Unraveling lipedema: comprehensive insights and the path to future discoveries

Lipedema is a chronic disease characterized by the symmetrical accumulation of adipose tissue in the lower body, primarily affecting women. Despite being recognized for over 85 years, the pathophysiology, diagnosis, and treatment of lipedema remain complex and not fully understood. This review consolidates current knowledge, emphasizing histological, genetic, and hormonal factors, alongside diagnostic and therapeutic approaches. Histological studies highlight changes such as adipocyte hypertrophy, increased fibrosis, and vascular alterations like angiogenesis. Genetic studies suggest a strong familial component, with multiple loci potentially influencing disease onset, yet the condition remains polygenic and influenced by environmental factors. Hormonal influences, particularly estrogen, play a significant role in disease pathogenesis. Diagnostic imaging techniques like dual-energy X-ray absorptiometry (DXA), ultrasound (US), and magnetic resonance imaging (MRI) provide valuable insights but are not definitive. Therapeutic strategies, including diet, weight loss, and Complex Decongestive Therapy, offer symptom management but are not curative, with liposuction considered for severe cases where conservative methods fail. The condition's complexity stems from genetic, hormonal, and environmental influences, necessitating further research to improve diagnostic and treatment strategies. Integrating genetic and hormonal insights into clinical practice could enhance patient outcomes and quality of life, highlighting the need for continued exploration and understanding of lipedema.
