Background: Tendency for consumption of highly palatable foods had been termed as “Hedonic Hunger”. We prospectively analyzed the influence of bariatric surgery on hedonic hunger in adolescent obese subjects compared to a control group of non-obese, healthy subjects.
Materials and methods: Fourty-four obese subjects who were submitted to bariatric surgery (either laparoscopic adjustable gastric banding-LAGB, or laparoscopic sleeve gastrectomy -LSG, or laparoscopic Roux-Y gastric Bypass-LRYGB) were included in the study. Thirty seven patients were submitted to LSG (51%), 4 to LAGB (6%) and 3 (4%) to LRYGB. In the same period 23 healthy control subjects were included. Hedonic hunger was assessed with the German version of the validated “Power of Food Scale” (PFS) questionnaire preoperatively as well as after 6 months later.
Results: Total body weight (BW) as well as BMI differed statistically significantly between the two groups in all measurements (P<0.001). Six months postoperatively patients had a statistically lower body weight compared to preoperatively (29.114 ±11.433, P<0.001)The initial aggregated PFS score was significantly higher in patients than in the control group (2.82 vs. 2.16, P<0.002). We found a significant reduction of aggregated PFS score and for all the three subdomains after surgery compared to preoperative values. The difference of the PFS scores (dPFS) before and after surgery among the 3 operative procedures performed was non-significant (F= 1.43, P<0.249). However the mean value of the dPFS was higher in the LSG group and this tendency was also seen when comparing the subdomain scores (dPFS1, dPFS2, and dPFS3). A significant correlation of BW and all PFS scores in the patients´ group was noticed.
Conclusion: Bariatric surgery leads to a reduction of hedonic hunger scores in obese patients. This effect could also expain or set a further mechanismus for weight reduction after surgery. Further studies are warranted in order to elucidate the exact mechanisms of this action.
