Post op diarrhea

I’m assuming that post op diarrhea is normal due to the stages of eating . I just had a revision from band to rny on Thursday so I’m 6 days post op. I was just discharged Sunday . I’m on stage 1 of clear liquids still and protein. I’m gassy and every gas is watery stools and constant . I’m also on an antibiotic and the side effect could be the trots . I’m sure sugar alcohol had aggravated it too. I’m just worried about dehydration happening as I’m trying to stay hydrated . I did introduce a triple zero Greek yogurt today because I’m tolerating fluid fine just being slow as instructed . I have had waters, a premier protein shake , some broth, some high protein low sugar ice cream (Enlightened) so about 300 calories today . I’m probably extra gassy from the 3 net carb good for you ice cream but I was already pouring watery stools being just on clear fluids . I’m hoping that once other textures come back that this tapers off? Thursday they should start me level 2 since I ate Greek yogurt today as I consider it liquid once it goes in.
