Hi everyone, hi BrongFog Boy,
I also suspect the gut is central to how PFS develops. Hormones are central to how the body regulates the microbiome. And I have experienced profound changes when taking steps to change the microbiome, such as fasting, taking zinc, other medicines, etc.
The microbiome is difficult to change, since existing microbes reassert themselves. But in Australia some researchers working on autism found a way of changing microbiomes of autistic people by A) giving antibiotics and bowel cleanse B) giving a stomach acid suppressant and 2 months of fecal transport.
It led to long term improvements in autism symptoms (suggesting it succeeded in changing the microbiome).
Here is the study published in Nature: https://www.nature.com/articles/s41598-019-42183-0
And here is the abstract:
Long-term benefit of Microbiota Transfer Therapy on autism symptoms and gut microbiota

Abstract
Many studies have reported abnormal gut microbiota in individuals with Autism Spectrum Disorders (ASD), suggesting a link between gut microbiome and autism-like behaviors. Modifying the gut microbiome is a potential route to improve gastrointestinal (GI) and behavioral symptoms in children with ASD, and fecal microbiota transplant could transform the dysbiotic gut microbiome toward a healthy one by delivering a large number of commensal microbes from a healthy donor. We previously performed an open-label trial of Microbiota Transfer Therapy (MTT) that combined antibiotics, a bowel cleanse, a stomach-acid suppressant, and fecal microbiota transplant, and observed significant improvements in GI symptoms, autism-related symptoms, and gut microbiota. Here, we report on a follow-up with the same 18 participants two years after treatment was completed. Notably, most improvements in GI symptoms were maintained, and autism-related symptoms improved even more after the end of treatment. Important changes in gut microbiota at the end of treatment remained at follow-up, including significant increases in bacterial diversity and relative abundances of Bifidobacteria and Prevotella . Our observations demonstrate the long-term safety and efficacy of MTT as a potential therapy to treat children with ASD who have GI problems, and warrant a double-blind, placebo-controlled trial in the future.
