David Nalin

David R. Nalin (born April 22, 1941) is an American physiologist, and winner of the Pollin Prize for Pediatric Research and the Prince Mahidol Award. Nalin had the key insight that oral rehydration therapy (ORT) would work if the volume of solution patients drank matched the volume of their fluid losses, allowing drastic reduction or replacement of intravenous therapy for cholera. He led the trials that first demonstrated ORT works in cholera and, crucially, in other dehydrating diarrheal diseas
