Eosinophils at 30!!

  My wife has been suffering from chronic diarrhea and vomiting for three weeks. She has been hopitalized due to severe dehydration twice and has been given nutrition intravenously. She has had multiple CBCs, Colonoscopy, EGD ( scope inserted down the throat) and Barium Pass Through tests. She has supplied at least ten stool samples that have been tested for bacterial and parasitic traces. She has lost about ten pounds of wieght. She continues to have abdominal cramps, nausea and diarrhea after every attempt to eat. Bland diet or regular diet does not make a difference. The only abnormal results from these diagnostic measures has been a high eosinophil count (30), a visualized area of mild redness in the stomach and a slight melanomized area around the duodenum. The radioligists were surprised during the Barium Pass Through test that the compound moved through her small intestine extremely rapidly. The only slight relief that she has been able to achieve from the diarrhea is while using a product called LoCholest. This product seems to reduce the amount of water lost through the colon as well as making the stool somewhat more binding. Our doctor wants her to next have an ultrasound image of her gall bladder and a fat absorbtion test. He admits that he does not know what is causing the problem. Can you help? We know that high eosinophils can be a result of parasite infection and/or alergic (allergic) reactions. When the stool is tested for parasites, is it only tested for certain ones or all types? Where do we go next?
