FMT stands for Fecal Microbiota Transplant, which is ‘the process of restoring the bacteria commonly found in a healthy human gut’ (according to the Taymount clinic).
Or, to put it in plain English: implanting a healthy person’s stool (+ microbiome) into a sick person’s gut.
The reason I wanted to share this information is that I’ve had FMT myself and will be sharing my experience in the future.
