Is there anything I can do to increase or restore my child’s intestinal bacteria (microbiome) back to normal?

Unfortunately not. Our understanding of the loss of unique bacterial species over the last 100 years is still in its infancy. The vast majority of everyone on the planet is believed not to have the full range of bacteria our ancestors had 100 or more years ago.nnWhile the consumption of probiotics or fermented foods might lessen some digestive symptoms, they do not provide the specific bacteria required within the intestinal microbiome. Even if a particular probiotic contained a unique species that historically was part of our microbiome, swallowing the bacteria will not result in the bacteria becoming a permanent part of the microbiome. Usually, the probiotic species disappears once the probiotic stops. FMT (fecal microbiome transplant) can lead to an increase in species within the intestinal tract but only partially. The use of FMT does not prevent the development of bacterial overgrowth (SIBO), the primary pathological defect in autism and developmental disorders.
