I recently got back my second set of thyroid function test blood results (previous set a week and a half before). The GP said that the numbers haven't changed except my TSH has raised slightly (which I expected as I had the blood test done earlier in the morning):
TSH - 3.5 (0.35-5.5)
T4 - 10.7 (11.5-22.7)
Antibody test also came back negative.
The GP was really dismissive of my concerns about secondary hypothyroidism and my symptoms, suggesting that my issue was diet-related and that I should get a repeat blood test in 3 months but that the issue would probably go away on it's own. As my T4 is only slightly below the reference range, she was suggesting that there's nothing wrong with my thyroid at all and that my symptoms (constipation, bloating, gas, fatigue, breathlessness, sensitivity to cold, dizziness, palpitations) are caused by my diet.
I just feel very lost and don't know what to do as if they won't find out what's wrong with me/won't even accept that anything is wrong with me, how can I get treatment and start feeling better?
(BTW - I'm not medicated on Levo or anything as I've only recently started having these issues (TFT was normal in 2019 with same level of TSH as above and normal T4) and I've tested negative for coeliac)
