mean age was 47.66 ± 14.23 years. The intraclass correlation coefficient (ICC) value was determined as 0.73 (p < 0.0001) for the total score. There was a moderate correlation between first (ICC = 0.63, p < 0.0001) and second subdimensions (ICC = 0.62, p < 0.0001). Cronbach's α values ranged between 0.83 and 0.89. Low correlations were found between total scores of PBI-L and mental health, physical function subdimensions of SF-36 (p < 0.05). The Kaiser Meyer Olkin value was 0.6, and it was found that the PBI-L was not consistent with factor analysis. Conclusion: The Turkish version of PBI-L is a valid and reliable tool in patients with LE, lipedema, and lipolymphedema. However, the reassessment validity of PBI-L would be suggested by using an LE-specific quality of life questionnaire.

BACKGROUND:  Although lipedema is often clinically distinguished from lymphedema, there is considerable overlap between the two entities. The purpose of this study was to evaluate lymphoscintigraphic findings in patients with lipedema to better characterize lymphatic flow in this patient population. METHODS:  Patients with lipedema receiving lymphoscintigraphy between January 2015 and October 2017 were included. Patient demographics, clinical characteristics, and lymphoscintigraphic findings were extracted. Klienhan's transport index (TI) was utilized to assess lymphatic flow in patient's lower extremities (LEs).Scores ranged from 0 to 45, with values > 10 denoting pathologic lymphatic transport. RESULTS:  A total of 19 total patients with lipedema underwent lymphoscintigraphic evaluation. Mean age was 54.8 years and mean body mass index was 35.9 kg/m(2). Severity of lipedema was classified as stage 1 in five patients (26.3%), stage 2 in four patients (21.1%), stage 3 in four patients (21.1%), and stage 4 in six patients (31.6%). The mean TI for all extremities was 12.5; 24 (63.2%) LEs had a pathologic TI, including 7 LEs with stage 1 (29.2%), 3 LEs with stage 2 (12.5%), 6 LEs with stage 3 (25.0%), and 8 LEs with stage 4 lipedema (33.3%). The mean TI was significantly greater for extremities with severe (stage 3/4) lipedema than those with mild or moderate (stage 1/2) lipedema (15.1 vs. 9.7, p = 0.049). Mean difference in TI scores between each LE for individual patients was 6.43 (standard deviation +7.96). CONCLUSION:  Our results suggest that patients with lipedema have impaired lymphatic transport, and more severe lipedema may be associated with greater lymphatic transport abnormalities.

BACKGROUND: Lipedema is a chronic, progressive disorder of subcutaneous adipose tissue that usually affects the lower extremities of women. Also known as "two-body syndrome," the fat accumulations in lipedema are unsightly and painful. The disorder is well-known in Europe but is largely unrecognized and underdiagnosed in the United States. OBJECTIVE: To hold the First International Consensus Conference on Lipedema with the purpose of reviewing current European guidelines and the literature regarding the long-term benefits that have been reported to occur after lymph-sparing liposuction for lipedema using tumescent local anesthesia. METHODS: International experts on liposuction for lipedema were convened as part of the First International Congress on Lipedema in Vienna, Austria, June 9 to 10, 2017. RESULTS: Multiple studies from Germany have reported long-term benefits for as long as 8 years after liposuction for lipedema using tumescent local anesthesia. CONCLUSION: Lymph-sparing liposuction using tumescent local anesthesia is currently the only effective treatment for lipedema.

