GLP-1s slow gastric emptying, and a standard pre-operative fast may not empty the stomach
Anaesthesia guidance exists because case reports described residual gastric contents after adequate fasting. It applies to compounded products too.
Pre-operative fasting rules assume a normal rate of gastric emptying. A GLP-1 deliberately slows it, which is part of how it works — and which breaks the assumption the rules are built on.
The specific failure mode with compounded products: a patient on a branded pen usually names it. A patient on a telehealth compounded preparation frequently says "a weight-loss shot" or nothing at all. It is the same molecule with the same effect.
One sentence covers it: "I take [drug] at [dose], [weekly or daily], last dose [date]." It applies to any procedure involving sedation. Detail: GLP-1s and surgery.
