Introduction

Circumferential enlargement of the thighs and buttocks is a condition characterized by an abnormal increase in the size and volume around the entire circumference of the lower limbs and gluteal region. This presentation can result from multiple underlying causes ranging from excess adipose tissue accumulation to fluid retention or lymphatic dysfunction. The condition not only affects physical appearance but often leads to discomfort, mobility issues, skin complications, and psychological distress.

Given the complexity and variety of causes, circumferential thighs and buttocks require a nuanced, multidisciplinary approach for diagnosis and management. Advances in medical science and cosmetic surgery have expanded treatment possibilities, ranging from lifestyle modifications and conservative therapies to advanced surgical interventions.

This guide explores in detail the causes and risk factors, clinical signs, diagnosis, treatment modalities, prevention strategies, complications, and quality of life considerations related to circumferential thighs and buttocks.

Obesity is the most common cause of enlarged thighs and buttocks. It results from an imbalance between caloric intake and expenditure, causing excess fat to accumulate throughout the body. In many individuals, the lower body is the preferred site for fat deposition due to genetic and hormonal factors.

Subcutaneous Fat Deposits: Fat is stored beneath the skin in the thighs and buttocks, contributing to increased circumference.

Visceral Fat Impact: Though primarily abdominal, overall body fat influences regional fat distribution.

Lipedema is a chronic disorder characterized by symmetrical and disproportionate accumulation of fat predominantly in the lower extremities, including thighs and buttocks. It mostly affects women and is often misdiagnosed as simple obesity.

Clinical Features: Painful, nodular fat deposits, easy bruising, and tenderness.