Purpose: Upper limb lymphedema is a vexing morbidity that can occur after the treatment for breast cancer. The Lymphedema Functioning, Disability and Health Questionnaire for Upper Limb Lymphedema (Lymph-ICF-UL) is a valid and reliable tool assessing problems in functioning in patients with breast cancer-related lymphedema. Until now, a French-language version was lacking. The aim of this study was to perform a cross-cultural validation of the French version of the Lymph-ICF-UL questionnaire.Methods: A forward-backward translation process between the original language (Dutch) and the target language (French) was performed. Psychometric properties of this final French version were examined in 50 participants.Results: Intraclass correlation coefficients for test-retest reliability ranged from 0.66 to 0.95. Cronbach's alpha coefficients for internal consistency were higher than 0.77. Face and content validity were very good because the scoring system was clear for all participants (100%), questions were understandable (100%), and all complaints due to BCRL were mentioned by 78% of the participants. Construct validity was moderate. Convergent validity was established since 3 out of 5 expected domains of the Lymph-ICF-UL showed a moderate correlation with expected domains of the 36-item Short-Form Health Survey. There was satisfactory divergent validity as 6 out of 9 hypotheses assessing divergent validity were accepted.Conclusion: The French version of the Lymph-ICF-UL is a reliable and valid questionnaire and ready for use in clinical as well as in scientific practice.Implications for rehabilitationSince the introduction of more effective treatment modalities increasing the number of breast cancer survivors, the amount of patients dealing with lymphedema is rising likewise up to a pooled incidence rate of more than 16% of the women treated for breast cancer.The French version of the Lymph-ICF-UL is a reliable and valid questionnaire for assessing problems in functioning of patients with breast cancer-related lymphedema of the arm and/or hand.As the questionnaire provides patient information in the different domains of the International Classification of Functioning, Disability and Health, it facilitates evaluating the impact of breast cancer-related lymphedema on daily functioning.Based on the outcomes of the Lymph-ICF-UL treatment goals can be set, where after the questionnaire can be used to monitor long-term results of this treatment and self-care.

Lipedema is a clinical condition in which there is abnormal swelling of body parts which may be confused with lymphedema and obesity. Allen and Hines first coined this term in 1940. It commonly affects lower limbs in symmetrical pattern. However asymmetric lipedema cases are reported also. Women are commonly affected. Diagnosis is mostly clinical. Imaging has important role in diagnosis and differentiating from closely related differentials. Conservative and surgical treatment are usually recommended. It is often misdiagnosed due to lack of proper knowledge and investigated in an inappropriate way. Here, we report a 36–years–old woman presenting with unilateral thigh swelling for 1 year. She had localized lipedema of left thigh and was advised for consultation with plastic surgery department.

The growth and differentiation of adipose tissue-derived stem cells (ASCs) is stimulated and regulated by the adipose tissue (AT) microenvironment. In lipedema, both inflammation and hypoxia influence the expansion and differentiation of ASCs, resulting in hypertrophic adipocytes and deposition of collagen, a primary component of the extracellular matrix (ECM). The goal of this study was to characterize the adipogenic differentiation potential and assess the levels of expression of ECM-remodeling markers in 3D spheroids derived from ASCs isolated from both lipedema and healthy individuals. The data showed an increase in the expression of the adipogenic genes (ADIPOQ, LPL, PPAR-&gamma; and Glut4), a decrease in matrix metalloproteinases (MMP2, 9 and 11), with no significant changes in the expression of ECM markers (collagen and fibronectin), or integrin A5 in 3D differentiated lipedema spheroids as compared to healthy spheroids. In addition, no statistically significant changes in the levels of expression of inflammatory genes were detected in any of the samples. However, immunofluorescence staining showed a decrease in fibronectin and increase in laminin and Collagen VI expression in the 3D differentiated spheroids in both groups. The use of 3D ASC spheroids provide a functional model to study the cellular and molecular characteristics of lipedema AT.

Purpose: Although the exact prevalence of lipedema is unknown the number of women suffering from this condition is ever-growing. When treated conservatively, manual lymphatic drainage is regarded the gold standard. However, the rate of its effectiveness varies considerably with some women showing minimal to no improvement depending on severity of the disease and medical history. Methods: Thirty female patients diagnosed with lipedema stage 2-3 referred to physiotherapeutic treatment were randomly allocated to either six treatments of MLD or to six treatments of combined MLD and vibrotherapy treatment. Outcome parameters were the volume of lipedema at four locations of either the lower (n = 29) or the upper extremities (n = 1), as well as quality of life. Findings: A very large superiority of effectiveness was found for the combined treatment. Reduction of the sizes of lipedema varied between 1.1 < d < 3.2. These patients' quality of life was also considerably better (d = 1.0). Conclusions: Combining MLD with vibrotherapy treatment drastically enhances the effectiveness of treating lipedema.

