Yes I tested negative for CDiff twice, and also underwent a stool panel that ruled out Giardia and other pathogens. GI doc thinks it is SIBO because I initially respond to antibiotics (Flagyl) and then slide back to loose stools and diarrhea. A CT scan of my belly did not show abnormalities and a routine colonoscopy a year ago was normal. I have been plagued with this for nearly four months which is nothing compared to others here but have lost nearly twenty pounds and don’t know what to eat to heal my gut. The reason it was thought to have been CDiff initially was because this all coincided with me taking Clindymycin for another infection. But something is clearly wrong with me
