TSH and So-Called “Normal” TSH Levels: A Non-Sciency Guide

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 levels should be and how it relates to hypothyroidism.

Note that each section in this article has a ‘summary’ box (like this one) to save time. Below this box is a contents menu to help you navigate directly to a particular section.

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 the thyroid stimulating hormone 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 your levels, although there are other factors that influence it too.

Hypothyroidism: What is TSH Level?

Due to the symbiotic nature they have 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 LevelsT3 and T4 LevelsDisease Condition
HighHighTumor of pituitary gland
LowLowSecondary hypothyroidism
LowHighGrave’s disease
HighLowHashimoto’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 levelsWhat should your TSH level be?

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

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

For those on thyroxine, the ideal TSH normal range is between 0.5 to 2.5 mU/L.

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

TSH Normal Range By Age:

For premature birth (28‑36 weeks)

  • 0.7‑27 mIU/L

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

For adults

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

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 levels range from 0.4 ‑ 4.0 mIU/L for the average adult.

High TSH Levels

A level reading above 4.0 mIU/L is considered high (elevated).

What is the reason for high TSH levels?

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

High TSH levels

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 levels

A reading below 0.4 mIU/L is considered low.

What does it mean when your TSH is low?

Low 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 Solely Relying on TSH Tests

normal TSH levels

TSH 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 it 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 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.

TSH test

Fortunately, there is reliable way to measure thyroid stimulating hormones 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.

  6. Hello, I just got my test results back and my TSH result came back as 0.005 telling me it was below low normal. I’m 36 years old and not sure if this should be a concern for me. My Doctor ordered a thyroid scan. Should I be concerned at the result that came back? My Doctor did not explain much, though she did state I have hyperthyroidism. Don’t know what to think about this. Thank you!

  7. I am 53 years old.i am on tyronorm for the last 10 years.presently i am on 75 mcg tyronorm.my tsh level presently is 0.044. What would be the right amount of tyronorm mcg for me?

  8. 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.

  9. I am female, 64 years old. My TSH is .083 uTU/ml. My appointment with my doctor is still on oct. 5. What should i do?

  10. I had my thyroid removed many years ago and recently a Dr. said my TSH level was too high. It was .003. can you tell me what a normal range is?

    • A normal TSH level ages 21 through 54 years is 0.4- 4.2
      Normal TSH levels for ages 55 to 87 years are 0.5 – 8.9

  11. Hi Joe, very interesting reading however I had my thyroid removed over 10 years ago due to Graves Disease and have been taking levothroxine since then, however, when I changed area and doctor, even though I have regular blood tests and have been back to see the endocrinologist, they tell me my levels are fine, although I feel very sleepy and have put on two stone in weight, which I am struggling to lose. any ideas to help?

  12. 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

  13. My TSH result is 0.022 , so thyroid is under active ? , just started levothryroxine 137 dose , what to expect ? Thanks

  21. Hi I’m darrah my TSH level is 0 .124 uiU what should I do to increase it.i am taking Carbimazole as prescribed by my dr

  22. 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.

I deeply hope you given to me any Idia or Advice…plz.

  29. 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

  32. 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…

  59. 48 YOF Papillary thyroid cancer diagnosis sep 2016, full thyroidectomy oct 2016, radiation feb 2017. Lev was 125 to start, then increased to 137, Nov Tsh .579 T4 1.29 Dec Tsh .586 T4.96 in Feb Tsh .467 T4 1.23 upon a review. March Tsh was .804 T4 1.13 June 2017 Tsh was .005 T4 1.79. Did another review 6 weeks later (recently) after lowering Lev to 112 Tsh is still .005 and T4 is 1.54.
    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.

  60. 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 🙁
    Okay,
    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.

      I cannot give medical advice online. I would recommend speaking to your doctor/GP about this issue. Good luck.

  63. Age 35
    I got a few test’s done but don’t understand them, can you please help me?

    1) TSH with Reflex to FT4 IF IND
    TSH
    Value 1.220

    2) TSH with Reflex to FT4 IF IND
    TSH High Sensitivity
    Value 1.940

    3)TSH with Reflex to FT4 IF IND
    TSH High Sensitivity
    Value 0.870

    And my health summery says abnormal thyroid stimulating hormone and that now I have high cholesterol.

    I asked my doctor about it and he just put me on cholesterol medicine. My anxiety has gotten really bad lately, out of no where along with many other symptoms listed in the hypothyroid category. Back in 2002 I had high sensitivity asking with low iron while pregnant with my first born.

