no. Conventional doctors do not believe that candidiasis exists in otherwise healthy people. They are not looking for candida, they do not know what it looks like and you owuld not be able to see it. If you have ever passed any candida yousefl you will see it is translucent. When attached to the wall of the intestine you are likely not to see it at all, or the doctor might say it is mucous etc.
I have had colonscopies in my life, take a look at the Image Gallery , no body saw all that stuff. And even though my colonoscopies were years ago, I am sure i was full of it then too.
