Thyroid 101: Hypothyroidism And Hyperthyroidism

High TSH Levels: What Should You Do?

More than 20 million Americans have thyroid disease, but 60% don’t know it. A Michigan Medicine endocrinologist discusses who’s at risk, signs to look for and how to seek treatment.

Theres a small, butterfly shaped gland in your lower neck, the thyroid, that secretes hormones and affects almost every organ in the body, regulating metabolic processes and controlling body temperature.

When the thyroid doesnt produce a normal hormone level, either not enough or too much, thyroid disease occurs. And according to Michigan Medicine endocrinologist its actually more common than heart disease or diabetes.

An estimated 20 million Americans have some form of thyroid disease, but up to 60% of those that have it are unaware of the condition, according to the American Thyroid Association, with autoimmune diseases like Hashimotos disease and Graves disease among the most common culprits of hypothyroidism and hyperthyroidism, respectively.

If the thyroid hormone levels are too low, referred to as hypothyroidism or underactive thyroid, the brains pituitary gland will produce more thyroid stimulating hormone . TSH prompts the thyroid to make more thyroid hormones in response to low levels.

What Is The Thyroid

The thyroid gland is a small organ thats located in the front of the neck, wrapped around the windpipe . Its shaped like a butterfly, smaller in the middle with two wide wings that extend around the side of your throat. The thyroid is a gland. You have glands throughout your body, where they create and release substances that help your body do a specific thing. Your thyroid makes hormones that help control many vital functions of your body.

When your thyroid doesnt work properly, it can impact your entire body. If your body makes too much thyroid hormone, you can develop a condition called hyperthyroidism. If your body makes too little thyroid hormone, its called hypothyroidism. Both conditions are serious and need to be treated by your healthcare provider.

How Is Thyroid Disease Treated

Your healthcare providers goal is to return your thyroid hormone levels to normal. This can be done in a variety of ways and each specific treatment will depend on the cause of your thyroid condition.

If you have high levels of thyroid hormones , treatment options can include:

  • Anti-thyroid drugs : These are medications that stop your thyroid from making hormones.
  • Radioactive iodine: This treatment damages the cells of your thyroid, preventing it from making high levels of thyroid hormones.
  • Beta blockers: These medications dont change the amount of hormones in your body, but they help control your symptoms.
  • Surgery: A more permanent form of treatment, your healthcare provider may surgically remove your thyroid . This will stop it from creating hormones. However, you will need to take thyroid replacement hormones for the rest of your life.

If you have low levels of thyroid hormones , the main treatment option is:

  • Thyroid replacement medication: This drug is a synthetic way to add thyroid hormones back into your body. One drug thats commonly used is called levothyroxine. By using a medication, you can control thyroid disease and live a normal life.

What Therapies Treat Shaky Hands

Your doctor may recommend one or more lifestyle changes as a way to possibly help ease the symptoms of essential tremor. Suggestions may include to:

  • Use heavier objects. You may need to replace lightweight or delicate objects, such as glasses, silverware, or plates, with heavier versions. The extra weight may make the item easier to handle.
  • Use specially designed utensils and tools. Gripping and controlling pens, pencils, garden tools, and kitchen utensils may be difficult if you have shaky hands. You may need to seek out versions of these items that are designed for individuals with grip and control issues. For example, there are many adaptive utensil options available on .
  • Wear wrist weights. The extra weight on your arm may make control easier. Find a great selection of wrist weights here.

Controversy Over Optimal Tsh

Affordable Blood Test TSH Cost at $39

While most laboratories define a normal TSH as between roughly 0.5 mU/l and 5.0 mU/l, some experts argue that the upper limit of a normal TSH should be loweraround 2.5 mU/l.

The reasoning behind this is that the vast majority of adults without thyroid disease have a TSH value between 0.45 and 4.12 mU/l.

In addition, some physicians believe older patients should have a TSH level that is greater than 4.0 mU/l or 5.0 mU/l, since TSH normally increases with age.

