High ghrelin concentration is not a predictor of less weight loss in morbidly obese women treated with laparoscopic adjustable gastric banding

Abstract

Background: We analyzed the role of high plasma ghrelin concentrations at surgery as a negative predictor of weight loss in morbidly obese patients treated with laparoscopic gastric banding (LAGB).

Methods: Fasting plasma ghrelin concentrations were measured in 113 women before LAGB, and 16 of them were identified as having ghrelin concentrations clearly higher than expected according to the BMI levels. The 2-year postoperative outcome of these 16 patients was compared to the outcome of the remaining subjects.

Results: Mean fasting plasma ghrelin concentration in the group with hyperghrelinemia was 82.3+/-23.1 pg/ml and in women with normal ghrelin was 27.1+/-11.3 pg/ml (P<0.001). No differences in age, age at onset of obesity or degree of obesity were observed between the two groups. Women with hyperghrelinemia had a weight gain during the waiting time similar to women with normal ghrelin. The prevalence of comorbidities and eating behavior disturbances was similar in the two groups, but depression was 2.5 fold more prevalent in the hyperghrelinemic women than in the women with normal ghrelin. The %EWL after LAGB surgery was similar in women with high and normal ghrelin concentrations, with no differences in levels of postoperative band filling. No differences in band-related complications or revisional surgery rate were observed between the two groups.

Conclusion: A high fasting ghrelin concentration at baseline did not significantly affect the outcome after LAGB in morbidly obese women, in terms of weight loss and complications rate.
