Lipedema, a chronic disease characterized by excessive fatty tissue deposition in the hips, buttocks, and lower legs, significantly negatively impacts the quality of life of those affected. This disease, which almost exclusively affects women, is often underdiagnosed, and confused with obesity. Diagnosis of lipedema is crucial for initial treatment and improvement of the patient's quality of life. Hormonal changes, inflammation, and tissue fibrosis play an essential role in the pathogenesis of lipedema. This article presents nutritional strategies that may bring relief to patients with lipedema. Nutritional intervention for lipedema patients could be an adjunct to traditional treatment, improving quality of life and reducing pain. However, these findings must be subjected to further research and clinical trials. The exact mechanism by which diet affects lipedema remains incompletely understood and, therefore, requires further study. However, this work provides hope and direction for future therapeutic approaches and research in treating lipedema.

The aim of this pilot study was to investigate the effects of defocused and radial shock wave therapy, mesotherapy, and kinesio taping on pain, circumferences of lower limbs, echographic/ elastosonographic pattern of subcutaneous adipose tissue (SAT), and quality of life in patients with lipedema. Fifteen women affected by lower limb lipedema in stage II were treated with shock wave therapy, mesotherapy, and kinesio taping on thighs and legs (eight sessions, twice a week). The primary outcome was pain, as assessed by Numeric Rating Scale (NRS). Secondary outcomes included the limb circumferences measurements, the SF-12 Health Survey for quality of life, the International Classification of Functioning (ICF) for disability, and echographic/ elastosonographic changes of SAT. Significant reductions of pain and circumference measurements were seen in patients at each follow up. This was associated with significant reduction of thickness, echographic pattern improvement, and increased elasticity of SAT, with consequent positive impact on the quality of life and disability reported by the patients. The results demonstrate improved clinical and functional ultrasound findings in patients affected by lipedema in the early stages of lower limbs, and this combination therapy needs to be investigated in larger populations at multiple centers to confirm the findings.

Enhancing our understanding of lymphatic anatomy from the microscopic to the anatomical scale is essential to discern how the structure and function of the lymphatic system interacts with different tissues and organs within the body and contributes to health and disease. The knowledge of molecular aspects of the lymphatic network is fundamental to understand the mechanisms of disease progression and prevention. Recent advances in mapping components of the lymphatic system using state of the art single cell technologies, the identification of novel biomarkers, new clinical imaging efforts, and computational tools which attempt to identify connections between these diverse technologies hold the potential to catalyze new strategies to address lymphatic diseases such as lymphedema and lipedema. This manuscript summarizes current knowledge of the lymphatic system and identifies prevailing challenges and opportunities to advance the field of lymphatic research as discussed by the experts in the workshop.

Often regarded as the forgotten second circulatory system, the lymphatic system is critical in working with the venous and arterial system to maintain fluid equilibrium, circulate cells and signaling molecules in the immune system, and transport fat molecules and nutrients. When there is an alteration in the flow of lymphatic fluid, lymphedema is the result, usually manifesting as significant swelling of a particular region of the body with protein-rich fluid accumulation in the interstitial spaces. The result of this disease ranges from psychological disturbance to significant disability and morbidity, even leading to aggressive malignancy. The prevalence of lymphedema is in the hundreds of millions worldwide; however, it is routinely under-diagnosed and under-recognized as a disease, especially in the United States. Treatment rates for lymphedema are variable, ranging from low rates of treatment in non-cancer etiologies, to high treatment rates seen in breast cancer related etiologies. Furthermore, treatment modalities are equally notorious for being unsuccessful, either as a result of non-compliance or lack of efficacious therapeutic techniques, or a combination of both. There is no cure for lymphedema and treatment mainly focuses on minimizing limb swelling, maintaining functionality, and preventative treatments to reduce complications.

Lipedema is usually thought of as a dis-ease of women. Potentially diagnostic comparative data is needed between patients with lip-edema and those with lower limb lymphedema (LLL). Since there is no gold standard to diagnose lipedema, some promising modalities such as Tissue Dielectric Constant (TDC) need to be investigated among patients with lipedema and lymphedema. This study was completed with a total of 26 patients (14 lipedema, 12 LLL). Local tissue water was assessed with Moisture MeterD compact (DelfinTech, Kuopio, Finland) according to the TDC method at 300 MHz within a 2.5 mm tissue penetration depth via the following reference points: Thigh, calf (20 cm upper and lower point of knee level, respectively), and malleoli (5 cm upper point of medial malleolus). Patients with LLL showed significantly higher TDC values and interlimb TDC ratios in all affected points and unaffected malleolus points compared to patients with lipedema. No significant difference was achieved between genders with LLL in all reference points. The area under the curve (AUC) for thigh, calf, and malleolus reference points were found as 0.851 (95%CI .678-1.00), 0.801 (95% CI 0.612-0.989) and 0.786 (95%CI 0.596-0.976), respectively. Patients with LLL showed significantly higher TDC values compared to patients with lipedema, these differences should be carefully interpreted in patients with bilateral LLL and those with lipo-lymphedema.

Lipedema is a relatively common, unrecognized connective tissue disorder. It affects about 11% of women across the globe. In lipedema, there is symmetrical abnormal deposition of fat especially in the lower extremities. Lipedema can be accompanied with pain, spider veins and easy bruising. Lipedema is rare in men. The disease is progressive in nature. Trigger points for lipedema appear to be puberty, pregnancy and menopause. The disease affects various aspects of the connective tissues like lymphatics, veins, skin, ligaments and even joints as it progresses. Oestrogen and progesterone abnormalities seem to have a role in the progression of the condition. Lipedema also appears to have a genetic predisposition. Lipedema is classified into 4 stages depending on the degree and type of abnormal fat deposition. The severe form can be confused with Dercum’s disease. Depending on the site of deposition of abnormal fat, lipedema is also classified into 5 different types. Lipedema is often confused to be obesity or lymphedema and treated accordingly. Treatments are based on the stages and types of lipedema. Lipedema is extremely difficult to manage with diet, exercises and bariatric surgery alone. All treatments are focused around improving the quality of life, improving physical abilities and appearances.
