Summary

This study looks at two ways to manage pain during weight-loss surgery (sleeve gastrectomy) in 70 adults. One group gets standard opioid painkillers, the other gets a mix of non-opioid drugs. The goal is to see if the opioid-free approach can reduce opioid use and still control pain well. Researchers will track pain scores and when patients first ask for extra pain relief.
