I had an edoscopy and colonostomy several years ago due to all the discomfort I was suffering from. All the colonostomy
showed was no polyps. I dont believe either one would show the minscule holes that candida would produce in intestinal
lining which in my opinion would be microscopic in size.
Im not sure there is a test for that. Best thing Im told is
probiotics, diet, collostrum, aloe vera juice, and a few other supplements Ive heard of.
