Fecal Microbiota transplant (FMT) is making the news this week. It is where faeces are transplanted from a healthy person  into another bowel to help change the bacterial make-up; the microbiota. Yes, you read this correctly!
Why would you want to do this? It acts in the same way as a probiotic and although it sounds disgusting, it has been used very successfully in treating clostridium difficile (C. diff) infection. It also looks to be one way of treating inflammatory bowel diseases; Crohn’s disease and ulcerative colitis, since the causes of these may be from bacterial imbalance.
You may be wondering how the new microbiota get there? It is performed using nasogastric tubes, endoscopy, enema or colonoscopy. There are also ongoing trials on using carefully sealed capsules for oral administration. If the disease is in the small intestine, access through the mouth is favoured and if in the large bowel, access through the rectum is preferred.
There are some websites that show how you can try it yourself, although this could be very risky business. Faeces should be pre-screened for infectious diseases, or there is a risk of picking up more than you bargained for.
An excellent review published a few years ago, explaining the topic in more depth .
Have you tried diet and supplements first?
