Abstract Due to the association between the quantity of adipose tissue and concentrations of interleukin-6 (IL-6) and tumor necrosis factor (TNF-alpha), this work aimed to assess the effects of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) procedures on serum IL-6 and TNF-alpha concentrations.This study evaluated serum IL-6 and TNF-alpha levels, as well as routine anthropometric and biochemical values, before and 1 year post-bariatric surgery. Fifty percent of patients (n = 24) underwent RYGB, and 50 % (n = 24) underwent SG. Prior to bariatric surgery, IL-6 and TNF-alpha mRNA expression levels in subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) were investigated in obese women.There was a significant reduction (p < 0.05) in all anthropometric and routine biochemical measurements in patients in the RYGB and SG groups 1 year post-surgery. the serum concentrations of IL-6 and TNF-alpha were reduced following surgery in both groups (p < 0.05). No differences in the relative expression levels of IL-6 and TNF-alpha were found between SAT and VAT prior to bariatric surgery.RYGB and SG procedures demonstrated a similar impact on adipokine levels in women 1 year post-surgery. Both techniques may improve the course of chronic diseases and the state of inflammation associated with obesity.
