Several people have mentioned that corticosteroids (like advair) can cause yeast infections all over the body, in the mouth and throat as well. I did a google search - yeast infection thrush cure edu org (I included edu and org to make sure I came up with non-profit sites). Advair can cause thrush in the mouth. There are some simple tests to find out if you do have an infection and there is medication as well as changes in diet that can help. I've just started eating yogurt, garlic and fresh oregano and taking glucosamine and acidiphilus supplements every day. I avoid sugar and other foods that encourage yeast growth. I do feel better after a week, but I don't feel absolutely cured and will try something else if this doesn't work.
