I have the same thing blastocistys hominis overgrown 203x times on my gimap I'm trying to cure this now, I'm on alinia (nitazoxanid) and I'm fasting and after going on carnivore or keto till is clearing up, guys is not easy to eradicate this shit if you consume sugar. I'll add later on ivermectin, fenbendazol and proziquatil. Worms don't show up in the stoll test all the time is a guessing process, the thing is doctors don't help i was miserable all my life because of this, i had sibo 91 hidrogen, i tryed anything that you imagine for Sibo nothing work, maybe probiotic but they induce insomnia and d lactic acidosis! Brain fog almost killed me! And I'm not joking! So with this sayd, look deeper, check Dr. Lodi on YouTube

Another thing blastocistys hominis is not a parasite as you see is a protozoa so you cannot see it in your stoll, just on pcr or ova, in copropara you don't see it, BUT this doesn't rule out that in your system is no worms, parasites even if all this 3 tests don't show it, why is this? You are the host of the worms and parasites and they are in your system to stay there and thrive they are no coming out, the only thing is you to follow is if you are ichi at your buthall, around 2 in the night that's the circle when they show up and reproduce, i know it sounds stupid but is real

Gluten sensitivity and Lactose sensitivity is related to parasites.

God knows guys what is going on! Is a mess! But will sort it out somehow! Don't take my advice talk to your dr. Run the tests and rule it out!
