Does bacterial overgrowth effect your taste buds?

One time when I was in the hospital with pancreatitis,I was not able to eat,and everything tasted like cardboard.It turns out,with all of the antibiotics they gave me,I developed thrush.It was a white coating on my tongue,and was easily remedied by using a tooth brush to brush the tongue.It was gone in about 2 to 3 days,and food tasted like...well food again.

I haven't thought about thrush in years...I used to get it as a kid, as you said, after a run of antibiotics...it is similar to what I feel...like there is a permanent coating on my tounge and I have a cheesy taste in my mouth (haven't eaten cheese in days or more) doesn't matter what I eat, I have the taste or smell both in my mouth and in my pouch output. Food tastes like, as you say, cardboard.
That is why I thought about bacterial overgrowth. Not sure if thrush is systemic or just in the mouth.
I usually get this way after a severe run of sugar overdose. Hopefully now that I have cut it out for the last 48hrs that it will get better. No med that I have heard of helps.
I will use the tounge scarping technique but I think that it is all through the gut.
Other than diet, any other ideas?