Lipedema is a disease with high prevalence but low recognition. It is often misdiagnosed and underdiagnosed. Obesity and lymphoedema are the most common differential diagnoses and can also coexist in patient with lipedema. Its broad range of presentation and fat distribution types contribute to this confusion. It is likely that lipedema symptom variations and presentation forms are often associated with hormonal variations, chronic low-grade systemic inflammation, and wide polygenic variations. This paper presents a theory regarding the clinical evolution of lipedema clinical and its involvement with other diseases, suggesting a three-phase approach for treatment.

Abstract The four previous articles in this series addressed the myths and facts surrounding lipoedema. We have shown that there is no scientific evidence at all for the key statements made about lipoedema – which are published time and time again. The main result of this “misunderstanding” of lipoedema is a therapeutic concept that misses the mark. The patient’s real problems are overlooked. The national and especially the international response to the series, which can be read in both German and English, has been immense and has exceeded all our expectations. The numerous reactions to our articles make it clear that in other countries, too, the fallacies regarding lipoedema have led to an increasing discrepancy between the experience of healthcare workers and the perspective of patients and self-help groups, based on misinformation mostly generated by the medical profession. Parts 1 to 4 in this series of articles on the myths surrounding lipoedema have made it clear that we have to radically change the view of lipoedema that has been held for decades. Changing our perspective means getting away from the idea of “oedema in lipoedema” – and hence away from the dogma that decongestion is absolutely necessary – and towards the actual problems faced by our patients with lipoedema. Such a paradigm shift in a disease that has been described in the same way for decades cannot be left to individuals but must be put on a much broader footing. For this reason, the lead author of this series of articles invited renowned lipoedema experts from various European countries to discussions on the subject. Experts from seven different countries took part in the two European Lipoedema Forums, with the goal of establishing a consensus. The consensus reflects the experts’ shared view on the disease, having scrutinized the available literature, and having taken into account the many years of clinical practice with this particular patient group. Appropriate to the clinical complexity of lipoedema, participants from different specialties provided an interdisciplinary approach. Nearly all of the participants in the European Lipoedema Forum had already published work on lipoedema, had been involved in drawing up their national lipoedema guidelines, or were on the executive board of their respective specialty society. In this fifth and final part of our series on lipoedema, we will summarise the relevant findings of this consensus, emphasising the treatment of lipoedema as we now recommend it. As the next step, the actual consensus paper “European Best Practice of Lipoedema” will be issued as an international publication. Instead of looking at the treatment of oedema, the consensus paper will focus on treatment of the soft tissue pain, as well as the psychological vulnerability of patients with lipoedema. The relationship between pain perception and the patient’s mental health is recognised and dealt with specifically. The consensus also addresses the problem of self-acceptance, and this plays a prominent role in the new therapeutic concept. The treatment of obesity provides a further pillar of treatment. Obesity is recognised as being the most common comorbid condition by far and an important trigger of lipoedema. Bariatric surgery should therefore also be considered for patients with lipoedema who are morbidly obese. The expert group upgraded the importance of compression therapy and appropriate physical activity, as the demonstrated anti-inflammatory effects directly improve the patients’ symptoms. Patients will be provided with tools for personalised self-management in order to sustain sucessful treatment. Should conservative therapy fail to improve the symptoms, liposuction may be considered in strictly defined circumstances. The change in the view of lipoedema that we describe here brings the patients’ actual symptoms to