Episode 25 – How to Test Your Thyroid for Hypothyroidism

A blood draw is a routine, minimally invasive procedure. During the days immediately after the blood draw, you may notice slight bruising or soreness at the area where the needle was inserted. An ice pack or an over-the-counter pain reliever can help ease your discomfort.

If you experience a great deal of pain, or if the area around the puncture becomes red and swollen, follow up with your doctor immediately. These could be signs of an infection.

Thyroid Disorders And Symptoms

Underactive thyroid

If you dont produce enough thyroid hormones your bodily processes start to slow down. Signs of an underactive thyroid include:

  • tiredness

Autoimmune thyroid diseases An autoimmune disease is when your immune system mistakenly attacks your body in this case, thyroid antibodies attack your thyroid. This can lead to a thyroid disorder. Types of autoimmune thyroid diseases include Graves disease or Hashimotos disease .

Thyroid Nodules Are Usually Benign And Not Cancerous

The good news is that most people with thyroid nodules do not and will not get thyroid cancer.

The bad news is that a thyroid nodule is not normal and may be associated with other conditions of your thyroid gland.

So, even if you don’t have thyroid cancer, you should still have your thyroid nodule evaluated and tested for other conditions which are associated with thyroid nodules.

Conditions in this category include:

It’s important to realize that many thyroid nodules are just run-of-the-mill nodules which are not associated with thyroid disease of any kind.

But, in order to be on the safe side, it’s ideal that every patient who has a thyroid nodule undergoes certain tests to ensure that this is the case.

Tests such as a comprehensive history and physical, palpation of the thyroid gland, tests of your thyroid function through blood work, and even an ultrasound may all be warranted.

Your doctor should be walking you through these steps but you can also ask for them if you are worried.

Signs You Should Get Your Thyroid Checked

When to do a Thyroid Profile Test?

One tiny gland in your body that weighs under one ounce can put you into a world of hurt if it is not working correctly. That would be the thyroid gland. The Mayo Clinic notes that your thyroid “is located at the base of your neck, just below the Adam’s apple.” The gland contains hormones that regulate multiple functions in your body, including your metabolism, heart rate, and body temperature. So if it malfunctions, you can have a variety of health issues.

There are two basic ways your thyroid gland can go awry, according to hyperthyroidism, in which the gland produces too much thyroid hormone, and hypothyroidism, in which it produces too little. These disorders can be caused by a variety of issues and are more common in women than in men, according to the U.S. Department of Health and Human Services.

Here are the symptoms you should watch out for that can show that the gland is overactive or underactive.

What Is Being Tested

Thyroid function tests are used to check for a number of thyroid problems. The tests measure the amount of different hormones including thyroid stimulating hormone , thyroxine , and triiodothyronine . Other tests on the thyroid include various antibodies related to thyroid tissue.

TSH is produced by the pituitary gland in the brain. TSH is carried in the blood to the thyroid gland, which sits at the front of the neck. From there, TSH influences how much T4 and T3 are released into the blood.

TSH, T3 and T4 levels can all be tested in the blood. Your doctor will probably test TSH first, then T3 and T4 if TSH is abnormal. Tests can also be used to measure antibodies to diagnose autoimmune thyroid disease.

Thyroid Nodules And Thyroid Cancer

The biggest concern on most people’s mind is probably whether or not their thyroid nodule is actually cancer in disguise.

As I mentioned previously, most thyroid nodules are benign.

But that leaves another 5-10% which can be cancerous and should be evaluated.

There are some factors which have been evaluated which can help you understand your risk of thyroid cancer.

The risk of thyroid cancers increases with these risk factors:

What Is Thyroid Hormone

Thyroid hormone is made by the thyroid gland, a butterfly-shaped endocrine gland normally located in the lower front of the neck. Thyroid hormone is released into the blood where it is carried to all the tissues in the body. It helps the body use energy, stay warm and keeps the brain, heart, muscles, and other organs working as they should.

Thyroid hormone exists in two main forms: thyroxine and triiodothyronine . T4 is the primary form of thyroid hormone circulating in the blood . To exert its effects, T4 is converted to T3 by the removal of an iodine atom this occurs mainly in the liver and in certain tissues where T3 acts, such as in the brain. T3 normally accounts for about 5% of thyroid hormone circulating in the blood.

Most thyroid hormone in the blood is bound by protein, while only a small fraction is “free” to enter tissues and have a biologic effect. Thyroid tests may measure total or free hormone levels.

