What Is TSH and What Are Normal TSH Levels?

What Is TSH and What Are Normal TSH Levels

[Last updated 9th November, 2017]

TSH is a hormone that controls thyroid gland activity.

It’s typically used as a marker of thyroid health, but what are normal TSH levels?

This article explores what your TSH levels should be and how it relates to hypothyroidism.

What is TSH?

What is TSH?TSH is a hormone that controls thyroid function. It stands for Thyroid Stimulating Hormone.

It is actually produced by the brain’s pituitary gland, but stimulates production of the hormones triiodothyronine (T3) and thyroxine (T4) in the thyroid gland.

The amount and balance of these hormones affects almost every physiological process in the body, particular your body’s metabolism (1).

Summary: TSH is a pituitary hormone that stimulates or inhibits the production of thyroid hormones from the thyroid gland.

What Makes TSH Fluctuate?

The release of TSH is first stimulated by a hormone called TRH.

Once TSH makes its way to your thyroid, levels are largely dictated by the amount of T3 and T4 in your blood.

When T3 and T4 levels are low, the body produces more TSH to stimulate the thyroid. But when T3 and T4 levels are high, the body produces less (2).

Several other factors can also influence TSH levels:

  • Inflammation of the thyroid gland
  • Genetics
  • Deficiency or excess of iodine in the diet
  • Poisonous substances and radiation exposure
  • Pregnancy
  • Certain medications- antidepressants, cholesterol lowering drugs, chemotherapy drugs, steroids
  • Thyroid cancer

Summary: Current levels of thyroid hormone in the blood significantly dictates TSH levels, although there are other factors though to influence it too.

Hypothyroidism TSH Levels

Due to the symbiotic nature TSH has with thyroid hormones, TSH levels in the blood can theoretically be a good marker of thyroid health.

This TSH levels chart presents a simplified version of what different readings can indicate.

TSH Levels T3 and T4 Levels Disease Condition
High High Tumor of pituitary gland
Low Low Secondary hypothyroidism
Low High Grave’s disease
High Low Hashimoto’s disease

Those with Graves’ disease (an overactive thyroid) have high low TSH and subsequent high thyroid hormone levels. Hashimoto’s disease (underactive thyroid) is the opposite.

Summary: Low TSH typically indicates excessive thyroid hormone levels, while high TSH indicates thyroid hormone deficiency.

Normal TSH levels

Normal TSH levelsNormal TSH levels for the average adult range from 0.4 ‑ 4.0 mIU/L (milli-international units per liter) (3).

However, many organisations agree that a reading of 2.5 or less is truly ideal, with anything 2.5 – 4.0 mIU/L considered “at risk”.

For those on thyroxine, goal TSH level is between 0.5 to 2.5 mU/L.

The reference ranges alter slightly as we grow older and if you are pregnant:

TSH levels for premature birth (28‑36 weeks)

  • 0.7‑27 mIU/L

TSH levels for children

  • Birth to 4 days: 1‑39 mIU/L
  • 2‑20 weeks: 1.7‑9.1 mIU/L
  • 21 weeks to 20 years: 0.7‑64 mIU/L

TSH levels for adults

  • 21‑54 years: 0.4‑4.2 mIU/L
  • 55‑87 years: 0.5‑8.9 mIU/L

TSH levels during pregnancy

  • First trimester: 0.3‑4.5 mIU/L
  • Second trimester: 0.3‑4.6 mIU/L
  • Third trimester: 0.8‑5.2 mIU/L

Small variations in results can occur depending on the laboratory and its methods used, as well as the time of day your blood was taken.

Summary: Normal TSH levels range from 0.4 ‑ 4.0 mIU/L for the average adult.

High TSH Levels

High TSH levelsA TSH reading above 4.0 mIU/L is considered high (elevated).

High TSH levels typically indicates an underactive thyroid gland, which produces too little thyroid hormone. This is known medically as hypothyroidism.