Doctors can avoid some of this controversy simply by looking at each person as an individual. For example, a person who still has significant symptoms of hypothyroidism at a TSH of 4.0 mU/l may do better with a goal TSH of around 1.0 mU/l.

In contrast, someone who has health riskssuch as heart disease or osteoporosismay benefit from having a goal TSH that is higher, perhaps around 5.0 mU/l or 6.0 mU/l.

In pregnancy, TSH should not be allowed to rise above 3.0 mU/l for the health of both the baby and mother.

Conventional Treatment Approaches To Addressing These Thyroid Gland Disorders

Pharmaceutical treatment options are available to assist with the treatment of both Hypothyroidism and Hyperthyroidism. The particular treatment option administered to a patient depends on the particular Thyroid disorder they are suffering from, as well as the severity of their condition. Additional factors may also be taken into account, such as gender, age and weight.

Hot Flashes: Is Your Thyroid Causing This Symptom

Hot flashes are symptoms often associated with menopause1.

It is often one of the very first symptoms that a woman experience when she is starting to go through menopause.

Hot flashes tend to become uncomfortable and inconvenient, not only causing embarrassing moments for a woman in public, but also leading to interruptions in her sleeping schedule.

Even though usually associated with menopause, often thought to be brought on by the fluctuations in estrogen levels among women who are going through this phase in life, it should be noted that there are other health concerns that may also lead to similar physiological effects that cause hot flashes as a symptom.

Additionally, it is important to note that some men have also reported experiencing hot flashes, which can obviously not be brought on as a menopausal symptom. For this reason, investigating additional causes for hot flashes may yield appropriate methods for implementing more effective treatment measures among patients suffering these symptoms.

The main purpose of this post is to examine how the thyroid is connected to hot flashes as a symptom.

Hot flashes are considered an official symptom of certain problems that may develop with the thyroid, and may occur in both men and women.

We will also consider additional factors that may influence the risk of the development of hot flashes.

What You Should Now About Testing Iodine Levels

What I do and suggest from time to time with my patients is testing urinary iodine concentrations.

If you are an adult and your urinary Iodine levels are >300 micrograms this is considered excessive iodine intake.

If you are pregnant, urinary Iodine levels >500 micrograms is considered excessive iodine intake

So my word of caution here is that anyone with thyroid problems or even symptoms of thyroid disease think twice about eating foods high in salt, or supplements that contain Iodine.

So a quick recap, so far I covered 3 of the 5 causes of a high TSH.

number one, I talked about Hashimotos being a cause of elevated TSH, I talked about ;high Cortisol levels and being locked in that Fight or Flight response causing high TSH that was number two, I also talked about excess Iodine causing High TSH being #3

When Tsh Alone Is Not Enough

How High Reverse T3 Causes Low Thyroid Symptoms. Dr Hagmeyer

During diagnosis, most doctors use the TSH test to evaluate thyroid function and determine the optimal course of treatment. There are times, however, when knowing one’s TSH may be insufficient.

For instance, free T4 in addition to TSH is usually tested if a doctor suspects thyroid dysfunction due to disease of the pituitary gland or hypothalamus.

Likewise,;if the TSH is normal, but a person still has symptoms of being hyperthyroid or hypothyroid, free T4 may be checked.

TSH is also not necessarily sufficient to monitor hypothyroidism during pregnancy; T4 and free T4 are often recommended.

Depending on the clinical situation, other thyroid tests that may be done include triiodothyronine , free T3, reverse T3, and thyroid antibody tests.

What Are The Treatments For Hyperthyroidism

The main aim of treatment of an overactive thyroid gland is to reduce your level of thyroxine to normal. Other problems, such as a large thyroid swelling or associated eye problems, may also need treatment. Factors such as the underlying cause of the problem, your age and the size of any goitre are taken into account to decide on the best treatment plan.

Treatment options include the following:

High Tsh But Normal Free T4

What does it mean if your TSH levels are too high but you have normal FT4?

