Abstract

Objective: The use of glucagon-like peptide 1 receptor agonists has been associated with gastroparesis, but little is known about the risk of gastroparesis in those with obesity but without type 2 diabetes (T2D), and how that risk compares with other treatment modalities for obesity. This study aims to characterise the relationship between different treatment modalities for obesity and the risk of gastroparesis in a population without pre-existing T2D.

Methods: A retrospective cohort study using Merative MarketScan Research Databases of individuals with obesity who underwent treatment with semaglutide, bupropion-naltrexone or sleeve gastrectomy from 1 January 2018 to 31 December 2022. The incidence of gastroparesis diagnosis was evaluated using International Classification of Diseases, Version 10 codes. The risk of gastroparesis was compared between three intervention groups using Cox proportional hazards regression models.

Results: Of the 55 460 individuals included, 36 990 (66.7%) were treated with semaglutide, 7369 (13.3%) with bupropion-naltrexone and 11 101 (13.7%) with sleeve gastrectomy. Gastroparesis rates among those treated with semaglutide versus bupropion-naltrexone versus sleeve gastrectomy were 6.5 per 1000 person-years (PY) vs 2.1 per 1000 PY vs 1.1 per 1000 PY, respectively. After adjusting for baseline characteristics, individuals treated with semaglutide had a higher risk of gastroparesis than those treated with bupropion-naltrexone (adjusted HR 3.33, 95% CI 2.27, 4.98) and sleeve gastrectomy (adjusted HR 6.14, 95% CI 3.94, 9.57).

Conclusions: There is an increased incidence of gastroparesis among individuals with obesity without T2D who are using semaglutide as compared with bupropion-naltrexone and sleeve gastrectomy. Understanding these potential side effects, though rare, may help guide personalised treatment regimens.
