Gut Health, IBS & SIBO

The DAO enzyme clears histamine from the body. When DAO activity is low, histamine builds up and may trigger flushing, headaches, gut upset and skin reactions.

SIBO is bacterial overgrowth in the small intestine. How breath testing separates hydrogen from methane patterns, and why relapse is common without follow-up.

Akkermansia muciniphila feeds on gut mucus and may strengthen the gut barrier, calm inflammation and improve insulin sensitivity. What raises and lowers it.

Reduced microbiome diversity, a leaky gut barrier and LPS-driven immune activation appear repeatedly in ME/CFS research. How the gut may sustain fatigue.

Chronic hives that don’t settle on a low-histamine diet may involve histamine-producing gut bacteria and low DAO. Which testing finds the driver behind them.

Psychobiotics are probiotic strains studied for mood rather than digestion. Which strains have evidence, how they act on the gut-brain axis, and what they suit.

Oxalates bind calcium into crystals that may contribute to kidney stones, joint pain and bladder irritation. Who tends to react, and which foods are highest.

Hypochlorhydria means too little stomach acid, not too much. How it may block protein, iron and B12 absorption, the symptoms it causes, and how it is tested.

The gut and brain talk both ways via the vagus nerve, immune signals and microbial metabolites. How dysbiosis and SIBO may feed anxiety, and what settles it.
