How reliable is the temperature test?

I am not on medication but have very high thyroid antibodies-not high enough to be considered for medication though apparently. I feel OK most of the time but have terrible mood swings, thinning hair, find it hard to lose weight, low libido, depression etc. I've never had to deal with anything like this before and am finding it pretty hard.

After reading up about the gluten/thyroid connection I decided to go gluten free and as I had a bit of a history of problems with dairy I gave that up too. That was back in September and apart from feeling a bit better gut-wise I feel no different. My temperature used to be around 34 but over Christmas it gradually increased to 36 which I was thrilled about, but since then it's gradually been dropping and is now 34 again. I am really starting to despair. How do I know if I'm doing the right thing? Obviously it's pointless going to my GP so I am really hoping someone can help. Thanks a lot x

Usually the body core temperature is a guide for thyroid problems. around 36 confirms this. I'm surprised you haven't mentioned feeling cold - as in - core temperature - circulation - not just a chill if the doors open. This is major in my symptoms, all came about in the last 2 years.

Sorry why is it obvious not to see a GP?



If you have antibodies plus symptoms. You should be on medication. This is an excerpt from Dr Toft, ex President of the British Thyroid Association and if you wish to give a copy to your GP email

The combination of a normal serum T4 and raised serum TSH is known as subclinical hypothyroidism. If measured, serum T3 will also be normal. Repeat the thyroid function tests in two or three months in case the abnormality represents a resolving thyroiditis.2

But if it persists then antibodies to thyroid peroxidase should be measured. If these are positive – indicative of underlying autoimmune thyroid disease – the patient should be considered to have the mildest form of hypothyroidism.

In the absence of symptoms some would simply recommend annual thyroid function tests until serum TSH is over 10mU/l or symptoms such as tiredness and weight gain develop. But a more pragmatic approach is to recognise that the thyroid failure is likely to become worse and try to nip things in the bud rather than risk loss to follow-up.

Treatment should be started with levothyroxine in a dose sufficient to restore serum TSH to the lower part of its reference range. Levothyroxine in a dose of 75-100µg daily will usually be enough.


This is an explanation of Basal Temperature test:-


Poppyrose-I don't feel the cold, quite the reverse in fact. Re the GP, I meant that if I went saying I didn't want any meds but would prefer to cure my symptoms by cutting out gluten I think I'd be shown the door!

Shaws-I was supposed to be recalled but the GP seems to have forgotten about me. To be honest I'm scared to go on medication. I haven't any really bad symptoms and am worried in case I rock the boat :-( .