What Should I Do To Prepare For A Thyroid Function Test

Why Your Doctor Is Wrong About Thyroid Testing

Thyroid function tests usually require very little preparation.

You don’t need to fast before the blood test. And it doesn’t matter if you have taken your thyroid medicine just before the blood test.

Tell your doctor if you are taking any medication, as some medicines can alter the test results and how they are interpreted.

It is also important to mention if you have had any X-ray tests that have used a special contrast dye, as this may contain iodine which can affect the results. Levels of thyroid chemicals also change in pregnancy, so tell your doctor if you are pregnant when the test is taken.

Note: all newborn children have their thyroid function tested as part of the heel prick test which is offered to all babies and undertaken when they are 5 days old. See the separate leaflet called Newborn Baby Screening Tests for more information.

How A Doctor Checks A Thyroid

If you go to your physician about a thyroid issue, chances are they will physically examine your thyroid. But you will also need to get blood tests that break down your thyroid levels. Dr. Block explained to me the TSH Test is what is used to diagnose thyroid issues. It measures these “signals from your pituitary to your thyroid,” but she explained that the TSH levels are “the opposite of what people think.” A high TSH level indicates hypothyroidism and a low level indicated hyperthyroidism.

She said that a “high TSH is seen in hypothyroidism because your brain is yelling at your thyroid to speed up,” while a “low TSH is seen in hyperthyroidism because your pituitary is telling your thyroid to slow down or stop making thyroid hormone.”

Why Having A Correctly Working Thyroid Matters

Since the thyroid regulates so much of our body, it is important to have it working correctly to have optimum health. Dr. Goldfarb told me that when it comes to your thyroid, some “mild thyroid conditions that are not treated for many years can affect your heart, bones, and other organ systems,” but that there are also “very mild abnormalities” that “may go unnoticed and don’t necessarily need to be treated.” She stressed that “symptoms that are caused by very abnormal thyroid hormones can also affect things like your energy level and productivity, which impacts your general health.”

In addition, “for women trying to get pregnant, having your thyroid hormones in normal range is important,” the physician said.

But What If Its Thyroid Cancer

A cancer diagnosis is always worrisome, but even if a nodule turns out to be thyroid cancer, you still have plenty of reasons to be hopeful.

Thyroid cancer is one of the most treatable kinds of cancer. Surgery to remove the gland typically addresses the problem, and recurrences or spread of the cancer cells are both uncommon. People who undergo thyroid gland surgery may need to take thyroid hormone afterward to keep their body chemistry in balance.

Whether its benign or not, a bothersome thyroid nodule can often be successfully managed. Choosing an experienced specialist can mean more options to help personalize your treatment and achieve better results.

Stage : The Breakdown Of The Immune Tolerance

Hypothyroidism  Thyroid Test

In the second stage, you start seeing the breakdown of the thyroids immune tolerance, and the person will start to have a white blood cell infiltration into the thyroid gland. Some of these immune cells are going to start grouping there. This is when we will also start seeing elevated thyroid antibodies. This stage can go on for many years a decade or more before a person moves on to stage 3 or 4, when we start to actually see symptoms and changes in thyroid function.

Whats The Treatment For A Thyroid Nodule

Even a benign growth on your thyroid gland can cause symptoms. If a thyroid nodule is causing voice or swallowing problems, your doctor may recommend treating it with surgery to remove all or part of the thyroid gland.

If the doctor recommends removal of your thyroid , you may not even have to worry about a scar on your neck. Some patients are good candidates for a scarless thyroid procedure, where the surgeon reaches the thyroid through an incision made on the inside of your lower lip.

A newer alternative that the doctor can use to treat benign nodules in an office setting is called radiofrequency ablation . Radiofrequency ablation uses a probe to access the benign nodule under ultrasound guidance, and then treats it with electrical current and heat that shrinks the nodule. Its simple: Most people treated with RFA are back to their normal activities the next day with no problems.

What If You Suspect That You May Have Borderline Or Subclinical Hypothyroidism Which Means You Have High Tsh Hormone Levels But Theyre Not Quite High Enough For Your Doctor To Recommend Treatment Yet

The American College of Endocrinology believes that it is important to listen to every patient, address their concerns and to use both objective and subjective measures to determine whether you will benefit or not from treatment. The medication used for thyroid treatment is very safe and has been around for a very long time, so there is no reason not to get tested and seek treatment if you suspect you may have a thyroid hormonal imbalance. It’s better to get tested and realize it is not a thyroid issue like you thought then to wait and have to deal with the symptoms of a chronic illness that can be easily and safely treated once diagnosed.

