Abstract Background A laparoscopic adjustable gastric band (LAGB) is used to enable individuals to lose weight. However, the long-term weight loss outcomes for individuals with a body mass index (BMI) ≥50 kg/m2 and/or age ≥50 years at time of banding remains debated. To date, data reported is largely from populations outside the United Kingdom (UK). Objectives To explore long-term weight loss outcomes based on an individual’s pre-LAGB age and BMI. Setting Data were collected from individuals in the UK attending a National Health Service Weight Loss Surgery Service. Method Data pertaining to weight were collected in a prospective 5 year study in the UK. Individuals were grouped according to pre-operative age and BMI prior to analysis. Results Data from 53 individuals were analyzed. Individuals aged ≤49 years weighed 142.7 ± 17.4 kg pre-operatively, whereas, individuals aged ≥50 years weighed 137.6 ± 19.4 kg. Over the 5 years post-LAGB, significant weight loss was achieved by the whole sample. Additionally, there was an interaction between weight loss and age/BMI group. The sample had a significant percentage total weight loss, and percentage excess weight loss between 6 months and 5 years post-LAGB. However, only individuals aged ≥50 years with a BMI ≥50 kg/m2 pre-operatively had a continual weight loss over the 5 years. Conclusion Individuals lost weight following LAGB, however, only individuals prior to banding with a BMI ≥50 kg/m2 and age ≥50 years appeared to continue to lose weight as time since banding increased compared to the other groups.
