Hi I have a daughter who is 12 years old, the symptoms she is showing consist of diarrhea, extreme fatigue (probably from the emptying of her fluids,she has vomited 3 times in a period of 2-3 hours, and she has an on and off mild fever. Lastly she has a persistent upset stomach. She is drinking pedialyte and is resting. The symptoms that are staying the most are diarrhea, extreme fatigue, and the upset stomach. I was wondering maybe you could give me suggestions or tell me what you might think it is. ~Thank you.
