I haven't been on here for a while as I finally got my symptoms taken seriously and Levo prescribed. However I've recently gone downhill (TSH 1.7) and had the dose increased and thought I would just check what the NHS guidance now was. I found this... definitely new since I last looked.
'If an underactive thyroid is not treated
It's unlikely that you'd have many of the later symptoms of an underactive thyroid, because the condition is often identified before more serious symptoms appear.
Later symptoms of an underactive thyroid include:
a low-pitched and hoarse voice
a puffy-looking face
thinned or partly missing eyebrows
a slow heart rate
hearing loss
anaemia'
Unlikely????? I only got treatment because of my low heart rate and switched on cardiologist, and I now have moderate hearing loss and have to wear hearing aids! I'm glad that these symptoms are finally recognised but so angry that for years my thyroid tests always came back as 'normal' and I didn't know enough to question it.
