The distinctive range of mention for TSH levels is anywhere between 0.45 and 4.5 milliunits per liter ( mU/L ). A recent learn suggests that the normal roll should be more comparable 0.45 to 4.12 mU/L. thyrotropin can vary wildly based on your age, sex, and stage of biography. For case, a 29-year-old woman may have normal TSH around 4.2 mU/L, while an 88-year-old man may reach 8.9 mU/L at their upper limits. And stress, your diet, medications, and having your period can all make TSH fluctuate. thyrotropin levels change inversely with how much thyroid hormone is in your body. Think of your pituitary gland as a thyroid thermometer :
- Abnormally high TSH levels usually mean that your thyroid is underperforming. Your pituitary gland reacts to a lack of thyroid hormones by producing extra TSH to make up the difference. This is called hypothyroidism.
- Low TSH levels usually mean that you’re producing too much thyroid hormone. Your pituitary gland responds accordingly by decreasing TSH production to get thyroid function under control. This is called hyperthyroidism.
Let ’ s memorize more about the range of TSH levels for different groups of people and what to do if your level is besides eminent or excessively gloomy. here are the calculate normal, humble, and high ranges of TSH levels for adults, based on a 2013 study :
|18–30 years||0.5–4.1 mU/L||< 0.5 mU/L||> 4.1 mU/L|
|31–50 years||0.5–4.1 mU/L||< 0.5 mU/L||> 4.1 mU/L|
|51–70 years||0.5–4.5 mU/L||< 0.5 mU/L||> 4.5 mU/L|
|71–90 years||0.4–5.2 mU/L||< 0.4 mU/L||> 5.2 mU/L|
TSH levels in men
Both high and low TSH can affect birthrate. serviceman with hypo- or hyperthyroidism both had fewer normally shaped sperm. And men are more susceptible than women to complications like irregular development of the genitals if they have high TSH. Taking thyroid hormone successor therapy may be necessary for men to balance TSH.
TSH levels in children
thyrotropin levels in children can vary based on their age :
|0–4 days||1.6–24.3 mU/L||< 1 mU/L||> 30 mU/L|
|2–20 weeks||0.58–5.57 mU/L||< 0.5 mU/L||> 6.0 mU/L|
|20 weeks – 18 years||0.55–5.31 mU/L||< 0.5 mU/L||> 6.0 mU/L|
A 2008 report that close measured TSH levels in kids from parturition to arsenic old as 18 years found wildly unlike TSH levels throughout their lives.
And though TSH tends to be high for the first base month after they ’ ra born, a child ’ mho TSH levels will gradually decrease as they get closer to adulthood before rising again as they age .
TSH levels during pregnancy
The chart below shows you how to know when your thyrotropin levels are normal, depleted, and gamey when you ’ re pregnant, specifically between the ages of 18 and 45 :
|Stage of pregnancy||Normal||Low||High|
|First trimester||0.6–3.4 mU/L||< 0.6 mU/L||> 3.4 mU/L|
|Second trimester||0.37–3.6 mU/L||< 0.3 mU/L||> 3.6 mU/L|
|Third trimester||0.38–4.0 mU/L||< 0.3 mU/L||> 4.0 mU/L|
It ’ randomness authoritative to monitor TSH levels during pregnancy. high TSH levels and hypothyroidism can particularly affect chances of a spontaneous abortion. As a result, a small percentage of fraught women may receive levothyroxine ( Synthroid ), methimazole ( Tapazole ), or propylthiouracil ( PTU ) to help control TSH and thyroid hormone levels, particularly if they have hypo- or hyperthyroidism. If you ’ re fraught and already taking this medicine for abnormal thyroid hormone levels, your doctor may recommend increasing your dose by about 30 to 50 percentage. successful treatment of high TSH and hypothyroidism during pregnancy can lower your chances of having a spontaneous abortion. Control of TSH levels can besides help prevent other pregnancy complications, such as :
- giving birth prematurely
- having a baby with a low weight at birth

Your doctor may recommend one or more of the adopt treatments for abnormal levels of thyrotropin :
Hypothyroidism (high TSH)
- daily medications, such as levothyroxine
- natural thyroxine hormone extracts and supplements
- consuming less of substances that affect levothyroxine absorption, such as fiber, soy, iron, or calcium
Hyperthyroidism (low TSH)
- oral radioactive iodine to shrink your thyroid gland
- methimazole or propylthiouracil to keep your thyroid from making too much thyroid hormone
- removal of your thyroid gland if regular treatments don’t work or may be threatening to your health, such as during pregnancy
abnormal TSH can indicate that your thyroid gland international relations and security network ’ triiodothyronine functioning by rights. This can lead to long-run complications if you have an fundamental discipline that leads to hypo- or hyperthyroidism.
