Selenium and iodine testing

I have just been told by my gp that you cannot get your iodine and selenium tested on the NHS is this correct?

Also I had asked for leaky gut to be looked at. She told me she hadnt heard of It, then I mentioned it was strongly linked to hasimoto so she Googled it and said oh you don't need that and we dont test for it!

Shocking response from a doctor this was all over a phone call.

I have since asked for another doctor to look at my request but wanted your advise before I get a call back

Mary thanks

Different surgeries and health authorities have different agreements to what may be tested so if your practice won't test selenium and iodine you'll have to find somewhere to do it privately. You could see whether Blue Horizon or Geneva test them

Leaky gut is not a recognised medical condition so NHS won't test for it.

There is no cure for Hashimoto's which causes 90% of hypothyroidism. Treatment is for the low thyroid levels it causes. Many people have found that 100% gluten-free diet is helpful in reducing Hashi flares, symptoms and eventually antibodies.

dawnydawn1 It looks like some areas do iodine and selenium testing, a quick Google found this


My Surgery doesn't test for Selenium, although they will for Potassium and Magnesium.

I would suspect most GP's would be astonished at the suggestion Hashimoto's has anything remotely to do with the gut. I know mine was.

Current treatment just looks at the resulting low thyroid levels, not interested in root cause or links to nutrition.

For that we need functional medicine/functional nutritionist. Or wait 20 years for standard treatment hopefully to evolve.
