Diarrhea: Diarrhea persisting for 4 weeks warrants a fresh warm stool sample sent for culture to check for pathogenic bacteria & parasites. It may also be caused by irritable bowel syndrome, food intolerance (gluten,lactose,roughage like salads,fruits,veggies) or inflammatory bowel disease. See if you can identify food triggers. Consult a gastroenterologist for evaluation &treatment if symptoms persist.
