What are different types of thyroid levels?
Know the contribution of thyroid levels to make your body work, as it plays an important role to keep us going and in a good state of mind and health.
Human beings are considered as the best creation of God, as god engineered human beings to atmost of his perfection.
And there is a reason behind it, as there are many complex systems running in our body which are working day and night just to keep us alive and kicking.
Some of the systems are with duct or pathways and there is one which is ductless as well means there won’t be any passage or pathways by which the fluids and other nutrients will pass (guess humans got the concept of Wi-Fi from this only).
The only ductless system of our body is known as the endocrine system as the main work of this system is to secrete hormones throughout the body.
The system has many glands like pituitary gland, parathyroid gland, pancreas, gonads, pineal gland etc. And one of the most important glands of this system is thyroid gland.
Thyroid is the gland situated in the front part of the neck just below Adam’s apple, the main function of the thyroid gland is to secrete the thyroid hormones and to maintain the thyroid levels of the body.
The thyroid is a butterfly-shaped gland and it releases hormones that control the metabolism of the body, thyroid has two side usually called lobes that lie on the each of the either sides of the windpipe.
The work of thyroid gland is to produce, store and release the hormones into the bloodstream of the body so that it can reach to the required cells and more importantly to maintain thyroid levels.
The thyroid gland uses the food we eat and take the help of iodine to produce two main hormones that constitute the thyroid levels in our body which are:
- Triiodothyronine (T3)
What are the use and need of thyroid gland?
The main function of T3 and T4 travel in your bloodstream so that it can reach to almost every cell in the body, it is also responsible for the speed which is required for the metabolism work and T3 and T4 constitutes thyroid levels.
What are thyroid levels?
Thyroid levels are the level of the hormones in the bloodstream and the body which are responsible for the many of the other activities of the body like breathing, heart rate, body weight, muscle strength, body temperature, muscle strength, central and peripheral nervous systems, menstrual cycles and much more.
So, for that, the body has to regularly maintain the optimum thyroid levels in the body, and in many of the cases the level may go up and down and there are consequences for that as well which the person has to suffer.
Thyroid levels chart
It’s very common to us to sometimes feel tired or maybe sometimes depressed, maybe at that time, you can check your thyroid levels in the body.
There are conditions when the thyroid gland does not release the required sufficient hormones, and that particular condition of the imbalance is described as hypothyroidism.
And the condition when the production of the thyroid hormones and the thyroid levels are noticed to be excessive then it is required is known as hyperthyroidism.
|T3(Serum triiodothyronine)||80-220||T3<80 indicates hypothyroidism|
|T4(Serum thyroxin)||4.5 to 12.5||T4<4.5 with elevated TSH indicates under-active thyroid.
T4<4.5 with low TSH suggests a pituitary problem.
|TSH||0.3 to 3.0 (as of 2003, revised by the American Association of clinical endocrinologists) but many labs or doctors follow the old number 0.4 to 6||TSH <0.3 indicates hyperthyroidism and TSH>3.0 indicate hypothyroidism.|
With the total T4 level, the levels of ‘Free T4’ are also measured 0.7 to 2.0 is considered to be normal range for “Free T4”, and in the same way the “Free T3”, and this levels are also measured and 2.3 to 4.2 is the normal range of “Free T3”.
Normal thyroid levels
The normal range of TSH level is around 0.4 to 4.0 milli-international units per liter, and the normal range of the thyroid levels is 0.5 to 3.0 milli-international units per liter.
In the cases when the normal range of thyroid levels exceeds its value and in that case it is indicated that the thyroid is overactive. And in this kind of cases, the pituitary gland releases more TSH to stimulate it, as at that time the condition comes under hyperthyroidism.
And on the contrary, when the thyroid levels don’t exceed the normal value of the thyroid hormones then it indicates as a underactive phenomenon, it is just opposite of hyperthyroidism.
As here the glands are underactive so with results it can’t produce the required amount of hormones for the bloodstream and the body as well.
Thyroid levels low
This is also known as the Hypothyroidism, as these glands cannot produce enough hormones that are being required in the body, so they are being termed as underactive hormones.
There are certain factors which lead to Hypothyroidism or low thyroid levels in our body and Hashimoto’s disease is one of the prominent cause of it.
Hashimoto’s disease has caused an enormous amount of chaos among the people as according to the census 4.6 percent of the population above the age of 12 years and above are affected by this disease in the United States of America.