We know that cholesterol, blood pressure, heart rate, sleep patterns and menstrual cycles are very objective measures of thyroid function and physiology. If you have things that are not feeling right in those areas, that are part of the syndrome of thyroid disease, you can use those to make your case for trying treatment. If you do that, and you understand the framework that your doctor provides as a reason not to prescribe medication yet, ask for a plan of action like repeated tests. Repeat evaluations and tests ensure that the single point in time that you were tested was not an error. Often, over time, health issues come to light that are not apparent in a single medical visit.

What Are Thyroid Hormones

The thyroid gland produces hormones that are essential for normal body metabolism. Blood testing is now commonly available to determine the adequacy of the levels of thyroid hormones. These blood tests can define whether the thyroid gland’s hormone production is normal, overactive, or underactive.

The thyroid gland is located in the lower part of the neck, below the Adam’s apple.The gland wraps around the windpipe and has a shape that is similar to a butterfly – formed by two wings and attached by a middle part .

The thyroid gland uses iodine to produce thyroid hormones.

  • The two most important thyroid hormones are thyroxine and triiodothyronine , which account for 99.9% and 0.1% of thyroid hormones present in the blood respectively.
  • However, the hormone with the most biological activity is T3.
  • Once released from the thyroid gland into the blood, a large amount of T4 is converted into T3 – the active hormone that affects the metabolism of cells.

What Is The Role Of The Thyroid Gland

The thyroid is located at the front of the neck and consists of two lobes, one on each side of the windpipe and adjoined by a small strip of thyroid tissue known as the isthmus. The three hormones produced by the thyroid are:

  • T3
  • T4
  • Calcitonin

T3 and T4 are the active forms of the thyroid hormone, thyroxine, and are involved in the regulation of:

  • The bodys metabolic rate
  • Heart function
  • Bone maintenance

Treatment Of Thyroid Issues

If hypothyroidism is diagnosed, you will usually begin taking levothyroxine a synthetic, man-made version of the thyroid hormone thyroxine.

If hyperthyroidism is diagnosed, however, treatment options include:

  • Antithyroid Drugs
  • Surgery to remove some of or all the thyroid gland
  • Radioactive iodine to reduce the thyroids activity

As mentioned above, when treatment commences, it is likely you will have blood tests on a regular basis, possibly every few weeks to assess your bodys response to treatment. Once the treatment has made your condition stable, the frequency of the blood tests should reduce.

Your Hands Are Trembling

People think of trembling hands as a sign of Parkinson’s disease, as well as simple nervousness, but it can also be a sign of hyperthyroidism. The Mayo Clinic describes the hand tremors as “usually a fine trembling in your hands and fingers.” When you have a tremor, you may literally find that your hands are shaking. And if the case of trembling is severe, the National Institute of Neurological Disorders and Stroke says that you might have “difficulty writing or drawing” as well as “problems holding and controlling utensils.” You might also find that the trembling gets worse during times of stress.

Your Menstrual Cycle Is Messed Up

Understanding Thyroid Cancer and How It Works  Best In ...

If you are having problems with your period, you may assume that you have issues with your reproductive system. But it could be your thyroid causing those issues, rather than your uterus, ovaries, or fallopian tubes. The Mayo Clinic lists “heavier than normal or irregular menstrual periods” as symptoms of hypothyroidism and “changes in menstrual patterns” as possibly indicating hyperthyroidism.

Dr. Ali told me you may want to get your thyroid checked if you are experiencing menstrual cycle changes, and Dr. Block said that “irregular periods can often represent a thyroid problem, either overactive or underactive.”

What Is Postpartum Thyroiditis

Postpartum thyroiditis is an inflammation of the thyroid that affects about 1 in 20 women during the first year after giving birth1 and is more common in women with type 1 diabetes. The inflammation causes stored thyroid hormone to leak out of your thyroid gland. At first, the leakage raises the hormone levels in your blood, leading to hyperthyroidism. The hyperthyroidism may last up to 3 months. After that, some damage to your thyroid may cause it to become underactive. Your hypothyroidism may last up to a year after your baby is born. However, in some women, hypothyroidism doesnt go away.

Not all women who have postpartum thyroiditis go through both phases. Some only go through the hyperthyroid phase, and some only the hypothyroid phase.
