Lipedema: Pathophysiology, Functional Limitations and Physical Activity Implications – A Narrative Review

Abstract

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 impair mobility and reduce quality of life.

Beyond its characteristic fat distribution, lipedema is increasingly recognized as a complex disorder involving adipose tissue dysfunction, vascular alterations, and impaired physical function. As symptoms progress, many individuals experience reduced physical activity, contributing to further mobility decline.

Exercise is important in conservative management, but evidence remains limited. This narrative review summarizes current knowledge on lipedema pathophysiology, its impact on physical activity, and the role of exercise in disease management.

A literature search was conducted in PubMed, Scopus, and Google Scholar using keywords: "lipedema," "physical activity," "exercise," "inflammation," and "functional limitations." Peer-reviewed studies on pathophysiology, clinical presentation, and exercise-based management were included.

Results: Lipedema involves abnormal fat accumulation, fibrosis, and ECM remodeling, distinguishing it from obesity and driving functional impairment [4,15]. Chronic low-grade inflammation and microvascular dysfunction contribute to pain and reduced mechanical load tolerance [3,4,10]. Pain and discomfort are primary barriers to physical activity, leading to deconditioning [10,24,33]. Low-impact exercise may improve outcomes, but data remain limited [4,10,24]. The literature supports an integrated model where adipose dysfunction, pain, and reduced activity negatively impact functional capacity in lipedema.
