New blood results need help to understand

Just had my results from Blue horizon and need help to understand what they mean?

Never had full bloods taken before like this current med T4 100mcg and T3 25mcg daily. All I have know for 5 years is under active thyroid.

Doctors comments here: The thyroid stimulating hormone (TSH) level is low. If you are already taking thyroxine, dose adjustment may be necessary - you should discuss this with your usual doctor. If you are not taking thyroxine, it would be wise to keep an eye on this level - either by reference to previous results if known or by checking TSH again in 6 months’ time or so. There is a possibility that hyperthyroidism (overactive thyroid gland) will develop if the TSH fails to rise (a low TSH implies excessive thyroxine production from the thyroid gland). The positive thyroid antibody result, increases the possibility of your having or ultimately developing autoimmune thyroid disease, such as Hashimoto's thyroiditis or Grave's disease.

The folate (folic acid) level is low. Folate is one of the B group of vitamins found in green vegetables in particular. The body's reserves of folate, unlike vitamin B12, are low and only sufficient for about four months. Causes of deficiency include reduced intake from the diet or from poor absorption through the gut; increased demand for folate (eg pregnancy) and side effects of some medication (eg methotrexate). Symptoms include fatigue, mild sensation changes and depression. Prolonged lack of folate results in megaloblastic anaemia (in which the red blood cells are characteristically large). Supplementation would be advisable - I advise you to discuss this result with your usual doctor.

It's really not worth getting the comments from the BH doctor on these tests. They're only common or garden GPs who know little about thyroid, and there comments must be really confusing for someone who doesn't know much about thyroid.

A low TSH does not mean that you are going to 'go hyper', not with low Frees like that. Your TSH is low because you are taking T3. And you could probably do with an increase in T3, because your FT3 is only just mid-range. But, it depends how you feel with these results.

And those high antibodies do not mean you will develop Hashi's (definitely not Grave's with those levels!), they mean you already have Hashi's.

Your Vit D, B12, folate and ferritin are all too low, I'm afraid.

Thanks. I feel ok apart from eating like a horse and hungry all the time which then means I overeat and get fatter.

When I was a child I had a over active thyroid, could never put on weight always anemic and having b12 injections but never had the thyroid treated with meds ...

I may try to persuade my GP to refer me to an endo. I self medicate with T3 which he knows about. If my other levels like vit d b etc are optimised will my T4 level raise and convert better?

I had a suspected anemia due to heavy periods which I have to take transxamic acid for.

Your high antibodies confirm the cause of your hypothyroidism is autoimmune thyroid disease also called Hashimoto's

Did you know this?

Hashimoto's affects the gut and leads to low stomach acid and then low vitamin levels. Low vitamin levels affect Thyroid hormone working

Poor gut function can lead leaky gut (literally holes in gut wall) this can cause food intolerances. Most common by far is gluten. Dairy is second most common.

According to Izabella Wentz the Thyroid Pharmacist approx 5% with Hashimoto's are coeliac, but over 80% find gluten free diet helps, sometimes significantly. Either due to direct gluten intolerance (no test available) or due to leaky gut and gluten causing molecular mimicry (see Amy Myers link)

Changing to a strictly gluten free diet may help reduce symptoms, help gut heal and slowly lower TPO antibodies

Ideally ask GP for coeliac blood test first

Your vitamins are too low.

Your folate is below range. Take this blood test result to GP .

Your B12 is also low, but GP unlikely to think it low

You really need testing for Pernicious Anaemia before starting B12 and folate supplements. But GP unlikely to agree

Supplementing a good quality daily vitamin B complex, one with folate in not folic acid, may be more beneficial

If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 3-5 days before any blood tests, as biotin can falsely affect test results

Vitamin D is not low enough for GP to prescribe, but you likely need level higher. Do you supplement any vitamin D?

Aiming to improve to at least 80nmol and around 100nmol may be better . Vitamin D mouth spray by Better You is good as avoids poor gut function. Suggest you supplement 1000iu for 2-3 months and retest. It's trial and error what dose each person needs. Once you Improve level, very likely you will need on going maintenance dose to keep it there. Retesting twice yearly via vitamindtest.org.uk
