Hello, my daughter has been sick since last Monday. She s been complaining of a bad stomach pain, vomiting, and having frequent bowel movements which isn t diarrhea. She hasn t eaten since Monday although i did get her a strawberry smoothie on Friday that she later threw up. She has lost 7lbs since last Monday, and the only thing she s keeping down is Gatorade, not even water. What could the problem be?
