BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) is a common surgical treatment for obesity. Evidence for and against the association of aerobic exercise (AE) and weight loss after LAGB exists. We hypothesize that aerobic exercise is associated with improved weight loss and resolution of comorbidities after LAGB. METHODS: A review of a prospectively collected database identified patients who underwent LAGB over a 3-year period at a single institution. Body mass index (BMI), comorbidities, frequency, and duration of exercise were collected preoperatively and at 6, 12, 24, and 36 months postoperatively. Excess weight loss (EWL) was calculated. Groups were analyzed using Fisher's exact test and ANOVA. RESULTS: Of the 145 LAGB patients, 120 had adequate data for analysis. AE had no association with weight loss at 6 months. At 12, 24, and 36 months following LAGB, patients who reported 150 min or more per week of exercise had an EWL of 35.5, 47.3, and 54.1 %, respectively, while those reporting 0-59 min per week of AE had an EWL of 25.3, 32.1, and 33.0 % (p = 0.03, 0.03, and 0.02, respectively). BMI and age was not statistically different among groups. Diabetes and obstructive sleep apnea were significantly improved in patients exercising at least 60 min per week as compared to those exercising 0-59 min. CONCLUSIONS: AE is significantly associated with weight loss and comorbidity resolution after LAGB. We propose that patients who perform more AE will have higher levels of EWL.
