What Disease Did King Viserys Dying From?

Hey everyone welcome back. So today I wanted to take a look at the House of the Dragon series with a particular focus on King Viserys and what is actually going on with his health because it’s been an identifiable focal point despite the overall darker theme of the story focusing on the pending war between the Targaryens. There's not a single episode that doesn’t highlight the kings declining health and I want to take a look at those issues today and actually come to what I hope will be a solid conclusion on what exactly is happening to viserys.
