Writing this once so I can stop repeating it across threads. It is about surgery and anaesthesia, and it is deliberately narrow — everything I am not confident about is marked as such.
What is actually established
This is the one where the stakes are high and the answer is simple: tell the anaesthetist. Delayed gastric emptying means a stomach that is not empty after a standard fast, and that is an aspiration risk under anaesthesia. Current guidance is broadly to hold weekly agents for about a week before an elective procedure and daily agents for a day, but the decision belongs to the anaesthetic team and they can only make it if they know.
The condition it depends on
Agreed. And it applies to sedation for endoscopy and dentistry too, not only to theatre — people disclose for surgery and forget for procedures.
What I am not sure about
What would genuinely help is knowing how long before a procedure people were told to hold, and whether the interval differs between the weekly and daily agents. I would rather have one careful answer than five confident ones.

Timing surgery and anaesthesia around surgery: my surgeon required me to stop GLP-1 agonists 2 weeks before my scheduled procedure due to aspiration risk from delayed gastric emptying.
If you have any upcoming surgeries or procedures requiring anesthesia, TELL YOUR SURGEON AND ANESTHESIOLOGIST that you're on a GLP-1. This is critical for safety.

This is where I part company with the consensus forming above. Guidance here is not settled and varies by institution, so quoting one society's interval as the rule is misleading. The invariant part is disclosure, not the number of days.

Important PSA about surgery and anaesthesia and anesthesia: GLP-1 agonists delay gastric emptying, which increases aspiration risk during procedures requiring sedation or general anesthesia.
Current ASA guidelines recommend stopping GLP-1 agonists 1 week before scheduled procedures. ALWAYS tell your surgical team you're on this medication. Don't let this get overlooked.

This is my experience too, for whatever a second data point is worth. I had assumed I was the exception until I read this.
