In this episode, I begin a comprehensive GI review series for the USMLE Step 1 based on First Aid. I utilize an integrated format along with clinical vignettes to describe a host of pathologies that are pertinent to everything from the stomach all the way to the mouth. I will spend more time on associated embryology in a follow up podcast. I spend time explaining pathophysiology where appropriate and do not just give you factoids. There are no attached slides.
