How Is Goiter Diagnosed
Your healthcare provider usually diagnoses goiter when they perform a physical examination and feel that you have an enlarged thyroid. However, the presence of a goiter indicates that theres an issue with your thyroid gland. Theyll need to figure out what the issue is.
Your provider can use several tests to diagnose and evaluate goiter, including the following:
What To Consider When Searching For An At
In your search for an at-home thyroid test, decide what is most important for your needs. Most tests measure TSH and T4 levels. You may need further tests that measure levels such as T3, T7, TSI, and antibodies. Find out what types of recommendations for additional testing or treatment plans each company offers.
At-home tests can be considered if you have symptoms that cause you to suspect a thyroid disorder. You may also want to test your thyroid levels after implementing lifestyle changes, starting a new medication, or beginning a treatment plan. Its also a good idea to do a home test if you are at risk of developing a thyroid disorder.
At-home thyroid tests offer plenty of advantages and drawbacks to consider.
Signs You Should Get Your Thyroid Checked
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 EndocrineWeb.com: 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.

Why Is Thyroid Health Important
The thyroid is paramount because the thyroid hormone affects all cells and all tissues in the body by maintaining normal metabolism. Humans cannot live without a thyroid hormone. When your thyroid is unhealthy, a few things may occur.
When thyroid hormone levels are low, also called hypothyroidism, all metabolic processes in your body slow down, explains naturopathic physician Andrew Neville, N.D. Many people with hypothyroidism experiencefatigue, constipation, weight gain, hair loss, and depression. An underactive thyroid is one of the most common thyroid conditions, affecting 5% of the global population1.
Hyperthyroidism is on the other end of the spectrum. It occurs when the thyroid is hyperactive and produces too many thyroid hormones. This speeds up your metabolism and can cause symptoms like rapid weight loss, irregular heart beats, and sweating.
The Thyroid Screening Test
The thyroid stimulating hormone, or TSH test, is used as a screening test for thyroid disease, as well as a test for monitoring the correct dose of medication needed for an individual.
This is an important test that I recommend getting every time you check your thyroid function.
TSH is a pituitary hormone that responds to low/high amounts of circulating thyroid hormone. If youre new to thyroid lab testing, it may seem counterintuitive, but an elevated TSH means that you do not have enough thyroid hormone on board and that you are hypothyroid. This is because the TSH hormone senses low thyroid levels and is released when there is a lack of it, in an effort to signal the body to make more.
In advanced cases of Hashimotos and primary hypothyroidism, this lab test will be elevated. In the case of Graves disease and hyperthyroidism, TSH levels will be low. People with Hashimotos and mild or central hypothyroidism may have a normal reading on this test.
If youve been a thyroid patient for a while, youre probably thinking to yourself, Well, of course, doesnt everyone know that? and I have to warn you Ive unfortunately seen physicians who have mistakenly thought that a low TSH meant one had an underactive thyroid, and a high TSH, an overactive thyroid putting their patients in really dangerous situations by under- or overmedicating them!
Most conventional practitioners will stop further thyroid testing when they determine the TSH is normal .

You Have Depression Memory Issues Nervousness Or Irritability
This is one of the most frustrating things about not being diagnosed with a thyroid issue. You may be depressed, have memory issues, or be annoyed or panicky all the time, and you think it’s psychological instead of physical. Dr. Romy Block, a Chicago-area endocrinologist, told me that “mood changes ” can indicate that your thyroid is out of whack. The Mayo Clinic cites depression as a symptom of hypothyroidism, but it can also manifest in hyperthyroidism, as one counselor wrote in Psychology Today, and as a patient case study on the National Center for Biotechnology Information’s website shows.
Other things to look out for include “nervousness, anxiety and irritability,” which the Mayo Clinic says may be a sign of hyperthyroidism. And Dr. Block told me that “a common symptom of hypothyroidism is memory loss,” so if you feel like you’re being too forgetful these days, there might be a reason.
Hypothyroidism Caused By Dieting
Many people dont realize this but dieting has a profound negative impact on thyroid function!
We know this from starvation studies but Ive also had the advantage of testing thyroid function in patients who have just recently undergone extreme dietary restrictions from things like the hCG diet.
And when I tested these patients, their thyroid lab patterns look just like hypothyroidism.
They show very high levels of reverse t3, low t3, and changes to their TSH. These changes to thyroid function result as your metabolism declines in response to your calorie restriction.
The good news is that these changes are temporary, the bad news is that recovery can take years and that during your recovery period, you will look and feel hypothyroid.
If you go to your doctor during this period then you may be diagnosed with hypothyroidism and placed on thyroid medication.