The journal American Family Physician says that levels of TSH over 4.0 mIU/L and free T4 levels within the normal range could be an indicator of subclinical hypothyroidism. This means that a person is at risk of developing hypothyroidism but is not yet showing any noticeable symptoms.12

When To See A Gp

See a GP if you have symptoms of an overactive thyroid.

They’ll ask about;your symptoms and if they think you might have a thyroid problem, they can arrange for a blood test to check how well your thyroid is working.

If the blood test shows that you have an overactive thyroid, you may be referred for further tests to identify the cause.

What Is A T4 Test

Thyroid Disease

T4 Tests A;Total T4;test measures the bound and free thyroxine hormone in the blood. A;Free T4;measures what is not bound and able to freely enter and affect the body tissues.

What does it mean if T4 levels are abnormal? Importantly, Total T4 levels are affected by medications and medical conditions that change thyroid hormone binding proteins. Estrogen, oral contraceptive pills, pregnancy, liver disease, and hepatitis C virus infection are common causes of increased thyroid hormone binding proteins and will result in a high Total T4. Testosterone or androgens and anabolic steroids are common causes of thyroid hormone binding proteins and will result in a low Total T4.

In some circumstances, like pregnancy, a person may have normal thyroid function but Total T4 levels outside of the normal reference range. Tests measuring free T4 either a free T4 or free T4 index may more accurately reflect how the thyroid gland is functioning in these circumstances. An endocrinologist can determine when thyroid disease is present in the context of abnormal thyroid binding proteins.

How Long Does It Take To Recover From Thyroid Surgery

It will take your body a few weeks to recover after your thyroid is surgically removed . During this time you should avoid a few things, including:

  • Submerging your incision under water.
  • Lifting an object thats heavier than 15 pounds.
  • Doing more than light exercise.

This generally lasts for about two weeks. After that, you can return to your normal activities.

How Is Thyroid Stimulating Hormone Controlled

When thyroid stimulating hormone binds to the receptor on the thyroid cells, this causes these cells to produce thyroxine and triiodothyronine and release them into the bloodstream.;These hormones have a negative effect on the pituitary gland and stop the production of thyroid stimulating hormone if the levels of thyroxine and triiodothyronine are too high.;They also switch off production of a hormone called thyrotropin-releasing hormone.;This hormone is produced by the hypothalamus and it also stimulates the pituitary gland to make thyroid stimulating hormone.;

How Much Does The Test Cost

The cost of a TSH test will vary depending upon factors such as where it is performed and whether or not you have insurance coverage. Insurance will usually cover the cost of TSH testing if your doctor orders it to diagnose or treat a medical condition. You can check with your doctor, the lab, or your insurance company to learn more about the cost and what, if any, out-of-pocket costs you may be responsible for.

What You Can Do To Get Healthy Thyroid Hormone Levels

Hidden Cause #23 Why You STILL Have Low Thyroid Symptoms – High Homocysteine

After all this thyroid-hormone-levels-gone-wrong talk, youâd be justified in thinking to yourself, âOkay, so how can I get healthy thyroid hormone levels to help avoid a thyroid problem?â

First, make sure youâre getting the right amount of iodine in your diet .

For men and non-pregnant women, the recommended daily allowance for iodine is 150 micrograms . For pregnant women, that number rises to 220 mcg per day â and 290 mcg a day for women who are breastfeeding.

If you want to check if you have an underactive thyroid gland âor if youâre interested in finding out if you have high thyroid levelsâgetting a thyroid function test can be a good place to start.

Of course, if your thyroid hormone level isn’t within a normal range and you may have a thyroid dysfunction, consult with your healthcare provider to learn what solution is best for you to help get your hormone levels back in balance . If you do have a thyroid disorder or thyroid condition, your healthcare provider may recommend ongoing thyroid testing to monitor results of your treatment plan.

Normal T3 And T4 Levels

What are normal T3 and T4 levels when your thyroid is functioning properly?

