Lipedema Reframed: AFS Framework for Surgical and Transdisciplinary Management

Area of Science:

• Adipose biology and connective tissue pathology
• Vascular-lymphatic integrity and neuroimmune regulation
• Endocrine signaling in lipedema pathogenesis

Background:

• Lipedema historically misclassified, leading to delayed diagnosis and poor surgical results.
• Emerging evidence highlights lipedema as a systemic disorder.
• Introduction of Adipoconnective Fragility Syndrome (AFS) as a unifying clinical model.

Purpose of the Study:

• To integrate current evidence into a clinically actionable model for lipedema.
• To frame lipedema as a multisystem condition impacting surgical planning.
• To guide perioperative management strategies for lipedema.

Main Methods:

• Narrative literature review integrating diverse biological and clinical evidence.
• Focus on mechanisms with established clinical correlations in lipedema.
• Analysis of adipose biology, connective tissue pathology, and neurobiology.

Main Results:

• Lipedema tissue exhibits adipocyte hyperplasia, immune dysregulation, fibrosis, and abnormal sodium handling.
• Caveolar biology, particularly CAVEOLIN-1, is implicated in hormonal hypersensitivity and vascular changes.
• AFS framework explains resistance to weight loss, recurrence, and varied surgical outcomes.

Conclusions:

• Reframing lipedema as Adipoconnective Fragility Syndrome (AFS) enhances surgical decision-making.
• The AFS model promotes earlier diagnosis, better patient selection, and optimized perioperative care.
• AFS facilitates a precise, multidisciplinary, and mechanism-based approach to lipedema surgery.
