Abstract

BACKGROUND:

Smoking cessation had been typically associated with weight gain. So far, there are no reports documenting the relationship between weight loss after bariatric surgery and smoking habit. The objective of the study was to establish the relationship between weight loss and smoking habit in patients undergoing bariatric surgery and to analyze weight loss on severe smokers and on those patients who stopped smoking during the postoperative period.

METHODS:

All patients undergoing laparoscopic sleeve gastrectomy (LSG) with at least 2-year follow-up were included. Patients were divided into three groups: (A) smokers, (B) ex-smokers, and (C) non-smokers. Demographics and weight loss at 6, 12, and 24 months were analyzed. Smokers were subdivided for further analysis into the following: group A1: heavy smokers, group A2: non-heavy smokers, group A3: active smokers after surgery, and group A4: quitters after surgery. Chi-square test was used for statistics.

RESULTS:

One hundred eighty-four patients were included; group A: 62 patients, group B: 57 patients, and group C: 65 patients. Mean BMI was 34 ± 6, 31 ± 6, and 31 ± 6 kg/m2; mean %EWL was 63 ± 18, 76 ± 21, and 74 ± 22 % at 6, 12, and 24 months, respectively. The subgroup analysis showed the following composition: group A1: 19 patients, group A2: 43 patients, group A3: 42 patients, and group A4: 20 patients. Weight loss difference among groups and subgroups was statistically non-significant.

CONCLUSIONS:

Our study shows that weight loss evolution was independent from smoking habit. Neither smoking cessation during the postoperative period nor smoking severity could be related to weight loss after LSG.
