How Is Thyroid Disease Diagnosed
Sometimes, thyroid disease can be difficult to diagnose because the symptoms are easily confused with those of other conditions. You may experience similar symptoms when you are pregnant or aging and you would when developing a thyroid disease. Fortunately, there are tests that can help determine if your symptoms are being caused by a thyroid issue. These tests include:
- Blood tests.
- Physical exams.
One of the most definitive ways to diagnose a thyroid problem is through blood tests. Thyroid blood tests are used to tell if your thyroid gland is functioning properly by measuring the amount of thyroid hormones in your blood. These tests are done by taking blood from a vein in your arm. Thyroid blood tests are used to see if you have:
The specific blood tests that will be done to test your thyroid can include:
These tests alone arent meant to diagnose any illness but may prompt your healthcare provider to do additional testing to evaluate for a possible thyroid disorder.
Additional blood tests might include:
Talk to your healthcare provider about the ranges for these thyroid blood tests. Your ranges might not be the same as someone elses. Thats often alright. If you have any concerns or worries about your blood test results, talk to your provider.
An ultrasound typically takes about 20 to 30 minutes.
Sensitive Skin And Skin Discoloration
Thyroid hormones also influence the quality of your skin in a variety of ways. With hyperthyroidism, you may notice itchy and dry patches of skin.;
Your face may feel softer and swollen. You may even notice swelling around your fingertips. Other symptoms include darkening of the skin, rashes, lumps, and reddish spots.

Weak Nails And Thinning Hair
Your hair and nails are constantly growing. One important function of the thyroid gland is sending hormone signals to trigger hair and nail growth. With hyperthyroidism, the extra hormones tell your body to increase the growth of your hair follicles and nails in a shorter period of time. While it would seem that your nails growing fast would be a positive side effect of thyroid dysfunction, that isnt the case. This forced growth is too fast. As a result, your body has to stretch its natural resources, which can lead to thin and brittle hair and nails.

- What to do about it?
Thyroid nodules that the patient can see, or somebody else can see should almost always be examined by an ultrasound test. Depending on the characteristics of the nodule , the nodule may need a needle biopsy. Almost all thyroid nodules that can be seen should have a FNA thyroid needle biopsy.
Trouble Concentrating Or Remembering
Many patients with hypothyroidism complain of mental fogginess and trouble concentrating. The way this mental fogginess presents itself varies by person.
In one study, 22% of low-thyroid individuals described increased difficulty doing everyday math, 36% described thinking more slowly than usual and 39% reported having a poorer memory .
In another study of 14 men and women with untreated hypothyroidism, the participants showed difficulty remembering verbal cues .
The causes for this are not yet fully understood, but difficulties in memory improve with treatment of low thyroid hormone .
Difficulties in memory or concentration can happen to everyone, but if they are sudden or severe, they could be a signal of hypothyroidism.
Summary: Hypothyroidism can cause mental fogginess and difficulty concentrating. It may also impair certain kinds of memory.

What To Do If You Have A Nodule
Remember, the vast majority of thyroid nodules are benign. The nodule should be evaluated by a physician who is comfortable with this problem. Endocrinologists and thyroid specialist surgeons deal with these problems on a regular basis, but many family practice physicians, general internists, and general surgeons and otolaryngologists are also adept at addressing thyroid nodules.
One of the first things a physician should do is ask two important questions regarding your health and potential thyroid problems. The first question is whether you have been exposed to nuclear radiation or received radiation treatments as a child or teenager.; The second question is whether there is a family history of thyroid cancer or other endocrine conditions.
Thyroid Nodule Symptom # : A Cough That Just Won’t Go Away Frequent Coughing And A Need To Keep Clearing Your Throat
- What to do about it?
Thyroid nodules that cause the patient to cough should always be evaluated with an ultrasound scan. Occasionally a CAT scan is required because it is better at looking at big thyroid goiters than ultrasound is . Sometimes it just can’t be known for sure if the thyroid nodule is actually causing the coughing. Often these patients undergo a laryngoscopy . If the thyroid nodule is causing the coughing, or there is a high liklihood it is the cause, then surgery is indicated. Of course, it is now very important for you to chose your surgeon wisely. The nerves to the vocal cords are occasionally damaged by a surgeon removing a thyroid and this will cause severe horseness and a loss of voice for months or even forever. We have an entire page dedicated to helping you chose a surgeon wisely!

