Just wanted to say

Bizbee and

for you with the journey you have been on and the dx you have had.
I came to this thread as my DS has Crohn's. I cannot answer you re the nausea and lack of appetite specific to UC, but as UC and Crohn's are both IBD's, I would say this is quite common.
DS suffers with nausea and poor appetite most days.
The steroids should increase your appetite, but drug regimes can knock you around, and everyone's metabolism reacts differently.
Someone else here will hopefully be able to answer you more specifically in relation to UC and you other questions re blood enzymes, immune responses and azathiaprine.
