In a new statement, five professional gastroenterology organizations caution that there are currently no data to support stopping glucagonlike peptide 1 (GLP-1) receptor agonists prior to elective endoscopy
The medications, which include semaglutide (Ozempic, Wegovy), tirzepatide (Mounjaro), and liraglutide (Saxenda), among others, are used for the treatment of diabetes or for weight loss and may be associated with delayed gastric emptying.
Patients taking GLP-1 receptor agonists for diabetes management “need to be cautious about withholding these medications because doing so can adversely impact blood glucose control,” said Octavia Pickett-Blakely, MD, a gastroenterologist with University of Pennsylvania in Philadelphia and spokesperson for the American Gastroenterological Association (AGA). “In patients undergoing endoscopic procedures, poorly controlled blood glucose could raise the risk of complications.”
In a commentary on Medscape, David Johnson, MD, professor of medicine and chief of gastroenterology at Eastern Virginia Medical School in Norfolk, urges clinicians to learn about the topic and inform patients when prescribing GLP-1 receptor agonists.
“These are new and changing issues. In our world as gastroenterologists, we should be considering – very strongly – mitigating strategies to protect the patients on this wonderful class of therapy,” he says. “Sometimes these drugs can have significant side effects that we need to at least be aware of. Nothing is perfect, but let us be better informed.”
“We really don’t know what the risks are yet. With endoscopy, they could be significant, but perhaps they’re not,” Jonathan Leighton, MD, a gastroenterologist with Mayo Clinic Arizona in Phoenix and president-elect of the American College of Gastroenterology (ACG), told this news organization. “There are a lot of factors that go into this, and we just want to proceed cautiously and carefully until we know more.”
The ACG, AGA, the American Association for the Study of Liver Diseases, the American Society for Gastrointestinal Endoscopy, and the North American Society for Pediatric Gastroenterology, Hepatology & Nutrition released the statement on Aug. 11.
It was issued in response to recent guidance on the preoperative management of adults and children on GLP-1 receptor agonists put forth by the American Society of Anesthesiologists.
In a separate statement, the AGA stated that there is little, or no data on complications from aspiration.
“While there is anecdotal experience that increased gastroparesis risk may be dose dependent or related to whether it is being used for diabetes control versus weight loss, we also acknowledge that there is little, or no data related to the relative risk of complications from aspiration. As a result, the impact associated with stopping these therapies prior to undergoing upper GI endoscopy (EGD) or other moderate to deep sedated procedures is unknown at this time.
“As clinical gastroenterologists and hepatologists, we are very familiar with safety issues regarding the performance of endoscopy in our patients suffering from gastroparesis as well as unexplained nausea, vomiting, and epigastric pain, particularly in emergency situations. As patient safety will always be paramount, and in the absence of actionable data, we encourage our members to exercise best practices when performing endoscopy on these patients who are taking GLP-1 receptor agonists. More data are needed to understand if and when these medications should be held prior to elective endoscopy. Given the need for further data regarding the emerging use of these novel compounds, we encourage our anesthesiology, endocrinology, and industry partners to work collaboratively with our members to develop the necessary evidence to appropriately inform medication adjustments prior to elective endoscopy.”