That Lump Feeling In Your Throat Sometimes Isnt Just A Feeling; It Could Be Cancer Acid Reflux Anxiety And Not So Surprisingly Low Or Underactive Thyroid
When the thyroid gland is not producing enough thyroid hormone, it is called hypothyroidism, says Gene Liu, MD, MMM, President, Chair, Department of Surgery; Chief, Division of Otolaryngology, Cedars-Sinai Medical Group.
Patients who are hypothyroid can have a feeling of a lump on the throat, or globus sensation about a third of the time, and is highly dependent on the reason for the hypothyroidism, continues Dr. Liu.
Many hypothyroid patients have underlying inflammation from autoimmune thyroid disease, post-viral episodes or other types of thyroiditis. And this inflammation in the neck can cause the globus sensation.
How well your thyroid is functioning can be determined by a blood test. If you have an underactive thyroid gland, this does not always mean weight gain.
In fact, low thyroid can cause a menagerie of symptoms that most people would never associate with poor function of this so-called master gland.
Yes, it can cause some weight gain, but often, there is none. Instead, an affected individual might have a completely different batch of symptoms other than the ones that get the most media attention, which are weight gain, hair loss or thinning hair, feeling cold when nobody else does and fatigue.
Symptoms Of Thyroid Goiters
Most thyroid goiters don’t cause symptoms, but they will if the goiter continues to grow. In fact, small thyroid goiters may more commonly be detected by routine examination of the patient’s neck by a doctor or by some type of screening x-ray or scan for some other reason. The symptoms occur as the goiter becomes big enough that it presses on other structures in the neck.
Larger thyroid goiters most commonly produce symptoms of
- A mass or lump in the neck.
- Uncomfortable pressure sensation on the breathing tube
- A sense of feeling like you need to swallow something or difficulty swallowing
- Excess production of the thyroid hormone, thyroxine which include:
- Unexplained weight loss
- Rapid or irregular heart rate

How Are Goiters Treated
Depending on the test results, a goiter might not need to be treated. If it does, treating the thyroid disease causing the goiter usually will decrease or control the enlargement.
Surgery might be needed if the thyroid keeps getting bigger even with treatment and causes discomfort or a very large lump in the neck.
Hyperthyroidism Diagnosis And Treatment
A blood test measures levels of thyroid hormone and thyroid-stimulating hormone in your blood. The pituitary gland releases TSH to stimulate the thyroid to produce its hormones. High thyroxine and low TSH levels indicate that your thyroid gland is overactive.
Your doctor might also give you radioactive iodine by mouth or as an injection, and then measure how much of it your thyroid gland takes up. Your thyroid takes in iodine to produce its hormones. Taking in a lot of radioactive iodine is a sign that your thyroid is overactive. The low level of radioactivity resolves quickly and isnt dangerous for most people.
Treatments for hyperthyroidism destroy the thyroid gland or block it from producing its hormones.
- Antithyroid drugs such as methimazole prevent the thyroid from producing its hormones.
- A large dose of radioactive iodine damages the thyroid gland. You take it as a pill by mouth. As your thyroid gland takes in iodine, it also pulls in the radioactive iodine, which damages the gland.
- Surgery can be performed to remove your thyroid gland.
If you have radioactive iodine treatment or surgery that destroys your thyroid gland, you will develop hypothyroidism and need to take thyroid hormone daily.

Hypothyroidism Vs Hyperthyroidism: How Do They Differ
Thyroid disease affects approximately 20 million people in the U.S. However, experts think that the majority of people with thyroid disease dont know they have it.

When Is Consultation With An Endocrinologist Indicated For Patients With Hypothyroidism
Indications for referral to an endocrinologist include any of the following :
A nodular thyroid, suspicious thyroid nodules, or compressive symptoms
Underlying cardiac disorders or other endocrine disorders
Age younger than 18 years
Secondary or tertiary hypothyroidism
Unusual constellation of thyroid function test results
Inability to maintain TSH in the target range
Unresponsiveness to treatment
Some patients with subacute or postpartum thyroiditis can develop thyrotoxicosis before developing hypothyroidism. These patients also may benefit from consultation with an endocrinologist.
Suspected myxedema coma is a medical emergency with a high risk of mortality, and it necessitates requires initiation of IV LT4 and glucocorticoid therapy before laboratory confirmation. An urgent endocrinology consultation should be obtained.
Rarely, an increase in size of a goiter in a patient with autoimmune thyroid disease could indicate a lymphoma. These patients should be evaluated by an endocrinologist.

