It's Candida Albicans, literally translated from Latin as "pure glowing white". It's typically a yeast in the body, but turns to a fungi when it reaches the bloodstream where it can infect the entire body (including the mouth). It's what causes thrush, and once you see it in the mouth, you can pretty much guarantee it's elsewhere. It's overgrowth is due to disbyosis, your gut flora out of balance, usually caused by antibiotic usage and excessive sugar intake (including refined carbs)
Do a search on candida, you'd be amazed at what it causes. The auto-immune story never sat well with me...the body is very intelligent, and if it acts as if it has an infection (elevated white blood cell count, inflammatory markers elevated) then it probably has an infection. Candida is SUPPOSE to be there, so it's ruled out. The problem is when it outnumbers the good bacteria.
Ive showed the doctors, but all they say is that my tongue is coated due to being sick. I have had this for months now and they don`t seem too worried. I was put on anti-fungal for a week but it diidn't do anything. I haven`t been on antibiotics for Crohn's, only for a prostate problem they thoughtt I had when this all started, then I got Cdifficile because of it and was put on antibiotics for that. During that time, my tongue went back to normal for a while, but came back after I stopped taking the antibiotics. I am now on Entocort but when I finish, I will be taking probiotics to try and restore the balance of bacteria and hopefully it will also take care of the white togue.
Yes, it is probably thrush. I got it when they gave me antibiotics for my Crohn's. The antibiotics kill off the good bacteria in your mouth and thrush is a fungus. It is easy to treat with prescription lozenges, but it takes a couple of weeks for it to go away. It won't go away on its own, so you need to go to the doctor. Good luck!
