This means that we're made up of more bacteria than our own cells! Most of them live in our gastrointestinal tract.

Typically by age three your microbiome resembled an adult’s, They play a crucial role in maintaining a healthy digestive system. Despite changing in response to events like illness, disease, antibiotic treatment, fever, stress, injury, your micro biome tends to shift back to a "baseline" state.

Thank you for the question.
