New research warns individuals scheduled for medical procedures to halt popular weight loss drugs like Ozempic and Wegovy prior to prevent aspiration pneumonia, a risk associated with these medications


RT’s Three Key Takeaways:

  1. Glucagon-like peptide-1 receptor agonists (GLP-1RAs), including medications like Ozempic and Wegovy used for diabetes and obesity, are linked to an increased risk of aspiration pneumonia following endoscopy, as per research from Cedars-Sinai.
  2. The study, published in Gastroenterology, analyzed data from nearly 1 million de-identified US patients who underwent upper or lower endoscopy procedures between January 2018 and December 2020, finding that patients prescribed GLP-1RA medications had a 33% higher chance of experiencing aspiration pneumonia compared to those who did not take these medications.
  3. Patients scheduled for procedures should communicate with their healthcare team in advance and consider halting GLP-1RA medications to avoid potential complications, researchers suggest.

New research from Cedars-Sinai suggests people who are scheduled for certain medical procedures should stop taking popular weight loss drugs in the days or weeks prior to avoid complications.

Investigators found glucagon-like peptide-1 receptor agonists (GLP-1RAs)—medications like Ozempic and Wegovy that are used to treat diabetes and obesity—are associated with an increased risk of aspiration pneumonia following endoscopy.

Obesity Drugs and Endoscopy Complications

Aspiration pneumonia is caused by inhaling foreign materials—including food in the stomach, or secretions from the mouth and nose—into the lungs. One way the new obesity medications work is by slowing digestion, so people feel full longer, causing them to eat less. This also means that food sits in the stomach longer. 

As a result, the stomach may not empty completely during the usual duration of fasting that is recommended ahead of a surgical procedure to decrease the risk of aspiration, explains the study’s corresponding author, Ali Rezaie, MD, medical director of the GI Motility Program and director of bioinformatics at the MAST Program at Cedars-Sinai, in a release.

“Aspiration during or after endoscopy can be devastating,” Rezaie says in a release. “If significant, it can lead to respiratory failure, ICU admission, and even death. Even mild cases may require close monitoring, respiratory support, and medications including antibiotics. It is important we take all possible precautions to prevent aspiration from occurring.” 

A Look at the Study

The study analyzed data from nearly 1 million de-identified US patients who underwent upper or lower endoscopy procedures between January 2018 and December 2020. Patients who were prescribed GLP-1RA medications had a 33% higher chance of experiencing aspiration pneumonia than those who did not take these medications before the procedure. 

This comparison also considered other variables that could influence the outcome to ensure a fair comparison between the two groups.

“When we apply this risk to the more than 20 million endoscopies that are performed in the US each year, there may actually be a large number of cases where aspiration could be avoided if the patient safely stops their GLP-1RA medication in advance,” Rezaie says in a release.

“The results of this study could change clinical practice,” says Yee Hui Yeo, MD, first author of the study and a clinical fellow in the Karsh Division of Gastroenterology and Hepatology at Cedars-Sinai, in a release. “Patients taking these medications who are scheduled to undergo a procedure should communicate with their healthcare team well in advance to avoid unnecessary and unwanted complications.”
