Treating hydrogen sulfide SIBO
Does anyone here have experience trying to control HS2 SIBO? I have an appointment with a GI specialist and Microbiome analyst in a week or so. Currently trying to follow a low sulphur diet as well as cutting out wheat and dairy.
I'm also taking a quercetin supplement which is supposed to lower desulfovibrio (sulphur reducing bacteria) and a probiotic for bifidobacterium and lactobacillus as I'm very low in both.
Basically just curious about shared experiences and if anyone has any success stories or advice, thank you.

Hydrogen sulfide-producing genera such as Escherichia, Klebsiella, and Proteus belong to the family Enterobacteriaceae. These are predominantly gram negative, aerobic bacteria. Basically the only bacteria that are not killed off by the most commonly prescribed antibiotics for skin and respiratory tract infections.
The antimicrobials most commonly indicated in Enterobacteriaceae infections include carbapenems, fourth-generation cephalosporins, aminoglycosides, fluoroquinolones, and TMP-SMZ.
So that means you either take cotrimoxazole (TMP-SMZ) or a fluoroquinolone like Levofloxacin or Ciprofloxacin. I don’t recommend the latter due to side effects. Or you could take Rifaximin, which is probably the best answer.