the forefront. This approach allows us to focus on more comprehensive treatment that is not only more effective but also more sustainable than focusing on the removal of non-existent oedema. , Zusammenfassung Die Mythen und Fakten des Lipödems waren das Thema der vergangenen 4 Teile dieser Artikelserie. Wir konnten zeigen, dass für die zentralen – und immer wieder publizierten – Statements zum Lipödem keinerlei wissenschaftliche Evidenz vorliegt. Wesentliche Folge dieses „Fehlverständnisses“ der Erkrankung Lipödem ist ein Therapiekonzept, welches an den tatsächlichen Beschwerden der Patientinnen weitgehend vorbeigeht. Der nationale, aber vor allem auch der internationale Zuspruch, der auch in Englisch zu lesenden Reihe, war immens und übertraf all unsere Erwartungen. Die zahlreichen Reaktionen auf unsere Artikelserie machten eines deutlich: Auch in anderen Ländern führen die Stilblüten des Lipödems zu einer zunehmenden Diskrepanz zwischen den Erfahrungen der Behandler und der durch – meist ärztlich verursachten – Fehlinformation geleiteten Perspektive der Patientinnen und Selbsthilfegruppen. Die Teile 1 bis 4 der Artikelserie über die Mythen des Lipödems haben deutlich gemacht, dass wir diese seit Jahrzehnten tradierte Perspektive auf die Erkrankung Lipödem verändern müssen. Veränderung der Perspektive heißt: Weg vom „Ödem im Lipödem“, damit auch weg vom Dogma der notwendigen „Entstauung“ und hin zu den tatsächlichen Beschwerden unserer Lipödem-Patientinnen. Ein solcher Paradigmenwechsel eines seit Jahrzehnten auf immer gleiche Weise beschriebenen Krankheitsbildes kann nicht Aufgabe Einzelner sein, sondern muss auf breite Füße gestellt werden. Aus diesem Grund hat der ärztliche Erstautor dieser Artikelreihe renommierte Lipödem-Experten aus verschiedenen europäischen Ländern zu einer Diskussion über das Lipödem eingeladen. Ziel der beiden „European Lipoedema-Foren“, an denen Experten aus 7 Ländern teilnahmen, war die Erstellung eines Konsensus. Dieser Konsensus spiegelt unter Sichtung der zur Verfügung stehenden wissenschaftlichen Literatur – bei gleichzeitiger Berücksichtigung der jeweils langjährigen klinischen Arbeit mit diesen Patientinnen – die gemeinsame Sicht der beteiligten europäischen Experten auf diese Erkrankung wider. Der Komplexität des Krankheitsbildes Lipödem angemessen war auch die Struktur der Teilnehmer interdisziplinär. Nahezu alle Teilnehmer des European Lipoedema-Forum haben in der Vergangenheit entweder über das Lipödem publiziert bzw. an ihren nationalen Lipödem-Leitlinien mitgearbeitet oder sind in Vorständen ihrer Fachgesellschaften vertreten. In diesem fünften und letzten Teil unserer Artikelserie über das Lipödem sollen vorab die wesentlichen Ergebnisse dieses Konsensus kurz zusammengefasst werden, wobei der Fokus auf der empfohlenen Therapie des Lipödems liegt. Das eigentliche Konsensus-Papier, „European Best Practice of Lipoedema“, wird dann in einem zweiten Schritt im Rahmen einer internationalen Publikation veröffentlicht. Statt einer Ödem-Behandlung wird im Konsensus-Papier auf die Behandlung des Weichteilschmerzes ebenso fokussiert wie auf die psychische Vulnerabilität der Lipödem-Patientin. Zusammenhänge zwischen der Schmerzwahrnehmung und der psychischen Situation der Patientin werden anerkannt und gezielt behandelt. Hierbei wird auch das Problem der Selbstakzeptanz thematisiert und spielt im neuen Behandlungskonzept eine herausragende Rolle. Eine weitere Therapiesäule stellt die Adipositas-Behandlung dar. Adipositas wird somit als mit Abstand häufigste Begleiterkrankung – und wesentlicher Trigger – des Lipödems akzeptiert. Bei schwer adipösen Lipödem-Patientinnen sollte daher auch die bariatrische Operation erwogen werden. Kompressionstherapie und gezielte Bewegungsaktivität wurden von der Expertengruppe deutlich aufgewertet, da durch die nachgewiesenen antiinflammatorischen Effekte die Beschwerden der Patienten direkt verbessert werden. Durch ein individualisiertes Selbstmanagement werden den Patientinnen Tools mit an die Hand gegeben, die den Therapieerfolg nachhaltig stabilisieren. Sollte die konservative Therapie zu keiner relevanten Beschwerdebesserung führen, kann die Liposuktion unter Einhaltung klar definierter Vorgaben erwogen werden. Die hier beschriebene Veränderung der Perspektive auf das Lipödem stellt die tatsächlichen Beschwerden der Patientinnen in den Fokus. Dies ermöglicht eine umfassendere, damit bessere und auch nachhaltigere Behandlung als die Fokussierung auf ein nie nachgewiesenes Ödem und dessen Entstauung.