What Tests Will Be Done To Diagnose And Evaluate Thyroid Nodules
Your healthcare provider may order any of the following tests to help diagnose and evaluate a thyroid nodule:
- Thyroid blood test: This test checks the levels of thyroid hormone in your blood. The hormone levels are usually normal even if you have nodules, but they can be abnormal in some cases and point to thyroid disease.
- Thyroid ultrasound: This is an imaging test that uses sound waves to create pictures of your thyroid gland. It can determine if a nodule is solid or a fluid-filled cyst. This test also checks on the growth of nodules and helps find nodules that are difficult to feel. In addition, providers sometimes use ultrasound to help guide the placement of the needle during a fine-needle biopsy.
- Fine-needle biopsy: With this test, your provider uses a very thin needle to take a sample of cells from one or more thyroid nodules. They then send the samples to a laboratory for evaluation. Most nodules are noncancerous. However, if the test results are inconclusive, your provider may repeat this test. They may also suggest you have surgery to remove the nodules to make an accurate diagnosis.
- Thyroid scan: In this test, you take a small amount of radioactive iodine orally. Your provider will check to see how much of the radioactive iodine the thyroid nodules absorb and how much is absorbed by normal thyroid tissue. This will provide further information about the thyroid nodules, helping your provider determine the likelihood of cancer.
What Is Thyroid Disease
Some diseases of the thyroid or pituitary gland cause the thyroid to make too much or not enough thyroid hormone:
- If the thyroid is overactive, it releases too much thyroid hormone, causing . The body use up energy more quickly than it should, and chemical activity in the cells speeds up. Symptoms include sweating, trembling, weight loss, and fast heartbeat.
- If the thyroid is underactive, it makes too little thyroid hormone, causing . The body uses up energy more slowly, and chemical activity in the cells slows down. Symptoms include tiredness, feeling cold, constipation, dry skin, and slow height growth in children.

How Having Hyperthyroidism Changed My Life
In early 2007, I found that I was tired all the time and felt very weak. My muscles seemed to get tired quickly even just walking down the street from my car to my house seemed to wear me out. I also had tremors in my hands, I was hot all the time, even in winter, and my eyesight seemed to be fading.
I chalked some of it up to stress at work but I began to get really scared when even on days off from work, I was still so exhausted. So I went to my primary care physician to see what was going on. He ran a battery of tests, including blood work, on me, and discovered my thyroid numbers were way off, indicating an overactive thyroid.
My physician referred me to an endocrinologist, a doctor who is a specialist in thyroid issues. All it took was him taking literally one look at me, as well as feeling my thyroid nodules in my neck, to figure out that I appeared to have Graves’ Disease, an autoimmune disease that causes hyperthyroidism. He also asked me about how I was feeling. I didn’t have all of the symptoms of hyperthyroidism. For example, my hair didn’t change, and my skin stayed the same. But I had enough of the symptoms to indicate that there was an issue.
Top 10 Thyroid Tests And How To Interpret Them
Medically reviewed and written by Izabella Wentz, PharmD, FASCP
In my clinical experience, Ive seen many cases of thyroid problems go undiagnosed because most doctors dont perform a comprehensive test panel.
I spent almost a decade undiagnosed because I only had one marker tested. My thyroid condition was missed completely, leading me to deal with needless mystery symptoms like chronic fatigue, depression, anxiety, and many others, for far too long!
I still have a copy of my lab results from 2008, before I was diagnosed with Hashimotos. At that time, I was desperately searching for a reason behind my exhaustion, hair loss, anxiety, and digestive issues. According to this lab report, my TSH was at 4.5 IU/mL, yet there was a note written from the doctor declaring: Your thyroid function is normal, no need to do anything. Perhaps a TSH of 4.5 IU/mL would have been normal for a 95-year-old woman, but I was 25 and sleeping 12+ hours a night to feel rested!
Of course, even as a pharmacist, I didnt think to question the doctor and most people dont. If you suspect that you may have a thyroid condition, or know someone who does, this article will go over all of the most helpful tests that can help you identify a thyroid condition.
This article will also teach you how to understand your labs so that you can advocate for proper treatment for yourself.

