Elspethmann, your sister's TSH is low-normal but her FT4 is very low in range which may indicate secondary hypothyroidism caused by pituitary dysfunction. Perhaps your sister's GP could order a TRH stimulation test to confirm or rule it out.

Thyroid-stimulating hormone (TSH)

See also separate Thyroid Function Tests article.

Thyrotrophin-releasing hormone (TRH) stimulation test:

A TRH test may be indicated if secondary hypothyroidism is suspected.

A small amount of TRH is given intravenously and then blood is taken for levels of TSH at several subsequent time points.

Patients with normal function of the hypothalamic-pituitary axis respond by increasing the levels of TSH following TRH injection. Patients with compromised HPA function may exhibit a delayed, blunted or absent response to TRH administration.

TRH stimulation test may be useful in the diagnosis of central hypothyroidism, especially if free T4 and/or TSH are low-normal.[5][6]

What happens if I have too much gonadotrophin-releasing hormone?

It is not known what the effects are of having too much gonadotrophin-releasing hormone. Extremely rarely, pituitary adenomas (tumours) can develop, which increase production of gonadotrophins leading to overproduction of testosterone or oestrogen.
