I have had 5 stool sample tests and so far 4 of the 5 came back negative. Reasons for tests was loose stools consistently, and a new, consistent odor to the stool. I ve been tested for CDiff, Giaria (sp?) and other bacterial infections. Why the same odor of the stool? Recently have been taking a probiotic, but it has been at least 12 weeks since starting it, and still loose stools and smell. Is my body just releasing the toxins I ve accumulated?
