Thyroid Disease: TRH Stimulation Test
If you have unexplained…
Chills, fatigue, hair loss, cold feet, cold hands, brain fog, depression, hot flashes, constipation, nervousness, mood swings, loss of appetite, anxiety attacks, weight changes, irregular heart rate, decreased energy, high blood pressure, blight burning sensations, side effects from your meds
…then your thyroid might be trying to tell you something.
Any one or a combination of the above could mean that your thyroid is not producing enough thyroid hormone, which is called hypothyroidism.
Yes, any one of these can mean anything, (and for you women, these even sound like menopause, don’t they?), but if you have tried just about everything out there, and you are still a medical mess, your thyroid could be trying to whisper something in your ear.
What Types Of Hypothyroidism Are There?
The most common cause of hypothyroidism is inflammation of the thyroid gland, which damages the gland’s cells.
Autoimmune or Hashimoto’s thyroiditis, in which the immune system attacks the thyroid gland, is the most common example of this.
Some women develop hypothyroidism after pregnancy (often referred to as “postpartum thyroiditis”).
Other common causes of hypothyroidism include:
- Congenital (birth) defects
- Radiation treatments to the neck to treat different cancers, which may also damage the thyroid gland
- Radioactive iodine used to treat an overactive thyroid (hyperthyroidism)
- Surgical removal of part or all of the thyroid gland, done to treat otherthyroid problems
- Viral thyroiditis, which may cause hyperthyroidism and is often followed by temporary or permanent hypothyroidism
Certain drugs can cause hypothyroidism, including:
- Drugs used for hyperthyroidism (overactive thyroid), such as propylthiouracil (PTU) and methimazole
- Radiation to the brain
- Sheehan syndrome, a condition that may occur in a woman who bleeds severely during pregnancy or childbirth and causes destruction of the pituitary gland
What Should I Look For When Testing Thyroid?
If not, consider having this done, rather than the traditional Thyroid Stimulating Hormone (TSH) test.
The TRH test is a much more accurate test that will tell you:” yes, you are right, you do indeed have a low thyroid.”
Many times the traditional TSH test will tell your doctor that your thyroid level is fine, when it really isn’t!
Basically, a TSH test is just a simple blood test – and many times it is inaccurate.
The TSH test measures the serum levels of thyroid related hormones. This is a static test because it measures the hormones at the instant in time that the blood is drawn.
But, as an endocrine regulatory organ, hormone levels are constantly changing as the body requires. In fact, the hallmark of endocrine health is the ability to change hormone levels for moment to moment physiologic needs.
With a static blood test, we do not know if the results represent the usual state of the hormone levels.
Depending on the timing of the tests, the health condition of the individual at the time, or even psychological stressors, one may miss significant underlying imbalances.
How Does The TRH Test Work?
The TRH Stimulation Test, however, is a much more sensitive test because it evaluates how well the hypothalamus, pituitary and thyroid glands are functioning and communicating together at the same time, and in in real time.
- Begins by baseline thyroid and pituitary hormone levels being drawn.
- Then you are given an injection of a tiny amount of thyrotropin releasing hormone, which stimulates the pituitary to release TSH, a hormone which signals the thyroid to release thyroxine, the main thyroid hormone.
- A second blood sample is drawn 20 to 30 minutes later, and the TSH level is retested. Low thyroid conditions will result in an exaggerated response, and excessive thyroid function and pituitary insufficiency states will result in a depressed response.
Ask for that TRH test!
Now, to better understand the thyroid itself…
…so you can see if there could be a connection between it and the way you are feeling right now, let’s start with some of the most asked questions.
What Does The Thyroid Do?
Your thyroid gland is in your neck, just below your Adam’s apple. It’s fairly flat, so you normally can’t feel it, unless there’s a problem.
To make this less complicated, the main job of your thyroid is to put out a hormone to control your metabolism.
Think of your thyroid putting out hormones as a car that needs gas to run. Gas gets burned in the engine, which ultimately turns the wheels of the car so you can drive over here to see us at the Salerno Center.
The speed of the car depends on how much gas is let in the engine to be burned. The more gas, the more the engine revs. The carburetor, or the fuel injectors, are the parts of the car that control the amount of gas going to the engine, telling the engine how high to rev.
In the same way, the body needs fuel for you to do things, like getting out of your car to yell at the other driver (ok, maybe not that).
It also needs energy to keep the heart beating, the lungs breathing, and the spleen, well, spleening away. The burning of energy to do all of these things is called the – metabolism.
Thyroid hormone is much like the carburetor. Low thyroid hormone levels make the body burn less energy, whereas high levels make the body burn more energy.
Now, we know what some of you are thinking…that does NOT mean that high thyroid levels help you run faster! Oh, don’t you wish.
But it does mean that people with overactive thyroid glands tend to have:
- Higher heart rates
- Muscle shakes
- Lose weight without explanation
This is called hyperthyroidism.
People with under-active thyroid glands, on the other hand, have:
- Slower heart rates
- Fatigued (“chronic fatigue syndrome”)
- Weight gain
That is called hypothyroidism.
