The Microbial Metabolites That May Be Rewiring the Brain: The Hidden Link Between SIBO, IBS, MCAS, Autism, ADHD, Glutamate, and Catecholamine Dysfunction
HPHPA, hydrogen sulfide, D-lactate and ammonia are microbial metabolites that may pressure catecholamine regulation through dopamine β-hydroxylase, COMT and mitochondrial ATP. A case-anchored look at the hidden link between SIBO, IBS, MCAS, POTS, ADHD-like symptoms and autism-spectrum features — a metabolite-driven mechanism rather than a purely compositional dysbiosis.
