Gut microbiome and health
The microbiome, the collection of bacteria, fungi, and viruses that live in and on our bodies, is a component of our immune system. The microbiome is essential to the defense systems of our bodies.
We have approximately 100 trillion microbes — including bacteria, fungi, and viruses — primarily found in the gastrointestinal system and our skin and other body parts.
I have a new word for you: Dysbiosis. Dysbiosis is a change in the composition, diversity, or metabolites of the microbiome from a healthy pattern to one associated with a disease. Antibiotics can be a cause. The replacement of microorganisms (via fecal transplants) can be an effective management option for some problems such as inflammatory bowel disease and certain recurrent infections associated with antibiotic use.
What does this have to do with you?
