eGFR (estimated glomerular filtration rate)
What a GLP-1 receptor agonist actually does: which receptors it reaches, how it slows gastric emptying, and the satiety pathway it runs through.
What is eGFR (estimated glomerular filtration rate)?
Estimated glomerular filtration rate, the standard read on kidney filtration, in mL/min/1.73m².
Normal sits at 90 or above. A level under 60 sustained across three months defines chronic kidney disease; stage 4 runs 15–29 and stage 5 falls below 15. In FLOW, semaglutide cut major kidney-disease events by 24% among people whose type 2 diabetes had already brought on chronic kidney disease (Perkovic 2024, PMID 38785209), and that result drove the 2025 Ozempic label expansion.
GLP Watchdog writes these definitions from FDA labels and peer-reviewed PubMed literature.
