Yep- I get that yellow bile output too on an empty stomach. In fact, it is the reason I really can't change my pouch first thing when I get up. Way too liquidy if my stoma starts to act up. I change my pouch when I get home from work because at least if my stoma starts to spew it is thick and easy to deal with instead of that liquid yellow stuff.
