@drdavidhall: Do GLP-1s really cause blindness? 👀 There IS a signal involving a rare optic-nerve condition called NAION. But that’s very different from saying GLP-1s commonly make people blind. Absolute risk matters. Recent data suggest roughly 1 additional case per ~7,000 semaglutide-treated patients per year — and we still don’t have proof that the medication itself is the cause. Association ≠ causation. #GLP1 #Ozempic #Semaglutide #Wegovy #WeightLossTok
