I am sorry and in the past we have some members diagnosed as psychotic and put in mental hospitals.
At the age of 17 (or any age) when mental conditions are due to the lack of thyroid hormones it is scandalous - no other word. The inability of the medical profession to know clinical symptoms and the reliance upon the TSH only needs to be rectified for what appears to be a very common illness, even more common if diagnosed properly.
Due to non-diagnosis hundreds of people have on their medical records mental health conditions which cannot be removed and which were actually undiagnosed dysfunctions of the thyroid gland. Those we expect to tell us what is wrong it doesn't even cross their minds.
No-one does or thinks that the person in front of them may desperately require hormone replacements.
