Sedative exams like endoscopy may require prolonged fasting for semaglutide users

D'Or Institute for Research and Education

A recent study published in the Journal of Clinical Anesthesia investigated the relationship between semaglutide use and residual gastric content in patients undergoing upper gastrointestinal endoscopy (EGD). Conducted by researchers at the D'Or Institute for Research and Education (IDOR), the retrospective study analyzed medical records of 404 patients to assess the risks associated with semaglutide use, a glucagon-like peptide-1 (GLP-1) receptor agonist, in anesthetic procedures. The findings highlight the importance of revisiting preoperative fasting guidelines for patients on GLP-1 analogs to ensure the safety and efficacy of endoscopic procedures.

By analyzing samples from obese non-diabetics, researchers from the State University of Campinas found that high blood levels of saturated fatty acids cause pre-activation of innate immune cells that, when infected with SARS-CoV-2, produce elevated levels of inflammatory molecules. Results were presented during FAPESP Week China.
