GLP-1 Drugs Show Surgery Benefits

Researchers found people taking GLP-1 receptor agonists before surgery had lower risks of serious heart attacks and infections.

“These findings are particularly interesting because glp-1 medications are best known for their metabolic benefits”

Study Details

The study analyzed data from 2,028,601 adults who had elective surgeries lasting over an hour between 2016 and 2024.

Key Findings

GLP-1 users had 11% lower odds of major cardiovascular events and 8% lower odds of postoperative infections compared to non-users.

Inflammatory Response

GLP-1 drugs may reduce inflammation around surgery, which could explain lower infection risks.

“She added that it was especially interesting to see the associations persist around the time of surgery, when surgery typically triggers a substantial inflammatory response.”

Anesthesia Concerns

Anesthesiologists worry GLP-1 drugs might cause stomach contents to remain during surgery, increasing aspiration risk.

“Tolan said one concern for anesthesiologists is that the drugs delay gastric emptying, potentially leaving residual stomach contents despite standard fasting and increasing the risk of aspiration during anesthesia.”

Current Guidance

U.S. medical guidelines recommend individualized decisions about GLP-1 use before surgery rather than routine withholding.

“Tolan said current u.s. guidance favors an individualized approach rather than routinely withholding glp-1 medications from every patient before surgery.”

Next Steps

Further research is needed to confirm if GLP-1 reduces risks and how best to balance benefits against aspiration risks.

“Further research is needed to establish whether the apparent benefits are causal and how best to balance them against aspiration risk, she added.”