Clinical Relevance: Thyroglossal Cyst
In the embryo, the thyroid gland begins development near the base of the tongue in an area known as the foramen cecum. It descends during development and reaches its destination in the anterior neck by week 7.
The descent of the developing thyroid gland forms the thyroglossal duct an epithelialised tract that connects the gland to its origin at the foramen cecum. It usually regresses by the 10th week of gestation, but can persist in some individuals. If it fails to regress, the duct can give rise to cysts or fistulae.
A thyroglossal cyst results from a build-up of secretions within the duct. It typically presents as a midline lump in the anterior neck which rises on tongue protrusion. If left untreated, this cyst can become infected, and form a cutaneous fistula discharging out onto the skin of the anterior neck.
Thyroglossal cysts and fistulae are usually treated with complete excision. Recurrence is quoted at approximately 2.5%.

If Part Of My Thyroid Is Surgically Removed Will The Other Part Be Able To Make Enough Thyroid Hormones To Keep Me Off Of Medication
Sometimes, your surgeon may be able to remove part of your thyroid and leave the other part so that it can continue to create and release thyroid hormones. This is most likely in situations where you have a nodule thats causing your thyroid problem. About 75% of people who have only one side of the thyroid removed are able to make enough thyroid hormone after surgery without hormone replacement therapy.
Who Treats Thyroid Disease
Several types of doctors can play a role in managing thyroid disease and its symptoms. Some people only see one doctor for thyroid-related issues, while others have a medical team they work with to manage their disease. The types of doctors you may want to consider include:
- Primary care doctors
- Holistic thyroid practitioners, including naturopaths and chiropractors

What Are The Symptoms Of A Thyroid Nodule
Most thyroid nodules do not cause symptoms. Often, thyroid nodules are discovered incidentally during a routine physical examination or on imaging tests like CT scans or neck ultrasound done for completely unrelated reasons. Occasionally, patients themselves find thyroid nodules by noticing a lump in their neck while looking in a mirror, buttoning their collar, or fastening a necklace. Abnormal thyroid function tests may occasionally be the reason a thyroid nodule is found. Thyroid nodules may produce excess amounts of thyroid hormone causing hyperthyroidism . However, most thyroid nodules, including those that cancerous, are actually non-functioning, meaning tests like TSH are normal. Rarely, patients with thyroid nodules may complain of pain in the neck, jaw, or ear. If a nodule is large enough to compress the windpipe or esophagus, it may cause difficulty with breathing, swallowing, or cause a tickle in the throat. Even less commonly, hoarseness can be caused if the nodule invades the nerve that controls the vocal cords but this is usually related to thyroid cancer.
The important points to remember are the following:
- Thyroid nodules generally do not cause symptoms.
- Thyroid tests are most typically normaleven when cancer is present in a nodule.
- The best way to find a thyroid nodule is to make sure your doctor checks your neck!
This Woman’s Viral Photo Shows What A Thyroid Cancer Lump Looks Like
A before-and-after photo reveals a lump she never realized she had.
The thyroid is a complex part of the body, so it’s no wonder diagnosing thyroid-related diseases like Hashimoto’s disease, Graves’ disease, or thyroid cancer can be extremely difficult. Now, one woman is raising awareness of thyroid cancer symptoms on Twitter. Last Wednesday, Lorna Brown tweeted a photo of her neck before and after a thyroid operation.
In her post titled “Thyroid Cancer – What to Look for From Someone Who Knows,” Brown explains the photo on the left was taken by her brother almost a year before her thyroid cancer diagnosis. “You can clearly see the lump on my neck, here in this picture. Yet we missed it at the time!” she writes. Brown goes on to explain that the lump on her neck is a telltale sign of thyroid cancersomething she never knew before her diagnosis. “Please check your neck, and look at others around you,” she urges readers. “Most thryroid cysts are benign, but some aren’t. Mine certainly wasn’t.”
Brown’s suggestion is a smart one. More than 30 million Americans have a thyroid disorder and more than 60,000 Americans are affected by thyroid cancer annually. The most common symptom of thyroid cancer is a hard lump on the neckbut most patients experience no symptoms at all. Two in three cases of thyroid cancer occur in people under age 55, and 75% of thyroid cancer cases occur women.