Common causes of hypothyroidism include an autoimmune disease (known as Hashimoto’s disease), radiation treatment, or surgical removal of the thyroid gland.

Replacing thyroid hormone and altering your diet are crucial for the safe and effective treatment of an underactive thyroid.

Summary: High TSH levels for the average adult are 4.2 mIU/L and over. This reading typically indicates an underactive thyroid.

Low TSH levels

normal TSH levelsA TSH reading below 0.4 mIU/L is considered low.

Low TSH levels typically indicates an overractive thyroid gland, which produces too much thyroid hormone. This is known medically as hyperthyroidism.

It can be caused by an autoimmune disease (known as Graves’ disease), goiter, excessive iodine in the body, or an overdose of synthetic thyroid hormone.

Initial hyperthyroidism treatment can involve anti‑thyroid medications and radioactive iodine to slow down thyroid hormone production. Most respond well to hyperthyroidism medications and are treated successfully.

Summary: Low TSH levels for the average adult are less than 0.2 mIU/L. This reading typically indicates an overractive thyroid.

The Problem With Relying on TSH

normal TSH levelsTSH is the most well-studied marker for judging thyroid health and function.

It has been the gold standard test for decades, and is considered the most sensitive and accurate indicator by most endocrinologists and other doctors.

However, more recent research indicates our systematic reliance on TSH is missing the mark. This leaves a lot of hypothyroid cases either misdiagnosed or undiagnosed.

Some clinical studies have found that both T3 and TSH levels can decline at the same time, particularly in obese individuals that lose weight (4, 5).

That means T3 levels can be low, yet TSH will remain in the normal range.

Certain medications, such as metformin, are also known to independently lower TSH levels in diabetics and PCOS patients with thyroid issues (6).

These variables are just the tip of the iceberg, but highlight why TSH is not completely reliable on its own. Considering the pituitary gland (which produces TSH) is unique in its function, it makes sense that some metabolic processes and outside stressors can influence TSH activity.

This is something to discuss with your doctor if your TSH readings are high-normal, yet you still feel seriously unwell.

Summary: Several external stressors are known to influence TSH levels, independently of thyroid hormone levels. This means TSH on it’s own is not always a reliable indicator of thyroid health.

TSH Tests at Home

It’s not uncommon for doctors to skip over TSH testing if they do not believe there is a thyroid issue.

Fortunately, there is reliable way to measure TSH yourself with a home-testing kit. It’s FDA approved to be as accurate as a blood draw test, and results are sent direct to you by email or phone call.

Have a read of the interesting reviews, as there’s the occasional comment that results are slow to get back.

Additional Tests For Thyroid Health

Given the potential inaccuracies with TSH on its own, comprehensive screening of thyroid health should ideally include these 6 tests:

  • TSH
  • Free T3
  • Free T4
  • Reverse T3
  • Thyroid Peroxidase Antibodies
  • Thyroglobulin Antibodies

Your doctor should be aware of these tests.

  12. Betty Iniguez says:

    Hi Joe! I’m 46 years old and was recently diagnosed with hypothyroidism in June of this year. My most recent labs from 8/24, were all within the “normal range” but I know they are not where they should be:
    TSH-Icma 0.93
    T-3, Serum 77
    Free T-3 2.3
    Free T4 1.2
    Thyroglobulin Antibody <1.0
    Thyroid Peroxidase (Tpo) Ab 6
    Following my most-recent lab results, I was switched from Synthroid (50 mcg)/Liothyronine (5mcg 2 x's daily) to Nature-throid 48.75 mcg which I started two weeks ago. My biggest concern is my body won't respond to diet, even after I cut out everything processed, sugar, starch, dairy, liquor.
    I'm taking an adrenals saliva test tomorrow and just requested a hormone panel, and a review of my Glucose, Serum which has dropped to 92 but was in the pre-diabetic range when I started the thyroid meds (99). My fatigue is improving but I'm too tired to workout. I've always been in good shape and had a good metabolism so all of this is very frustrating and depressing. Is there anything in particular I should be tested for? My dr did mention I'm not premenopausal.

