Hi, my 8 year old son has a TSH of 5.9, which I understand is slightly raised. I took him to the doc because I felt he had some similar symptoms to those I had when I had Graves Disease (headaches, short temper, protruding eyes, hungry but weight loss). He also has extensive vitiligo (about 85%body surface) which I know increases the risk of thyroid disease. The doc has said to repeat the TSH in a month or so - I'm just wondering if he ought to have any other thyroid screening at the same time, particularly as blood tests are fairly traumatic for him. Any advice much appreciated!
In addition, given your history of Graves', it might be a good idea to test TSI (thyroid stimulation immunoglobulin).
Those will give you a much better idea of what's going on.

Your doctor might also suggest a thyroid ultrasound, which is totally painless and will point out physical features of the thyroid.
