The standard tests for worms (stool examination and PCR) are highly inaccurate as worms don't shed 24/7. You have to do multiple tests and it's expensive. The more accurate tests that can detect worm DNA are only carried out by functional medicine specialists, and these are not usually covered by insurance.
So basically they just gave up on worms and assume everyone has them.
Now they only treat symptoms when worm burden becomes a problem.
They call it "gut dysbiosis" or "leaky gut" or IBS or any other number of vague disorders. They will never mention worms. They are not allowed to say that word.
They are unbalanced "pathogens" in your microbiome, goy.
