Does Wegovy slow stomach emptying?
Yes. Wegovy (semaglutide) slows the rate at which food leaves the stomach, known as delayed gastric emptying, and this effect is part of how it helps people feel fuller for longer and eat less. The effect can also influence how quickly other medicines taken by mouth are absorbed, which is why clinicians may review timing or suitability of certain oral medicines.
UK clinical and NHS-related guidance notes this delayed emptying mainly occurs after meals and is most noticeable during the dose-escalation period when starting or increasing Wegovy. Because of delayed stomach emptying, UK peri-operative guidance highlights a potential aspiration risk under anaesthesia, so patients are often advised to follow local surgical instructions about holding GLP-1 medicines before procedures.
- Wegovy slows stomach emptying (delayed gastric emptying), contributing to feeling full for longer.
- This effect can change how fast oral medicines are absorbed, so doctors may adjust other treatments.
- The delay is most evident after meals and during early dose increases.
- UK sources acknowledge delayed gastric emptying as a class effect of GLP-1 medicines.
- Before surgery, guidance highlights aspiration risk; patients should follow local instructions about pausing treatment.
