Hi. My DS got this GI bug. It started on Saturday night at 1am. He ran a fever and threw up for a couple of days, but then started with the stomach aches and diarrhea. It has been 5 days now. He is still having stomach aches and diarrhea every time he goes to the bathroom. Ketones are negative. When he was first diagnosed with D, there was a possibility he had Celiac. The GI doctor doesn't think he has it. We did have blood work repeated, but haven't gotten the results back yet. My mom gut is telling me something is wrong. Who do I call? My PCM, Endo, or GI doctor? He has missed school all week. I know viruses take a while, but usually symptoms lesson as time goes by, and his aren't. He is eating a little. He at breakfast and lunch today, but he didn't want dinner. We have been avoiding milk products because of the tummy aches. I'm at a loss. Does D make illnesses last longer? Thanks.
