What is FMT?

What is FMT?

Faecal Microbiota Transplants are performed to repopulate a patient’s gut with healthy bacteria from a fully screened and tested donor. This is done by combining a donor stool with saline solution and placing it into the colon of the patient via a rectal enema.

Why is a healthy gut so important?

The gut houses your Enteric Nervous System, which consists over around 100 million nerve cells that line the gastrointestinal tract. The gut is also responsible for the function of your immune system and your digestive system. The bacteria in your gut affect hormone levels, immune response, toxin elimination, mental health, vitamin production and vitamin and mineral absorption. Having a well-functioning gut and the correct balance of good bacteria is essential to ensuring that the gut can perform these critical functions efficiently and effectively.

Symptoms of poor gut health

  • Gas and/or bloating
  • Constipation
  • Diarrhoea
  • Heartburn/Acid reflux
  • Food sensitivities
  • Nausea
  • Lack of energy/Fatigue

What can cause an imbalance of gut bacteria?

There are many lifestyle factors that can contribute to an unhealthy gut.

  • Overuse of antibiotics
  • Use of antibacterial cleansers, mouthwash and soap
  • Overuse of medications such as aspirin, laxatives, antacids and pain killers that increase the permeability of the gut
  • Pesticide and herbicide use
  • Drinking chlorinated water
  • Antidepressant and sleeping pills
  • Cholesterol lowering medication
  • Artificial food colouring
  • High carbohydrate diet
  • Trans fat intake
  • Exposure to chemicals and heavy metals
  • Being born by caesarean section and not being breastfed

History of FMT

Faecal transplants were performed as early as the 4th century in China to treat sever diarrhoea and food poisoning, and to treat rumen disorders in animals. In 1983 FMT was first used to effectively treat patients with C.Diff, and it has been growing in popularity as a treatment for gut related disorders ever since.