The common symptoms of Hypothyroidism are as follows:
- Dark skin
- Sensitivity to cold
- Psychological changes
- Memory problems
- Regular constipation
Diagnosis and treatment of Hypothyroidism or low thyroid levels
The best way to diagnosis Hypothyroidism is by having a blood test, as by this we can measure the TSH and thyroid levels in the bloodstream.
As a high level of TSH level along with the low thyroxin in blood will signify that the thyroid levels of the body is underactive, and for that purpose the master gland of the body( pituitary gland) has to release more TSH to try to stimulate and trigger the thyroid gland to make the more amount of hormones .
The main the only treatment for Hypothyroidism is to take the thyroid hormone pills. And you need to take care of the right amount of the dosage until the thyroid levels are back to normal, otherwise, it may react in a different way.And too much of the dosage can lead you to the symptoms of hyperthyroidism as well.
Commonly known as the chronic lymphocytic thyroiditis, one of the most vicious diseases as it has affected around 14 million Americans.
In this disease, there is “age no bar” factor as it can affect any of the people of their respective age group, but women’s lying in the middle age category are the common victims of this disease.
Studies have found that when the immune system of the body mistakenly takes an offensive mode against the thyroid glands then it slowly destroys them and also to the ability to produce hormones and also depletes the thyroid levels.
In many of the case, it has been found that there are no obvious symptoms seen for years when the disease is mild, and the interesting thing about these diseases is that the symptoms are not always specific as it can mimic the symptoms of the other conditions.
But still some of the common symptoms are as follows:
- Mild weight gain
- Dry skin
- Thinning hair
- Pale and puffy face
- Goiter (enlarged thyroid)
The children can get different types of hypothyroidism which are as follows:
- Congenital hypothyroidism occurs if the thyroid glands are not fully developed during the time of birth, as out of every 2500 to 3000 babies born one is affected by this disease in the United States of America.
- Latrogenic hypothyroidism develops when the thyroid gland in the child get destroyed by some of the reason or removed by some or other reason like surgery or accident.
- Autoimmune hypothyroidism is basically caused by the autoimmune disease, and in this, the immune system attacks the thyroid glands and depletes the thyroid levels in the body, it affects more in the teenage days, and it is most common in girls than boys.
High thyroid levels
Also known as the Hyperthyroidism or high thyroid levels, as these glands produce more than the required amount of the hormones, so they are also termed as the Hyperactive glands.
And the excess of the hormone in the bloodstream results in the speeding up of the metabolism process at very higher scale.
The some of the common symptoms of Hyperthyroidism are a rapid increase in the appetite, having lots of anxiety, having difficulty in sleeping and much more in the list.
The main cause of Hyperthyroidism is because of the Grave’s disease, it comes in the category of autoimmune disease which is not at all preventable.
And as mentioned above in many of the cases the high dosage if the medicines can lead you to the Hyperthyroidism, so we need to be always careful about the dosage and all of the Hypothyroidism.
As already mentioned above, this disease is not preventable but with our efforts, we can minimise the complications by getting treated at the right and earliest possible time.
One of the most common forms of Hyperthyroidism as it engulfs 1 in every 200 persons in the United States of America.
Grave’s disease is also one of the kinds of autoimmune disease and occurs when the body’s immune system attacks the thyroid glands, which results in the overproduction of the thyroid hormones and a hike in the thyroid levels of the body and regulates the metabolism.
The most common age prone to this disease is 20 years to 30 years, it is a unisex disease as it can occur to both men and women at any age.
When there is an excess of the thyroid hormone present in the bloodstream, then there are certain changes which the body receives which are as follows :
- Hand tremors
- Increased heartbeats
- Altered menstrual cycle
- Irregular heartbeats
- Difficulty in sleeping
- Vision problems
Diagnosis and treatment of Grave’s disease
A physical exam of the body is required and it can diagnose the enlarged thyroid, some of the symptoms are also seen during this physical exam like the bulging of eyes, the rapid increase in the heart and pulse rate are seen.
A blood test is advised to check the amount thyroid levels like T4 level and levels of TSH, till today’s date there is no treatment available for the Grave’s disease and which can stop the overproduction of the hormones.
