Ive been on a gluten free diet now for 2 years just rcently Ive been getting on going oral thrush that will not go away ive been to the GUM Clinic sexual health as at the time I couldnt get a gp appointment. I was told just to take prescribed medicine which I didnt take as I know it has something to do with my diet. I try eat healthy ...3 meals a day...including dairy. My thrush shows up in the mornings and at night time. I have just ate some single cream with strawberrys then looked at my tounge and its now fluffy white covering and the sides of my mouth is nipping.? And I do feel kind of full bloated belly. Could I now be tolerant to Dairy?? I know I should go see gp but ask for which blood tests?
