Abstract

Among 34,396 adverse events related to obesity treatment, 8,844 digestive system adverse events were analyzed.

  • Tirzepatide showed fewer reported digestive system adverse events compared to semaglutide and liraglutide.
  • Semaglutide and liraglutide were strongly correlated with reports of non-lethal pancreatitis.
  • Bupropion-naltrexone had the highest percentage of digestive system adverse events, at 31.65%, with a significant signal for mouth and lips adverse events.
  • Orlistat demonstrated the highest association with gastrointestinal adverse events, as indicated by a reporting odds ratio of 3.30.
  • Phentermine-topiramate was linked to hepatobiliary adverse events, with a reporting odds ratio of 6.13, warranting further investigation.
