I agree with slowsmile and we all likely have our own version of candida. I think we have similar symptoms but each of are organs are ailing in different ways when compared to one another. I believe I likely had SIBO, parasites, candida, and even a few more bugs such as strept, mono, etc. I know I had mono a few years ago for certain. I battled strept throughout my childhood and I doubt I ever defeated it fully.
Digestion involves many organs so everything along the way is messed up in my opinion, starting with the mouth all the way down to the colon.
