I don't know if I heard this right but did he actually say 45-50% of the GI tract is candida normally ? That doesn't sound right to me.
But yes I agree sIgA is extremely important and I have low levels. I'm also starting to investigate my thyroids/adrenal. I had a consult iwth Janie Bowthorpe last night actually and eager to get going.
I think many things will be important to get well - thyroid/adrenals, enemas for the candida in teh colon, antifungals from the top, correecting oxidative stress, heavy metals if applicable.
