Hi all, my son is 12 and came home from school in May and had a patch of hair that had just fell out, it was quite a large patch the size of a 50p. Worried I took him the doctors and they referred him to a specialist who we have not yet seen! I went back to the doctors and demanded blood tests which showed an very underactive thyroid, they did further tests that showed a raised level of antibodies in his blood. So he was referred again to a specialist but we aren't due to see the specialist till mid September. I am worried about my son, he is very underweight, not much of an appetite, all the symptoms of an under active thyroid. Am struggling to get my head round it and so is he without him actually saying anything! Any advice for me pls, or anyone parent been through a similar situation.
