Substack
gregorykatz.substack.com· irregular· Published 7 days ago

A practising physician writes a Substack for a general readership on what medical science and clinical experience actually mean for patients, covering AI in medicine, how to judge a good doctor, and GLP-1 weight-loss drugs. The excerpts mix personal clinical anecdotes with explanation of trial results and a reflective, opinionated voice.