But the symptoms of the Grave’ disease can be controlled by some of the following ways which are as follows:
- By giving the radioactive iodine so that it can plunder all or maybe some part of your thyroid.
- Sweating, anxiety and rapid and irregular heart rate can be controlled by beta-blockers.
- Surgeries can be performed to remove the thyroid gland.
Thyroid stimulating hormone level
It is thyroid-stimulating hormone(TSH), when there is the release of thyrotropin by hypothalamus then TSH is being produced.
TSH helps in making the thyroid gland to make the following hormones :
The work of these two hormones is to help in controlling the metabolism rate of the body, they are also important in maintaining the normal growth of the brain in the first 3 years of childhood.
If any of the children don’t produce T3 and T4 in their body then they may suffer many of the severe circumstances and mentally retarded is one of them.
Whereas the grownup child needs thyroid hormones for maintaining normal thyroid levels and also the proper and normal growth of the body.
Tests that are being done for TSH
- Basically to find out whether the glands are working properly or not, as because an underactive thyroid gland can cause symptoms like weight gain, feeling of being cold and irregular menstrual periods.
Whereas any overactive thyroid can cause some adverse effects like weight loss, rapid heart rate, nervousness and much more.
- To find the main cause of the hypothyroidism.
- To keep an eye and also to track down the treatment with thyroid replacement medicines for people who are suffering from hypothyroidism.
Optimal thyroid levels during pregnancy
Believe it or not, the thyroid gland plays a pivotal role in the development of the baby from the early pregnancy days, as it regulates the flow of T3 and T4 which plays the main role in the development of the baby’s brain and nervous system.
During the first trimester days, the thyroid gland of the mother enlarges a bit than normal as because the growing fetus totally depends on the mother’s supply of thyroid hormone.
And in order to meet that need the mother’s thyroid production typically goes high which results in the high thyroid levels and enlargement of the thyroid gland just to meet the need of baby and also of the mother.
This phenomenon goes unnoticed as it doesn’t complicate the pregnancy in any of the ways, but in some of the cases it goes noticeable and in that case, the mother is said to be having hypothyroidism.
The master gland or the pituitary gland is responsible for the production of T3 and T4, and as the normal thyroid levels and function is different than the normal days, the value of TSH also changes as the mother progress from the first trimester to third.
The normal TSH value lies between 0.2 to 4.0 mIU/L. And if in any of the cases the value drops from the this given range, then that stage is considered to be hypothyroid state and proper medicines are given to keep it up and normal.
Monitoring TSH during pregnancy
According to the American Thyroid Association(ATA) the following ranges are being used and seen:
- First trimester: 0.1-2.5mIU/L
- Second trimester:0.2-3.0mIU/L
- Third trimester:0.3-3.0mIU/L
It is advised that you should get regularly monitored throughout the pregnancy period.
Causes of increased thyroid levels
As we have already discussed above the increase in the thyroid levels is known as Hyperthyroidism,
As this is the condition in which the thyroid gland over produces hormones and known to be overactive, and there are many reasons that can cause hyperthyroidism or high thyroid levels which are as follows:
The one of the main reason of Hyperthyroidism is Grave’s disease as it causes the antibodies to stimulate the thyroid to produce more amount of hormones.
Some of the other reasons and causes of hyperthyroidism are as follows:
- Excess of iodine in the body
- Tumors of gonads
- Inflammation of the thyroid gland
- Benign tumors of the thyroid or pituitary gland.
- A Huge amount of consumption of tetraiodothyronine in the diet.
Above mentioned are the some of the main causes of increased thyroid levels.
Testing thyroid levels with thyroid blood test
One of the most common blood tests for testing thyroid levels is the T4 test and TSH test, and the other name of the T4 test is thyroxine test.
Now some of the common blood tests for thyroid levels are as follows:
- TSH tests
The one of the best way to check the thyroid levels is to check the TSH level in the bloodstream, the low level of TSH in the bloodstream indicates that there is excessive production of hormones whereas the high level of TSH in the blood shows that there is the lower production of hormones.
- T4 tests
Commonly known as the thyroxin test is basically done to know the over or underproduction of hormones is because of the imbalance in the master gland or the pituitary gland.
- T3 tests
T3 tests are being done just to check the seriousness of the hyperthyroidism or high thyroid levels, this is one of the most important tests to determining the hormone configuration via thyroid gland.