The metabolic consequences of obesity arise from local inflammation within expanding adipose tissue. In pre-clinical studies targeting various inflammatory factors, systemic metabolism can be improved through reduced adipose inflammation. Lymphatic vessels are a critical regulator of inflammation through roles in fluid and macromolecule transport and immune cell trafficking and immunomodulation. Lymphangiogenesis, the expansion of the lymphatic network, is often a necessary step in restoring tissue homeostasis. Using Adipo-VD mice, a model of adipocyte-specific, inducible overexpression of the potent lymphangiogenic factor vascular endothelial growth factor-D (VEGF-D), we previously identified that dense de novo adipose lymphatics reduced immune accumulation and improved glucose homeostasis in obesity. On chow diet, however, Adipo-VD mice demonstrated increased adipose tissue immune cells, fibrosis, and inflammation. Here, we characterize the time course of resident macrophage accumulation and lymphangiogenesis in male and female Adipo-VD mice fed chow and high fat diets, examining multiple adipose depots over 4 months. We find that macrophage infiltration occurs early, but resolves with concurrent lymphatic expansion that begins robustly after 1 month of VEGF-D overexpression in white adipose tissue. In obesity, female Adipo-VD mice exhibit reduced lymphangiogenesis and maintain a more glycolytic metabolism compared to Adipo-VD males and their littermates. Adipose lymphatic structures appear to expand by a lymphvasculogenic mechanism involving lymphatic endothelial cell proliferation and organization with a cell source we that failed to identify; hematopoietic cells afford minimal structural contribution. While a net positive effect occurs in Adipo-VD mice, adipose tissue lymphangiogenesis demonstrates a dichotomous, and time-dependent, inflammatory tissue remodeling response.

Lipomas are defined as a common subcutaneous tumor composed of adipose (fat) cells, often encapsulated by a thin layer of fibrous tissue.[1] In fact, these are the frequently encountered neoplasms by the clinicians. [2] Clinically, they often present in the body's cephalic part, specifically in the head, neck, shoulders, and backs of patients. However, they can less commonly be seen elsewhere, for example, the thighs. The tumors typically lie in the subcutaneous tissues of patients. The masses are often benign, and while the age of onset can vary. There is usually no reason for treatment. They pose no threat to the patient unless they are uncomfortable due to being located on joints or rapidly growing, which is uncommon, as the typical lipoma growth is slow. Lipomas can sometimes, though rare, be associated with certain disorders such as multiple hereditary lipomatosis, Gardner syndrome, adiposis dolorosa, and Madelung disease.[3] [4] Some unconventional forms of lipomas include the following: angiolipoma, chondroid lipoma, lipoblastoma, myolipoma, pleomorphic lipoma/spindle cell lipoma, intramuscular and intermuscular lipoma, lipomatosis of nerve, lipoma of the tendon sheath and joint, lipoma arborescens, multiple symmetric lipomatosis, diffuse lipomatosis, adiposis dolorosa, and hibernoma.

