Characteristics and Clinical Features of Patients with Lipedema in Saudi Arabia: A Cross-sectional Comprehensive Assessment.

Background: Lower limb swelling presents a diagnostic challenge with diverse causes, including well-known issues like venous insufficiency and lymphedema, and less-understood conditions like lipedema. Lipedema, involving abnormal fat accumulation in the lower extremities, is frequently misdiagnosed, posing challenges for affected individuals. This research aimed to report and analyze the clinical features of patients presenting with the complaint of lipedema.

Methods: A retrospective cross-sectional study was conducted in Saudi Arabia from April to November 2023, involving adult patients from a specialized clinic in lipedema and lymphedema management. Data were collected through clinical evaluation and a comprehensive data collection sheet.

Results: In a cohort of 115 female patients (mean age: 38.58), the most common age for disease onset was around 20-29 years. Physical examinations revealed symmetric enlargement (88%), collar sign (43%), orthostatic nonpitting edema (49%), and telangiectasia (64%). Varicose veins were present in 36%, Stemmer signs in 2%, and foot edema in 13%. Clinical diagnosis with lipedema occurred in 71%, with grade 2 (31%) as the most common severity and type 3 (47%) as the prevalent disease type.

Conclusions: The current study, the first of its kind in the Middle East and specifically in Saudi Arabia, emphasizes the urgency of increased awareness and intervention due to a high underdiagnosis rate in lipedema. The observed complexity in symptoms and correlations between severity, lymphatic impairment, and body mass index underscore lipedema's multifaceted nature. Future research should explore regional and cultural influences and conduct larger studies to validate and recognize various lipedema features.
