Hi, I' ve been having diarrhea for over a week. I lost 5 pounds. I am not dehydrated. No abdominal pain; no nausea or vomiting. Abdomen is soft and non distended. I alredy went to my doctor; lab results show a moderate white blood cells in th stool. No ova, cysts, or parasites seen, Negative for E.coli, salmonella or shigella. What do you think?? I am worried about the WBCs
