My 17 yo DS has been suffering from health problems for a while and the Dr instead of giving laxatives, suggesting we see about his ADD medication etc ran blood tests. His TSH is 5.8. They say it doesn't need any action yet and they will review in 6 months. This was passed on by admin staff, we didn't see a Dr for results. He has high functioning autism and ADD so it's hard to see the wood for the trees as it were with things like lethargy, poor cognitive function and digestive issues. No one has even suggested a thyroid issue until now. Anyone got any experience of this sort of thing?