  17. Hi just diagnosed with hashimoto s and don’t want to start taking hormone until ive exhausted diet changes. I’ve been told you can put into remission with a type of paleo diet . I’m away for 6 weeks and will do this when I get back from India . Have you heard this is possible or taking hormone while putting in remission is way to go

  33. Judy Olson says:

    I am curious as to why the TSH range, for adults, changes so dramatically after age 55.

    I am 57 years old with a TSH of 3.8, which sounds like I should be right on target, but it seems like the normal range is huge. I have several symptoms, like dry skin and hair, muscle weakness, tingling sensations in my legs and feet, joint and muscle pain and I haven’t slept well, in years.

    I’m concerned that the range may not be telling the whole story. Since there is no personal baseline TSH number, how do I know that my test results are truly normal. Maybe my true normal is .8.

  34. Hi

  42. Ramjee sah says:

    My wife is 25 yrs& 43 kg.Free T4- 0.18ng/dl &TSH- >500.0 IU/ml results by Diagno Labs Pvt. Ltd. India reported on 07/01/2017.Now, Taken one tab. Thyronorm 75 mg daily morning before meal from 1 month but not any sign/symptoms is lose or like no any advantages. I am unable to think, how to do this condition. I deeply hope you given to me any Idia or Advice…plz.

  43. I’m a 2x cancer survivor – 53 yrs young – have had radiation treatments at my chest and chemotherapy. at 34 I went into menopause and have had hypothyroidism since – always weighed about 100lbs Wish I still did) – eat very good – been a gym rat my whole life – my issues –

    I seem to have become allergic to every thyroid medication given to me – I got off Synthroid because the side effects on me were horrible, same with the generic stuff – my body cannot tolerate foreign chemicals, pharmaceuticals. I pleaded with my Dr to put me on Armour which he did – what a new life I had – hadn’t felt so good in over 10 years – then one day I woke up having difficulty breathing – thought I had pneummonia – was actually my body rejecting the Armour with an allergic reaction – my throat was closing up – so Dr. knocked down my dosage and I monitored what I took – back this past June I was extremely stressed at a horrible job and it all happened again – so Dr switched me to Naturethyroid – another natural medicine – after about 2 months I started having the same problems but what happened to my stomach was crazy – bloating so that I looked like I was 9 months pregnant but it was what my stomach looked like – huge!! on someone 5′ tall I looked like the python that swallowed a goat. So I stopped taking it immediately and started the Armour – now again same problem with the Armour – difficulty breathing, heart racing – eyes twitching, exhausted, serious rashes especially in my armpits, out of sorts.

    Going to see my Dr this week but honestly get the feeling he doesn’t really care about how I feel, if I am supposed to be on medicine for the rest of my life for this disease then what the heck am I supposed to take if I’m allergic to everything?

    Any suggestions from anyone who has gone through this even slightly I would appreciate it – not really sure how much more of this I can deal with, seems like a lifetime and I just want to feel good

  44. Hai i am female age 22year

  48. Joe – can I check with you source of your normal TSH ranges. I thought your TSH range for children seems high, considering ranges followed by most labs and those discussed in research papers available on ncbi website. Is it possible for you to confirm – this is quite important for us… Thanks for your great article… Best…

    The doctor hasn’t called me yet with my results, I have online access to my results as soon as they process and am very curious to what it could be or what to do, but in the meantime and wondering if there are any foods I could eliminate BUT. I have lost 40 lbs (I wasn’t obese). I had 5 major surgeries on top of the cancer in 6 months which left me sedentary on top of 18 meds. My diet has been oats, sprite added in steak for protein, I can’t eat ground been (first surgery was gallbladder that’s how they found the cancer). I don’t eat breads, nor milk or any dairy products 6 strawberries for breakfast daily, a chicken breast grilled, no starches like rice.

