TSH 4.8, borderline raised - what to expect from follow up bloods?

[mintymellons]

Hi
I posted over in General Health but thought it might be an idea to post here too.
So, I had a full set of blood tests done a couple of weeks ago. They were done due to me having an unusual symptom of a burning throat/mouth which didn't respond to acid reducing medications. I've also been generally pretty run down over the last few months with recurring eye infections and vertigo/dizziness along with the above.
Anyway, blood results showed that my TSH was borderline high at 4.8. Unfortunately I don't have the range for it. All other results were normal.
Having done my own googling research, I discovered that hypothyroidism can have many symptoms though this particular one (burning mouth/throat) didn't come up specifically.
I'm due to get the bloods repeated in four weeks time, but I was wondering what will happen if they remain the same?
I feel generally okay in myself, fed up with the mouth/throat thing but no typical hypothyroid symptoms such as lethargy, weight gain etc...
I'd be interested to hear if anyone has experience of burning throat/mouth, especially if thyroid related.
I've been back to the GP today and have now been given anti fungal drops to try, so we'll see.

Did you get thyroid antibodies tested? Some autoimmune thyroid conditions present with yo yo’ing TSH levels.

A burning mouth usually fits in with vitamin B deficiency but it could also fit severe Vitamin D deficiency too. Have your levels been tested?

Hypothyroid woudl manifest itself in other ways as well as/instead of a burning mouth.

Have you been advised to take a B12 supplement? A B12 deficiency often begets sore mouth/tongue.

Teddybear45, I don't know if my antibodies were tested or Vit D. The GP said it was a full MOT blood test based on my main symptom along with the vertigo and general run down-ness.
Notatwork, yes that's what I thought re my symptoms, though it appears that something is going on with my thyroid. I haven't been advised to do anything (apart from use the anti fungal drops prescribed today).

I'm a GP, that is very borderline and there is no huge evidence that treating makes a difference, though in certain circumstances you should definitely be treated e.g. if pregnant or TTC. This isn't medical advice but for borderline subclinical hypothyroid (I'm assuming your T4 was normal) I would generally repeat in 8 weeks with antithyroid antibodies.

Thanks Redstapler.
Yes, my T4 was normal as far as I'm aware, just the TSH borderline raised.
I do have a mitral valve prolapse with moderate regurgitation so I don't know if that would have any impact on potential treatment?

Probably not but you'd have to check with your GP. I think this is an incidental finding rather than an answer to your symptoms (again this isn't individual medical advice if the GMC is watching!!)

I agree Redstar, a bit of a red herring which I've latched on to in desperation.
Thank you for your non-medical advice

I agree with @redstapler re the next lot of tests.

I would also suggest that you get your next bloods done fasting and as early in the morning as you can because of the circadian rhythm to TSH.

I'm not aware of any reason why TFTs need to be done fasting or at any particular time of day.

TSH is a pituitary hormone and has nothing to do with the thyroid.

@Lara53 TSH is thyroid stimulating hormone so it kind of does have something to do with the thyroid in that it is a key oart of thyroid metabolism. No one said it was made in the thyroid but it goes up if the thyroid is underactive