Magnetic Resonance Imaging Scan
MRI scans use magnets instead of radiation to create detailed cross-sectional images of your body. MRI can be used to look for cancer in the thyroid, or cancer that has spread to nearby or distant parts of the body. But ultrasound is usually the first choice for looking at the thyroid. MRI can provide very detailed images of soft tissues such as the thyroid gland. MRI scans are also very helpful in looking at the brain and spinal cord.
How Should I Prepare For A Thyroid Function Test
Generally, you won’t need to do anything before having this test. It can be done at any time of the day. Some medicines may affect the test so tell your doctor about all prescription and non-prescription medicines you take.If you are taking thyroid medicines, tell your doctor when you took your last dose. Your doctor may ask that you stop taking thyroid medicines temporarily before having this test.

How Does The Thyroid Gland Function
The major thyroid hormone secreted by the thyroid gland is thyroxine, also called T4 because it contains four iodine atoms. To exert its effects, T4 is converted to triiodothyronine 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. The amount of T4 produced by the thyroid gland is controlled by another hormone, which is made in the pituitary gland located at the base of the brain, called thyroid stimulating hormone . The amount of TSH that the pituitary sends into the bloodstream depends on the amount of T4 that the pituitary sees. If the pituitary sees very little T4, then it produces more TSH to tell the thyroid gland to produce more T4. Once the T4 in the bloodstream goes above a certain level, the pituitarys production of TSH is shut off. In fact, the thyroid and pituitary act in many ways like a heater and a thermostat. When the heater is off and it becomes cold, the thermostat reads the temperature and turns on the heater. When the heat rises to an appropriate level, the thermostat senses this and turns off the heater. Thus, the thyroid and the pituitary, like a heater and thermostat, turn on and off. This is illustrated in the figure below.
Side Effects Of Thyroid Blood Tests And Care
Thyroid blood tests are performed after a routine blood draw. Thats when blood is drawn from you by a syringe and sent to a lab. This is a safe procedure with few potential side effects.
Its rare, but some people get nauseous or feel faint when they have blood drawn. Let the medical personnel know immediately if you experience these side effects.
Later, you may notice a small bruise or have some tenderness at the needle insertion site. An over-the-counter pain reliever or an ice pack can help with this.
You should get medical attention if the insertion site is:
These are signs of an infection, which needs to be treated with antibiotics.

Undetected Low Levels Of Thyroid Hormone May Underlie Subtle Changes That Can Increase Your Risk Of Cardiovascular Disease
For a gland only two inches in size, the thyroid has a huge influence on our health. It produces a hormone that is carried in the bloodstream to all parts of the body. Thyroid hormone plays a major role in regulating metabolismthe process by which body cells convert nutrients into energyand thereby helps regulate body temperature, heart rate, and even brain function. So when thyroid hormone levels fall, the body slows.
You’re probably aware of the common symptoms of low thyroid hormonefatigue, fuzzy-headedness, weight gain, cold hands, and dry skin. But if you’re like most of us, you’re likely to blame your diet and exercise regimen instead of your thyroid if your cholesterol levels and weight are creeping up, especially if you don’t have any of the other symptoms of low thyroid. “Symptoms are often nonspecific, and since women over 60 generally have more of these nonspecific symptoms, their doctors may not think to test for hypothyroidism,” says endocrinologist Dr. Jeffrey Garber, associate professor of medicine at Harvard Medical School and author of The Harvard Medical School Guide to Overcoming Thyroid Problems.
Complementary And Alternative Medicine
Some people try other therapies to cleanse the body, restore immune function, and balance the production and release of hormones. You should talk to your doctor if you’re interested in these other methods to make sure they won’t harm you or interfere with your treatment.
A naturopath may use homeopathic mixtures, herbs, preparations based on traditional Chinese medicine , and acupuncture to remove blocks to your ”life force energy.” Naturopaths are authorized to treat thyroid disease in some states, but in others, it’s illegal. While they may help with the stress associated with thyroid disease, there are no good studies showing that these therapies are effective for treating thyroid disorders.
Chiropractors use spinal manipulation to treat symptoms of thyroid disorders by easing muscle tension and improving blood circulation.
