My name is***** and I am sorry to hear that Jada had a bout of pancreatitis. It sounds like she is on the mend, though.
I will try to address all of your questions-
-she likely won't drink much water for the next 24 hours. Remember, she's been on IVs so she is likely very well hydrated at this point and is not feeling thirsty.
-the fact that she is eating anything and is able to keep it down is a great sign! This also means that she will drink when she is ready.
-No BM is okay at this point as well. If she was vomiting and diarrhea from the pancreatitis, she emptied her intestines completely and it will take 2 to 3 days to build up enough feces to create a bowel movement.
-Hiding is also not a big surprise. If you can imagine how you would feel after spending 24 hours in the hospital, she is likely worried that someone is going to touch her or take her temperature or give her an injection. I would still drag her out because the medications she needs tonight are vital to her recovery, but then let her sleep where she is comfortable until morning.
-She may be sleepy for a few days as she recovers as well. Pancreatitis creates huge amounts of inflammation and this can really make them feel drained. As long as she is eating and drinking and not having vomiting or diarrhea, she is going to recover.
Does this help? What other questions do you have?