Children use much of their energy to grow, so children with hypothyroidism don’t grow well.
Well, some doctors do give extra thyroid hormone supplements to help people lose weight, but that is a big mistake because hyperthyroidism is actually more dangerous than hypothyroidism. Besides, what do you think the pituitary gland does when you take extra thyroid hormone? It lowers the TSH, which makes the thyroid gland put out less of its own hormones.
What Are Hormones And What Do They Do?
Hormones are a liquid chemical that are produced by glands. Much like sweat secreting from our pores, the hormones secrete from these glands.
They drip, if you will, into the bloodstream where they travel to the distant tissues and organs, where they then bind to the tissues’ and organs’ specific cell sites called receptors.
By binding to receptors, hormones send messages (commands, if you will) to your body to do certain functions, to keep itself healthy:
- Stimulation or inhibition of growth
- Mood swings
- Cells in our skin, hair, nails, organs
- Induction or suppression of apoptosis (programmed cell death)
- Activation or inhibition of the immune system
- Regulation of metabolism
- Preparation of the body for mating, fighting, fleeing, and other activity
- Preparation of the body for a new phase of life, such as puberty, parenting, and menopause
- Control of the reproductive cycle
- Hunger cravings
- Sexual arousal
Simply put, think of hormones as the “prime movers” of your physical and mental well-being.
Every time you:
- Get angry
- Become tired
- Have sex
- Wake up
- Feel hungry
- Fall asleep
your body is responding to hormones.
That’s because hormone levels can impact virtually every major system and organ in your body.
Why Choose Dr. Salerno?
Many of you already know how hard it is to find a good doctor: One who will listen to you without thinking it’s all in your head. One who thinks outside the box in figuring out what exactly is wrong with you. One who will not give up on you after just so many visits…
In fact, Dr. Salerno asks all his patients the following questions, especially if you feel you’ve already adopted a healthy lifestyle.
Questions such as:
- Are my symptoms consistent with having a bad thyroid?
- Could my symptoms be the result of anything else?
- What investigations do I need to have performed to make a diagnosis?
- How safe are these investigative tests and procedures?
- If I do have thyroid disease, how do we treat it?
- If I need medications, what are the potential side effects?
- If I need medication, is there any special way I should be taking it?
- Do we need to monitor blood levels for thyroid function? If so, how often?
- Do you do a TRH test?
- Do you have any information on alternative methods, like diet and supplements?
Quick Health Fact!
Did you know that adding to many cruciferous vegetables, such as broccoli, and soy products, to your diet can exacerbate thyroid problems? Fortunately, Dr. Salerno can put together an effective diet program that’s easy to follow, and sure to give you the results you’re looking for.
Thyroid Treatment Diet & Lifestyle Changes
- Food is an important factor in the health of the thyroid gland. Normalizing blood sugar, maintaining healthy lipid levels, and building up your immune system are critical for optimum thyroid function.
- If your diet consists of mostly grains, please try and eliminate them as much as possible. Gluten and many other food sensitivities can cause high levels of inflammation in the gut and are extremely difficult to digest, which can lead to autoimmune issues, leaky gut syndrome, and complications of the thyroid.
- Coconut oil, which happens to be a great source of saturated fat and medium chain triglycerides (MCTs), is an excellent source of energy needed for healthy hormone production.
- Since the adrenals and the thyroid gland are linked together, its important to minimize exposure. Chronic stress, which increases cortisol and adrenalin, creates hormone havoc. When the body is kept in a state of “fight or flight” for long periods of time, it can spawn other negative symptoms as well, such as high blood pressure, blood sugar imbalances, obesity, and high cholesterol.
- Many sea vegetables are rich in iodine and other essential minerals for healthy thyroid function, such as wakame, hijiki, dulse, and nori.
- Hormones are made from fat, so if you don’t eat fresh, organic fish, try taking an Omega-3 supplement – but just make sure it is molecularly distilled and tested for purity.
- If you haven’t already done so, purchase a high-grade, quality air filter. Since toxins can be found throughout our home environment, which is where we sleep, eat, and spend countless hours in – its important to minimize all exposure. The same can be said for water as well, which you drink, bathe, and wash in.
- Exercise, which has an excellent effect on the health of the thyroid, is important for lowering stress, maintaining a healthy weight, and aiding in detoxification.
At Home Self-Help Thyroid Check
This simple at home self-help thyroid check may help identify if your thyroid is trying to tell you something – a possibly good sign that you may need further examination by a doctor.
- Hold the mirror so that you can see the area of your neck just below the Adam’s apple and right above the collarbone. This is the general location of your thyroid gland.
- Tip your head back, while keeping this view of your neck and thyroid area in your mirror.
- Take a drink of water and swallow.
- As you swallow, look at your neck. Watch carefully for any bulges, enlargement, protrusions, or unusual appearances in this area when you swallow.
- Repeat this process several times.
- If you see any bulges, protrusions, lumps or anything that appears unusual, see your doctor right away. You may have an enlarged thyroid, or a thyroid nodule, and your thyroid should be evaluated.
Your thyroid could be trying to tell you something – listen!
