I wanted to ask you about bacterial overgrowth I don't understand why they put NP. IMO they are already a problem. I have also HP and Klebsiella and stuff. They create enough damage in the gut as you guessed. Unfortunately rx Antibiotics did not work for me neither for HP nor other bacteria. Guess was too chronic. One friend benefit from Antibiotics with HP but got a beautiful dysbioisis after in the gut...who knows
From what I have read and experienced SIBO could create these problems either directly by toxins either by inflammation either by leaky gut effects. including HP. I would be careful with supplements also as some cam create more problems if not well targeted. Ex: bacteria from ecoli group are acidic lovers and fructose lovers and diary lovers. I got recurrent UTI by taking cranberry juice which is not always ok with ecoli group.
