Hi, my grandchild has been sick for several weeks with vomiting diahreah,fever, she has been to dr several times. they treated her with an antibiotic and med for nausea, after a week she was not better, then they gave her something to regulate bowels, she has become lactose intolerate and has lost weight, she hardly urinates at all, she is strictly on pedilite, fatty foods, no dairy or juice. She has a fishy breath smell, yellow poop, and looks like she is malnourished. I am concerned that my daughters boyfriend may have exposed her to something poison, Noone will listen to me and I cannot prove anything. Please help. I am really concerned for my grand-daughter.
