Artificial feces is a concept explored in treating people with a life threatening gastrointestinal infection Clostridium difficile. This synthetic stool, created in a Robogut, consists of 33 different types of bacteria. The stool is referred to as RePOOPulate, and the idea is that all the healthy bacteria is transplanted into a patient which then wipes out the bad bacteria. These fecal transplantations are not FDA approved. What do you think of this concept? What natural products do you recommend to your patients to maintain their gut health?