    Is this normal? What should I do if it’s something that I should be considered about?

    Thank You for Your Time

  75. 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

  76. Hi

    Awaiting for your reply….
    Thank You

    • Hi Nisha, your father should discuss this with a doctor as I cannot give medical advice online. Thanks.

  77. 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.

  78. Hi Shahidah, please go back to your doctor and ask. I cannot give personalised medical advice online. Thanks!

  79. 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 Toma, glad you’ve been having good outcomes through your diet and exercise. Good luck and keep up the good work! 🙂

  80. Just got my results of my thyroid screening from an urgent care. It’s 1.56. I’m really upset because I thought I really did have a over active thyroid.. I am loosing so much weight! Any suggestions? Is it possible they missed something?

    • 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.

  81. 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.

  82. Hi, I’ve struggled for a decade trying to get my thyroid levels in range. Latest labs show:

    VIT D 73.1
    TSH 0.342
    T4. 8.6
    T3 uptake 26
    Free T index 2.2
    T3. 113

    Recently began Low dose naltrexone, on week 8 of titration.

    I am still tired all the time with minimal energy.

    Suggestions? Thoughts?

    Thank you in advance!

  83. Hi, i am 19 years old girl my thyroid profie is :

    TSH= 0.03 ulU/ ml

  84. Hi. What are your thoughts on an at home thyroid test that uses a blood prick sample? I was looking at one from Health Test Express that screens for Free T3, Free T4, TSH, and TPO. Looks like they also provide a doctor consult to help understand the results or refer to specialists. Here’s the link if you can provide your feedback: https://www.healthtestexpress.com/thyroid-test-panel/

  85. Hi Joe,

    • Hi Seema, please contact your doctor for advice. I cannot supply medical advice over the internet. Thanks 🙂

  86. I am a 21 year old male. I am really skinny and not gaining weight by any means. I checked my thyroid it was -.83 ml. Am i not gaining weight because of this high rate of thyroid hormone.

  87. I am a 45 year old female. I resented had bloodwork done and my tsh level was 20.66. The dr started me out on 50 mg of levothyroxine.

    Is there anything I should be aware of with a level that high?

    • Hi Teresa, no just take the levothyroxine and it will reduce your levels back to a normal range.

  88. Hi,
    Iam 26 yrs old Female with 5 week Pregnant and my thyroid levels are
    T3 is 145 ng/ml
    T4 is 10.47 ug/dl
    TSH is 5.97 ulU/mL

    and my doc suggested that my TSH is high and i should be on THYROXINE medication.
    .. Here my question is, My TSH is already high and why my doc suggested to take Thyroxine Tablets?
    Will Thyroxine reduce the TSH.
    Please advise me.

  89. Hi. I’ve had radioactive iodine ablation therapy. My last test results were TSH 5.44 with T3 3.1 and T4 19. I am having hypothyroid symptoms again. My doctor said all is well and to repeat blood work in 3 months. Should I be getting a 2nd opinion?

  90. Serum TSH level 2.7 miu/L [0.35 – 4.94]

    These are the results I have gotten today… I’m on thyroxine and can see my levels are normal but how can I tell if my t3 etc has been checked?

  91. I went to my doctor and shared my symptoms and he suggested it might be my thyroid. I got my blood drawn and it was 5.7 and he told us he wanted to take it again. The second time it was 4.7 so he decided the thyroid wasnt the issue. I think the thyroid still might be the issue. What do you think and what should I do next?

  92. Hi, I’m 63 and feel somewhat fit , during xmas season I gain a little and in the summer back to slimm 5″8 tall, 140 weight, just received a reading of 8.5 whatever it means , doctor said it’s to high and wants to put me on meds for thyroid and high cholesterol if 190 .

  97. Hi am 26, my tsh range is 7.45 two years back. After I taking tablet of 25 mg, before six month am having tsh range of 3.85. Still am continuing 25 mg tablet. But my peroids are irregular. I don’t know whether my hormone imbalance is normal or not. Can I plan for a baby.

    • Go see your doctor, endocrinologist preferred. Pregnancy requires higher levels of thyroid hormone, esp in the first trimester for optimal neural development of the baby and to prevent miscarraige. TSH should ideally be less than 2. Usually a higher dose is given. Also, for max absorption of levothyroxine, make sure you are taking it by itself 30 mins before any food or ingesting anything else. Taking it any other way will lead to poor absorption and higher TSH.

