Euthyroid is the state of having normal thyroid gland function. Examples of a nonfunctioning thyroid gland may be hypothyroidism, hyperthyroidism, or thyroiditis.
"Euthyroid: The state of having normal thyroid gland function. As opposed to hyperthyroid (overactive thyroid) or hypothyroid (underactive thyroid). Last Editorial Review: 10/30/2013."
Hi Missmummy i thought that too but said euthyroidism and reference books i looked at talked about TSH looking normal but the not .. and thats where euthyroidism comes from.
Hello so sorry can't give any help on this one, but I am sure somebody on here can offer you some help and advice. Let us know how you are doing.take care and good luck 🍀😊 xxx
secondary allostasis of thyroid function in fetal life, starving and in critical illness
Euthyroid sick syndrome
Euthyroid sick syndrome (ESS), sick euthyroid syndrome (SES), thyroid allostasis in critical illness, tumours, uremia and starvation (TACITUS), non-thyroidal illness syndrome (NTIS) or low T3 low T4 syndrome is a state of adaptation or dysregulation of thyrotropic feedback control[1] where the levels of T3 and/or T4 are at unusual levels, but the thyroid gland does not appear to be dysfunctional.
This condition is often seen in starvation, critical illness or patients in intensive care unit. The most common hormone pattern in sick euthyroid syndrome is a low total and unbound T3 levels with normal T4 and TSH levels.
Causes of euthyroid sick syndrome include a number of acute and chronic conditions, including pneumonia, fasting, starvation, anorexia nervosa, sepsis, trauma, cardiopulmonary bypass, malignancy, stress, heart failure, hypothermia, myocardial infarction, chronic renal failure, cirrhosis, and diabetic ketoacidosis.[1]
Euthyroid sick syndrome (non-thyroidal illness syndrome) has been assumed closely related with a series of diseases, (such as inflammatory bowel disease).[2]
It just means that your test results fall within the reference range. But of course, that doesn't mean all is well. It depends on where in the range they fall and what symptoms you are experiencing.
As a diagnosed/tteated Hypothyroidism patient of over 40 years, I've learned from bitter experience that doctors know very little about how to treat Hypothyroidism, endocrinologists aren't much better as they mostly tend to specialise in diabetes. I've learned to interpret thyroid test results and know what else is important in the proper treatment of HypOthyroidism. I'm not so hot on HypERthyroidism
If you pop over to the thyroid forum on Health Unlocked with your results, you will get a lot of help.
The problem in this country is they rarely test your T3 so the results they do get may look in range (the range itself in the UK is contentious) and tell you all is okay. When in fact you could well have a problem with conversion of T4 to active T3 leaving you feeling very unwell.
You ask for a print out of your results, as is your legal entitlement under the Data Protection Act. The doctor won't tell you anything other than 'fine' or 'normal'.
Get your results for TSH, FT4 and FT3, also thyroid antibodies, Vit D, B12, Folate and Ferritin. Post them on the thyroid forum and they will interpret them for you. Lung doctor won't know much about interpreting thyroid tests other than to tell you if they are in range
Your B12 at 281is too low, anything under 500 can cause neurological problems, recommended level is very top of it's range, even 900-1000. It's not possible to comment on folate as there's no reference range, it should be at least half way through it's range. B12 and folate work together. You could supplement your B12 with sublingual methylcobalamin lozenges and when supplementing with B12 take a B Complex to balance all the B vits.
Vit D is good. Recommended is for total Vit D to be 100-150nmol/L.
If you are not diagnosed/treated hypothyroid then your TSH is in a good place, most healthy people have a TSH of about 2 or below.
FT4 without the reference range can't be interpreted, ranges differ from lab to lab, there is no universal range for thyroid tests. Most healthy people would have FT4 half way through range or above.
Platelets are within the reference range of approx 150-450 10*9/L
"In uk b12 only get treated when its 150 a think."
That's about right. They only care about being within the range. When the range is something like 150-770 how can 151 and 769 both be 'fine' or 'normal'. Same with ferritin, Vit D, TSH, FT3, FT4, etc. So you supplement yourself to optimal levels to help yourself be as well as possible.
As I said, euthyroid means 'normal' as in 'in range', so if your results come back anywhere within the range, even if it is by just 0.1 then you would be classed as euthyroid. This is where diagnosis and treatment of thyroid disease is so wrong and leaves people very ill, they are relying on numbers only not symptoms.
Are you saying you have symptoms that you think are connected with Hypothyroidism? Is this why you have had thyroid function tests?
Have you had Thyroid Peroxidase antibodies tested (rarely done)? Thyroglobulin antibodies ( almost never done on the NHS except maybe by a good endocrinologist)? Positive antibodies mean autoimmune thyroid disease and you can have this before it shows up in TSH, FT4 and FT3 tests.
Also, if you have low normal (in range) TSH along with low normal FT4 and FT3, then this can point to central/secondary hypothyroidism which is where the problem lies with the pituitary or the hypothalamus rather than the thyroid. This isn't very common so doctors either don't know about it or don't think about it.
What supplements did you try? We should only supplement if we've been tested and found to be deficient. Also, poor quality, cheap supplements (think Holland and Barrett, Boots or supermarket own brands) contain the cheapest and frequently the wrong form of ingredients with lots of unnecessary fillers etc that we could react to.
You need to give ranges for any results, it's not possible to interpret them without because there's no knowing if you are under or over range or where within range, it's all important.
Just had sputum results back still brewing Haemopilis bacteria oh goody 3rd round antibiotics and quoted Mycoplasm on CT scan ... the wonderful world of medical terminology eh !
Hi Jeff having read the reply posts I can see why you wished you had never asked. But I am glad of the info as I have never heard of it before only the usual Thyroid problems which my husband had and took tablets for. Thyroid imbalance can cause allsorts of symptoms. Enjoy your day