Purpose To quantify chemical exchange saturation transfer contrast in upper extremities of participants with lymphedema before and after standardized lymphatic mobilization therapy using correction procedures for B0 and B1 heterogeneity, and T1 relaxation. Methods Females with (n = 12) and without (n = 17) breast cancer treatment-related lymphedema (BCRL) matched for age and body mass index were scanned at 3.0T MRI. B1 efficiency and T1 were calculated in series with chemical exchange saturation transfer in bilateral axilla (B1 amplitude = 2µT, Δω = ±5.5 ppm, slices = 9, spatial resolution = 1.8 × 1.47 × 5.5 mm3). B1 dispersion measurements (B1 = 1-3 µT; increment = 0.5 µT) were performed in controls (n = 6 arms in 3 subjects). BCRL participants were scanned pre- and post-manual lymphatic drainage (MLD) therapy. Chemical exchange saturation transfer amide proton transfer (APT) and nuclear Overhauser effect (NOE) metrics corrected for B1 efficiency were calculated, including proton transfer ratio (PTR'), magnetization transfer ratio asymmetry , and apparent exchange-dependent relaxation (AREX'). Nonparametric tests were used to evaluate relationships between metrics in BCRL participants pre- versus post-MLD (two-sided P &lt; 0.05 required for significance). Results B1 dispersion experiments showed nonlinear dependence of Z-values on B1 efficiency in the upper extremities; PTR' showed &lt; 1% mean fractional difference between subject-specific and group-level correction procedures. PTR'APT significantly correlated with T1 (Spearman's rho = 0.57, P &lt; 0.001) and body mass index (Spearman's rho = −0.37, P = 0.029) in controls and with lymphedema stage (Spearman's rho = 0.48, P = 0.017) in BCRL participants. Following MLD therapy, PTR'APT significantly increased in the affected arm of BCRL participants (pre- vs. post-MLD: 0.41 ± 0.05 vs. 0.43 ± 0.03, P = 0.02), consistent with treatment effects from mobilized lymphatic fluid. Conclusion Chemical exchange saturation transfer metrics, following appropriate correction procedures, respond to lymphatic mobilization therapies and may have potential for evaluating treatments in participants with secondary lymphedema.

Lipedema is a chronic and progressive disease of adipose tissue caused by abnormal fat accumulation in subcutaneous tissue. Although there is no known cure for lipedema, possible complications can be prevented with conservative and surgical treatments. One of the conservative treatment options is physiotherapy and rehabilitation (PR). When the literature is examined, few studies focusing on the efficacy of PR were found for this patient group. The purpose of this review is to provide a better understanding of the effectiveness of PR applications by compiling existing studies. A bibliographic PubMed search was performed for published studies regarding PR in lipedema management in June 2019 including the last 58 years (1951-2019). Articles were chosen by reading the abstracts and subsequently data were analyzed by reading the entire text through full-text resources. A total of 15 studies met inclusion criteria. Results document how lipedema patients are benefited by PR and the effectiveness of different types of PR programs. The current review also showed that complex decongestive physiotherapy, gait training, hydrotherapy, aerobic exercise, and resistance exercise training each have value in the management of lipedema. The effects of PR for the treatment of lipedema are variable among studies, although overall PR seems to be effective in lipedema management. Although physiotherapy applications have a potentially important role in the management of lipedema, they should be used in combination with other treatment modalities. More studies with higher quality are needed to fully demonstrate the effect and efficacy of PR in lipedema patients.

Lipedema can cause chronic pain and increases patients’ risk for conditions such as lymphedema and venous disease. This author explores how lipedema affects the body, why its effects are disproportionate in the lower body, and how to diagnose and manage the condition.

Obesity is a leading cause of cardiovascular diseases and cancer. Body mass is regulated by the balance between energy uptake and energy expenditure. The etiology of obesity is determined by multiple factors including genetics, nutrient absorption, and inflammation. Lymphatic vasculature is starting to be appreciated as a critical modulator of metabolism and obesity. The primary function of lymphatic vasculature is to maintain interstitial fluid homeostasis. Lymphatic vessels absorb fluids that extravasate from blood vessels and return them to blood circulation. In addition, lymphatic vessels absorb digested lipids from the intestine and regulate inflammation. Hence, lymphatic vessels could be an exciting target for treating obesity. In this article, we will review our current understanding regarding the relationship between lymphatic vasculature and obesity, and highlight some open questions.