  108. Nina Oreilly says:

    Hey ! I’m definitely not asking for anything that would be against my doctor, I’m just really really in a spot that sucks. My doctor is very very very …. slow …
    I’ve been literally like feeling like I’m dying, no energy, weak, and to put it short, every single symptom of thyroid problem. And this has been absolutely devastating and I’m in bed 24/7
    I finally got my results and I’m just asking you to please help me figure out if these are abnormal results and if so, how far off. ? Not asking for a diagnosis, just wondering how far off the numbers are, because it’s very very frustrating trying to take in all the information online and apply it to my results as they seem to be measured differently 🙁
    TSH 14.8
    Free t3- 13
    Free t4- 5.0

    Also, I’ve had this problem with the constant lack of energy for as long as I can remember. I can remember being 7 and my brother having to literally drag me out of bed for school. lol.
    And in high school I couldn’t understand how everyone always had so much more energy than me…
    Is it at all possible that I’ve had a problem with thyroid my whole life ,?
    I’m 29 and I’ve been tiny my whole life. I have a bit more meat as I’ve had a baby 3 years ago, but I’m still small ! If that helps !

    Sorry for the story. It took sooo much to finally come and ask, I tried to figure it out myself because I hate bothering people.
    Thank you in advance.

    Hi Joe,
    I am 53 year old female. Had my thyroid removed 18 months ago due to pre cancerous nodules and was diagnosed with hypothyroidism. I am currently taking 137 mg of levothyroxin. 12 months ago I had my tonsils out and at this time was told I have low blood pressure. My concerns are I have put on 40 pounds since the surgeries and am having trouble getting it off. I am tired all the time, dry skin and can’t seem to get back into exercising. I was average active before. Two doctors have told me to go a carb free diet
    Had my blood work done everything stayed about the same except for my TSH(high sensitivity) on 5/1/2017 it was 1.77 and on 10/19/17 it was 3.6 mIU/L
    First of all what does the tsh monitor and what does it mean. Secondly any suggestions with the weight loss would be appreciated.
    Thank you in advance

    T3 total 0.85
    T4 total 3.49
    TSH 55.
    which type of tyroid is this
    And what is diet
    And what to do in it

  145. Hi my name is Epheson Im 19 years old my T3 is 0.96
    T4 6.45 and TSH 0.53.I know its between the reference but I read and also once a dermatologist told me it will have a great effect on my skin specially on my skin and through years it really did affected my hair. My hair has been like 80 year old woman and i think its related with the surgical removed gall bladder.

  146. Hi sir my tsh level is 12.7 i m 22 yrs old my doctor prescribed me thyroxin sodium 100mg when will my tsh level gets to normal

  147. Thanks for the article, Joe!
    It is so much more clear to me now.
    I was diagnosed with hypothyroid about 3 years ago when I was 28 and recently decided to get off T4 and you know it worked (so far)! I increased my activity (workouts with a trainer and cardio days at a gym), added some supplements and excluded gluten and dairy from my diet (thanks to my trainer, who is also recommended calories intake, proportions and all the supplements). It has been about 2 months I am not taking T4 any more and blood work came out normal! So it is possible to not take T4 and have your thyroid back to normal life. Thanks for the article again, it helped me to realize that I am not the only one suffered from hypothyroid and helped to figure out on how to read my blood work!

      Hi Megan, since I do not know your personal medical history, I cannot say what it might be. You should go back to your doctor and discuss other avenues you could explore. Good luck.

  149. Amanda Rhodes says:

    I’ve been diagnosed with type 1 diabetes and Hashimoto’s Thyroiditis for over 30 years. My last numbers from back in early October was a TSH of 0.29 and my Free T4 was 1.4, I was upped from 300MCG to 350MCG of Levothyroxine about a month before the last test because my numbers were so bad (I don’t have the numbers from the test before). I still have the puffy eyes, can’t remember things can’t concentrate well, still can’t lose the weight that I gained when my levels went haywire and always feel exhausted. Can you tell me if I should already be feeling better and seeing a differnce and is there anything that you can suggest to help decrease the symptoms? Thanks a bunch.