Dr. Jayita Poduval who specializes in neck and throat disorders says that normal free T3 levels are 125 250 ng/dL in children and 80 200 ng/dL in adults.21

The reference range for free T4 is 0.7 1 ng/dL in adults and 0.8 2 ng/dL in children and adolescents.22

Definition Of A High Tsh

So what defines a “high” TSH?

If your TSH is higher than 5.0 then the lab will flag you as “high” and you may experience the symptoms listed above.;

You can see a clear example of this below:;

The reference range in this example is 0.3 to 5.00 uIU/ml and the result is 7.024.;

Having said all of this, there’s actually a good case to make that you can still have a “high” TSH but still be inside of the reference range.;

So how do we get there?

Well, newer studies have shed light on the fact that some of the original tests that helped determine our “standard normal” TSH values may not have have been full of “healthy” people.;

When you are being compared to some standard you want to make sure that the standard you are being compared to is actually healthy!

It doesn’t make sense to compare your TSH as a 25-year-old to that of an 86-year-old .

Using this logic some newer studies have suggested that a more “normal” TSH reference range is somewhere between 1.0 and 2.5 uIU/ml and anything higher than 2.5 is considered “high” .

With this logic you can have a “high” TSH anywhere between 2.5 and 5.5, even though it technically falls within the “normal” range:;

In addition, other studies have suggested we use the African American population as the standard for TSH testing because they have one of the lowest rates of autoimmune disease compared to other populations and their TSH is somewhere around 1.0.;

How To Keep Hypothyroidism Under Control

Because youll need to take thyroid medication every day for the rest of your life, even after the right dose is found, your hormone levels will be monitored regularly to be sure that your treatment is working properly. Eventually, most people with hypothyroidism can just be seen yearly by their doctor, Doria-Medina says.

The American Thyroid Association recommends that you keep your TSH within a narrow range of 0.5 to 2.5 mU/L, but dont be alarmed if your test results vary a little. Some variation is normal because your pituitary gland sends out TSH in pulses, not a steady stream. Also, factors like the time of day youre tested can make a difference. TSH levels are likely to be higher at night and lower during the day. Some people, including those who are pregnant or those with a history of thyroid cancer, have different TSH goals. Talk to your doctor about the target TSH range thats right for you.

If you have new or worsening symptoms or your health status changes such as if you become pregnant, go through menopause, or are given another medicine that can interfere with the absorption of your thyroid hormones, such as anticonvulsants, certain antacids, or iron or calcium supplements you should see your doctor and have your blood tested again, even if its ahead of schedule.

Thyroid Hormone Level Tests

Optimal TSH T3 & T4 levels

There are four main thyroid hormones that have been identified: T1, T2, T3 and T4.

T4 and T3 are the two main thyroid hormones. T4 is known as prohormone and is 300 percent less biologically active than T3. T3 is the main biologically active thyroid hormone and gives us beautiful hair, replenishes our energy, and runs our metabolism.

You may have put together that most of the commonly prescribed thyroid medications like Synthroid and levothyroxine, only contain T4 , and thus they need to be converted to the active T3 form in the body.

On paper, the T4 to T3 conversion happens just fine, but in the real world, in real human bodies, we may not always convert T4 to T3.

We can reveal our T4 to T3 ratios and measure the hormone that is available to do its job in the body, by testing our free T4 and free T3 levels.

Free T3 and Free T4 tests measure the levels of active thyroid hormone circulating in the body.

Some clinicians may only test for T4, but T3 is also important to test, as some individuals may not be converting T4 to the active T3 properly. Thus, people may have a normal T4, but a low T3 level.

How Do You Know If You Are Converting Correctly?

Take a look at your free T3 and free T4 levels. Both should be in the optimal range. If the T4 is optimal, but the T3 is out of the optimal range, you know that your body is not making enough T3 hormone from the T4.

Optimal T4 reference range: 15-23 pmol/L

Optimal T3 reference range: 5-7 pmol/L