  98. Hi There,
    Soon to be a 57yr old woman here!!!!! Had blood work and my T3 came back as 90!!!!!!! My doctor now wants more bloodwork for TSH to rule out an under active thryoid!!!! Shouldn’t that have been part of my normal bloodwork??????
    (((((((By the way I am moody, itchy cranky, tired, constipated, forgetful, cold and sombody shrunk allllllllllll my clothes since before the holidays!!!!!!!!!! I suspect this is how the Queen of England feels…………because she
    Never Smiles ))))))) AT least I still have my sense of humor ?

  99. I hat the back of my head severely in 2007 and within 3 weeks i gained 4 lbs. ..no energy ..sleep 9 hrs.nite …loss of concentration …./ by the end of 4 months i had gained 35 lbs …eating less and symptions increased dramatically ….one doctor felt my pituitary gland was inactive due to the concussion …/ my last blood test results show TSH at 0.031 / T4 FREE is 1.10 / T3 ICMA is 5.4 …../ i am a 71 woman and now im sleeping 10 to 11 hours a nite ….no energy ….no train of thought …thin hair ….dry skin …lsplitting nails ….my weight is 162 lbs. and try to walk but have to nap when i get home ….i used to be hyper all my life and never got sick until i hit my head …i am taking Armour Thyroid 90mg.daily but my doctor wants it reduced …should i

    • I’m not a Dr. But I had similar normal blood work and I just felt awful. My Dr. Sent me to have an ultrasound on my thyroid and I had a huge mass. I ended up having it removed. I am now on thyroid meds. And we are still trying to figure out dosage a year later but I feel much better. I like to rely on how I feel now. You hear of so many cases in several different medical areas were people just knew something was wrong. Even when the test showed there wasn’t. I believe you know your body make them run all the test until you figure out what is wrong. Good luck and I hope you feel better.

    • High , I had my skull spilt open at the back too. I also feel the same as you and I was super active until my accident. I gained a lot of weight and really didn’t eat a lot. I feel my pituitary gland as been compromised in some way.

  100. I also had elevated vit.B6 at 63.9 / carbon dioxide at 29 / glucose at 101 / elevated cholesterol levels and high Hct of 48.0 ……i walk 1.5 miles once a week as no more energy and want to exercise more but no energy …..i am 15 lbs over weight and eat healthy but to no avail

  101. yomi, it is more likely that you were diagnosed with hypothyroidism in the first place…otherwise you would not have been prescribed the thyroxin. when you quit taking the medication, you became hypothyroid again.

  102. Is 3.55 of THS reading normal? I have Graves and hashimotos and been on Methimazole since first diagnosed, I’m taking 2.5 only on Monday, Wednesday, Friday once a day. Thanks for any information.

  103. My husband just turned 88. He had his thyroid blown away through radiation at least 25 years ago and has been able to control the TSH level with medication for the most part with various changes for all of these years. He recently has had a variety of readings: 1.3 (4/2016), .07 (10/17) and now .09 (2/2018). His doctor has changed his Levothyroxin from 175 mcg, 200 mcg to now 2-125 mcg per day. He has never had that high of a dose before…should I be concerned? Perhaps it is time to see someone other than his PC for this?

  104. I was diagnosed with hypothyroidism over 20 years ago. I had been taking 75 mcg levothyroxin for several years, with TSH levels ranging from1.8 – 2.8. After having routine blood work last week, the TSH level was 48.6, had gained five pounds in one week and feel extremely weak. My doctor increased the levothyroxin to 100 mcg. What are some causes of such an increase in TSH?

    • I am 77 I have been dealing with hyperthyroidism for 25 years I am hungry all the time it affects my sleep terrible I am completely exhausted I ask my doctor to give me an ultrasound something is very wrong I am just unable to do anything I don’t know if my TSH if that is too high nobody tells me anything could someone please help me and give me some answers I would like to know what I should eat so I won’t be so hungry all the time thank you

    • You have to take levothyroxine on its own and about 30 mins before any food or ingesting anything else, or else it will not absorb properly in your gut and consequently lead to elevated TSH levels.

  105. Just had a test and said (value) 16.88 reference range 0.4 .. is it saying I’m above the reference range ? That’s kinda high

    • Hi there normal range is 0.4-4.5. Based on that your 4.92 means your score is high which means your thyroid is under producing

  106. My tsh level is 1.78. T4 level es 1.02 ng/dl. Now I am suffering from low back pain & muscle pain. Is this thyroid level is sufficient?

  107. my T3 level is 92.93, T4 level is 7.75 and TSH level is 1.212 . is this normal or have thyroid problem? even i test with the glass of water as well
