Abstract

Adipose tissue is a metabolically active tissue. The hypertrophic fat cells of obese patients produce increased quantities of leptin and tumor necrosis factor-α (TNF-α) and are less sensitive to insulin. This study aimed to determine whether aspirating large amounts of these subcutaneous fat cells by large-volume liposuction (LVL), could change the metabolic profile in 123 obese women. All the patients had a main central body fat distribution (waist–hip ratio, 0.91±0.01) and a body mass index of 32.8 ± 0.8 kg/m). They were studied for 90 days after LVL to determine their changes in insulin sensitivity, resting metabolic rate, serum adipocytokines, and inflammatory marker levels. During 3 months of follow-up evaluation, LVL resulted in a significantly improved insulin sensitivity, resting metabolic rate, serum adipocytokines, and inflammatory marker levels. Such parameters correlate with a decrease in fat mass and waist–hip ratio. Interestingly, no significant changes were seen between the first (21 days) and second (90 days) metabolic determinations after LVL. However, these findings, confirm other preliminary data published previously, and could change the actual role of LVL in the multidisciplinary treatment of obesity.
