Summary

This trial aims to investigate if fasting before a medical procedure and switching to a specific diet can help reduce the risk of certain complications in patients taking certain medications. The study will also look at how fasting affects

Who is the study for?
This trial is for patients on GLP-1 receptor agonists who are scheduled for upper endoscopy. They're looking at whether a clear liquid diet (CLD) for 24 hours before the procedure can help reduce stomach contents and improve safety during anesthesia.
What is being tested?
The study tests if a clear liquid diet versus standard fasting protocols can lower residual gastric content in patients taking GLP-1 RA medications before receiving anesthesia. It also examines patient comfort, timing of gastric emptying, choice of anesthesia, and any adverse events.
What are the potential side effects?
Potential side effects may include increased thirst, hunger, anxiety due to prolonged fasting; nausea, vomiting, retching; abdominal bloating or pain; and variations in the effectiveness of preoperative measures.
