Yes I have, I have consulted two doctors, one said it was because his gut flora is not right and the other said get a sample and we will investigate further. Sadly the last mentioned doctor does not believe in candida overgrowth in the gut which is stupid when you think you can get a candida out break anywhere on the outside of the body and in the mouth. My private paediatrician does believe in it and has told me to reduce the amount of coconut oil I am giving him a day to 1 tsp a day but I am a little afraid now. This happened once before when he ate fats, it was chicken fat but I thought coconut would be o.k. because it is an oil and it has many health benefits. There is no doubt that many doctors have scratched their heads when it comes to my sons different health problems, they mostly say they are not qualified to deal with his autism problems. However, he is lucky enough to be under the best children's hospital in the U.K. in London but whether they can help him remains to be seen.
