PHILADELPHIA — Roux-en-Y gastric bypass (RYGB) produces maximal weight loss in patients with obesity compared with other surgical procedures and with weight loss drugs, according to a meta-analysis comparing the efficacy and safety of the different treatment options.
However, tirzepatide, a long-acting glucose-dependent insulinotropic polypeptide (GIP) receptor agonist and glucagon-like peptide-1 receptor agonist (GLP-1 RA), produces comparable weight loss and has a favorable safety profile, reported principal investigator Jena Velji-Ibrahim, MD, MSc, from Prisma Health–Upstate/University of South Carolina School of Medicine in Greenville.
In addition, there was “no significant difference in percentage total body weight loss between tirzepatide when comparing it to one-anastomosis gastric bypass (OAGB), as well as laparoscopic sleeve gastrectomy,” she said.
