What this Trial Is About
This study will enroll patients 18 years and older who are taking a GLP-1/GIP medication and 1) are scheduled for elective surgery and meet ASA fasting guidelines (nothing by mouth for at least 8 hours prior), or 2) scheduled elective colonoscopy and have been on a clear liquid diet for at least 24 hours prior. Participants will have a gastric ultrasound prior to surgery to measure any retained gastric contents. The purpose of this study is to determine if people taking GLP-1 receptor agonists and who fast normally are at an equal risk for having retained gastric contents after appropriately fasting for surgery, compared to patients who are on a liquid only diet for 24 hours prior to surgery.