It is also considered to be important in the case of hypothyroid tolerant as it is the last test to end up emphatically.
The values of thyroid function test
|TSH||0.4 to 4.0mU/I(milliunits per litre)|
|T4||9.0 to 25.0pmol/I(picomoles per litre)|
|T3||3.5 to 7.8pmol/I(picomoles per litre)|
How to maintain normal thyroid levels
As we have seen that thyroid is one of the important elements that is required for the proper development of the body.
Now the question is how to maintain the normal thyroid levels in our body? What are the efficient and natural ways to do so? Well here are some of the most trusted and workable ways inked down below:
- Get tested and diagnosed on regular basis– You should always go for the regular checkup and you should know the level of iodine, vitamin D and selenium in your body.
If there are any deficiency of these nutrients in your body then you need to take necessary steps to replenish it.
- Use natural herbs– There are lots of natural herbs that can trigger the thyroid boost in your systems such as ashwagandha, coleus forkohlii, sage and bacopa monnieri.
When these herbs are all together combined with iodine and selenium they can help a lot in boosting thyroid.
- Consume balanced diet along with supplements– If you need to boost up the production of thyroid levels in your body then you need to consume whole food which is rich in all the nutrients.
But sometimes it becomes difficult to get all the nutrients in food, so, in that case, to fill the gaps of nutrients we take the help of supplements.
High-quality multivitamins and some of the mineral supplements can help you out of this, as this will also boost your metabolism rate of the body too.
- Avoid stress– Stress is the biggest enemy of the thyroid levels in your body, as stress leads to the formation of cortisol in your body which eventually leads to hypothyroidism.
One of the best ways to avoid stress is to eat good and more, studies have found that 3 good balanced diet food and 2 snacks can help in the smooth working of thyroid glands.
Exercising regularly, having some good sleep and some of the relaxation techniques such as yoga and meditation can help you to get out of stress.
- Always enjoy your meals– Never ever hurry while eating, be relaxed while eating as our digestive system works well when we are relaxed not in hurry.
As it not only helps in good digestion of food but also in relieving stress from you.
Spend time with your family members, friends, and close ones, laugh, sit and spend some quality time with them you will surely see the difference in you and in the thyroid levels too.
Medicines to low thyroid levels
- Potassium iodide
- Sodium iodide
- I3odine Max
- Iodine/potassium iodide
Hence, there are some of the above-mentioned medicines which are effective in lowering the thyroid levels.
Home remedies for low thyroid levels
- Apple cider vinegar– It helps in regulating the hormones and to improve the metabolism rate of the body.
- Fish oil – it is always considered for increasing the thyroid level and also maintaining healthy thyroid function.
- Coconut oil– It contains the fatty acids which help in improving the metabolism rate as well.
- Ginger– it contains zinc, magnesium, and potassium, and these three ingredients are always important for the hypothyroidism.
- Vitamin B– it is one of the most important for the lower thyroid levels so better take an adequate level of B1, B2, B3, B5, B6, B7, B9, and B12.
Thyroid levels during various thyroid disorders
Basically, there is two common thyroid disorder which is as follows :
Hypothyroidism – You are considered to be underactive if the TSH level is above normal, your doctor may determine you as hypothyroid.
If the test result of total thyroxine and the normal range of thyroid levels is between 4.5 to 12.5, and if you have a low reading then this scale and at the same time high TSH level then you are also hypothyroid.
If the reading of the test called free thyroxine is less than 0.7 whereas the normal range is 0.7 to 2.0, in that case also your are hypothyroid.
If the test result of total T3 is less than 80 and the normal range is 80 to 220 and if the result of free T3 shows the reading less than 2.3 whereas the normal range was 2.3 to 4.2, in these cases also you will be termed as hyperthyroid.
Hyperthyroidism– All the same tests are being run for the overactive part of the thyroid glands same as the underactive counterpart.
But the only difference is it just acts opposite of the above tests as if the reading of below normal in the TSH level you will be considered as overactive or hyperthyroid.
If the readings of total thyroxine test is above 4.5 to 12.5, reading of free thyroxine is more than the range of 0.7 to 2.0, results of total T3 is more than 80 to 120, results of free T3 is more than 2.3 to 4.2 then in all the above cases you will be termed as hyperthyroid. Thus, it becomes very essential to keep a check on your body’s thyroid levels to stay healthy and Young.
