Abstract

Purpose

Weight regain after bariatric surgery occurs in up to a third of patients and reduces treatment-associated health benefits. The efficacy of glucagon-like peptide-1 receptor agonists (GLP1-RA) for treatment of type 2 diabetes mellitus and obesity is well established, but their role in the treatment of weight regain after bariatric surgery remains to be defined.

Materials and Methods

This was a single centre retrospective observational study conducted at a Swiss bariatric reference centre. Patients with 6 months of treatment with GLP1-RA, up until November 2021, due to weight regain after bariatric surgery were identified. Data on body weight and relevant clinical parameters were collected before and after 6 months of treatment with GLP1-RA. Data are presented as median (interquartile range).

Results

Fifty patients (82% female) were included. Before GLP1-RA treatment (liraglutide, n=29; semaglutide, n=21), weight and BMI were 90.5 kg (83.4, 107.9) and 34.0 kg/m2 (31.7, 38.7), respectively, with a post-bariatric weight regain of 15.1% (10.6, 22.8) of total body weight and 4.6 kg/m2 (3.3, 6.2). After 6 months of GLP1-RA treatment, a reduction in weight and BMI of 8.8% (5.2, 11.4) of total body weight and 2.9 kg/m2 (1.8, 4.0) was observed (P value <0.0001), corresponding to 67.4% (40.4, 92.2) of the weight regain. No serious adverse events were reported.

Conclusion

For patients experiencing weight regain after bariatric surgery, two-thirds of the weight regain can be safely lost with GLP1-RA, providing clinicians with a therapeutic option for this clinical challenge, and highlights the need for a large-scale randomized clinical trial.
