Previous studies addressing the changes in serum visfatin levels after bariatric surgery yielded conflicting results.
We measured serum visfatin levels in 41 morbidly obese women before bariatric surgery and after losing at least 15% of the initial weight, and analyzed the results taking into account the type of surgery, reproductive and diabetic status, among others. Body mass index, waist circumference, lipid profile, and insulin resistance determined by homeostasis model assessment (HOMA-IR) were also measured.
Patients lost 30.3 ± 6.1% of the initial body weight, and serum visfatin levels increased from 22.2 ± 20.9 to 32.2 ± 27.6 ng/ml (P = 0.031). A multiple regression model (R 2 = 0.314, F = 3.555, P = 0.017) including the percentage of weight loss, changes in waist circumference, HOMA-IR, high-density lipoprotein-cholesterol, and triglycerides (also expressed as percentage from baseline), the surgical procedure, time elapsed since surgery, and previous diabetic status as independent variables showed that weight loss (β = −0.670, P = 0.010), previous diabetic status (β = −0.330, P = 0.036), and change in waist circumference (β = 0.556, P = 0.031) were the main determinants of the percentual increase in serum visfatin levels observed after bariatric surgery.
Serum visfatin increased after bariatric surgery in relation to the amount of weight lost and to the changes in waist circumference, and this increase was higher in diabetic patients.
