Question

Does yeast infection in the GI system cause irritable syndrome? How can a person get rid of yeast in the GI tract?

Answer 1

Hmm, careful here...
Don't take this as the New Gospel, as I am not a doctor...

Explanation:

I guess we are discussing Candida(Albicans)...

Yes, it CAN, but doesn't necessarily, cause IBS.
Abnormal proliferation of Candida can lead to an upset of the intestinal flora (Dysbiosis), resulting in IBS.

Treatment: a good antifungal, usually Nystatin or Clotrimazole ...

PS: If you are a sufferer, go and see your GP.
