What Symptoms Can Thyroid Nodules Cause

What Is The Thyroid Gland

Thyroid Nodules: Causes, Symptoms & Treatments | Dr. Kannan

The thyroid gland is a butterfly-shaped endocrine gland that is normally located in the lower front of the neck. The thyroids job is to make thyroid hormones, which are secreted into the blood and then carried to every tissue in the body. Thyroid hormone helps the body use energy, stay warm and keep the brain, heart, muscles, and other organs working as they should.

What Causes A Thyroid Nodule To Form

Sometimes the thyroid begins to grow , causing one or more nodules to form. Why this happens is not known. Cancer is the biggest concern when nodules form. Fortunately, cancer is very rare it is found in less than 5 percent of all nodules. Nodules develop more often in people who have a family history of nodules, and in people who dont get enough iodine. Iodine is needed to make thyroid hormone.

There are different types of thyroid nodules:

  • Colloid nodules: These are one or more overgrowths of normal thyroid tissue. These growths are benign . They may grow large, but they do not spread beyond the thyroid gland.
  • Thyroid cysts: These are growths that are filled with fluid or partly solid and partly filled with fluid.
  • Inflammatory nodules: These nodules develop as a result of chronic inflammation of the thyroid gland. These growths may or may not cause pain.
  • Multinodular goiter: Sometimes an enlarged thyroid is made up of many nodules .
  • Hyperfunctioning thyroid nodules: These nodules autonomously produce thyroid hormone without regard for normal feedback control mechanisms, which may lead to the development of hyperthyroidism. Hyperthyroidism can affect the heart and cause such problems as sudden cardiac arrest, high blood pressure, arrhythmias , osteoporosis and other health problems.
  • Thyroid cancer: Less than 5 percent of thyroid nodules are cancerous.

Improving Gut Health May Improve Thyroid Conditions

Theres some encouraging preliminary evidence to suggest that improving your gut can help you improve your thyroid health. Improving the balance of your gut microbiome has been shown in some studies to promote optimal thyroid hormone levels and improve thyroid symptoms. For example:

  • In a clinical trial, 8 weeks of probiotic supplementation improved thyroid hormone levels;and symptoms compared to a placebo. [8

Lab Testing & Ultrasound Testing

If you have a known thyroid nodule, or if you suspect a thyroid nodule, then the next step is to undergo testing.;

Testing, in this case, takes the form of 2 different modalities:

The first is lab testing which helps to assess how well your thyroid is working.;

And the second is to directly assess the thyroid itself through ultrasound imaging.;

Thyroid lab tests give you an idea of how responsive your thyroid gland is and if your thyroid nodule is causing any impairment in the ability of your gland to produce thyroid hormone.;

Thyroid ultrasound, on the other hand, will directly image the thyroid gland and give you key information about the size and other characteristics of your nodule and thyroid tissue .;

These characteristics are important because they can help your doctor determine if your nodule look suspicious or if you are at increased risk for thyroid cancer.;

If your nodule looks suspicious on thyroid ultrasound then your Doctor will likely order a fine needle aspiration .

FNA is the best way to determine if your nodule is cancerous and if it needs to be removed, but not everyone should get an FNA unless absolutely necessary.;

The reason is that up to 25% of all FNA biopsy results come back as “indeterminate” which means it could be cancer or it could be benign, it’s medical terminology for “I’m not sure”.;

Having an indeterminate result on your biopsy can be stressful and may require further imaging studies and biopsies over time.;

Thyroid Nodules: Symptoms, Causes, and Support Strategies
  • 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!

What Causes Thyroid Nodules

Doctors arent always sure why some people get thyroid nodules, but theyre very common. The chances of getting one increase as you get older. Almost 50% of adults will develop thyroid nodules by the time theyre 60 years old.

The nodules are sometimes associated with other medical conditions, including:

Are There Any Side

A minority of patients experience a sore feeling or discomfort in the front of the neck following radioiodine treatment. The radioiodine can also cause the thyroid gland to become underactive in a minority of cases.;The patient would then need to take tablets for life to replace the thyroid hormone. ;

It is also important for patients having radioiodine treatment to stay away from children and pregnant women for three weeks to avoid exposing them to radiation.;Patients should speak to their doctor about pregnancy as it should be avoided for up to six months after treatment. Patients should discuss any concerns with their doctor.;More information on the practicalities of radioiodine treatment can be obtained from the hospitals Medical Physics department where the treatment will take place.

If the whole thyroid gland is removed, thyroid hormone replacement tablets will need to be taken for life.

Taking carbimazole tablets can cause side-effects such as reducing the number of white blood cells in the body; however, this is very rare.;Patients who develop a sore throat or raised temperature whilst taking carbimazole should see their doctor as soon as possible.

How Is Postpartum Thyroiditis Treated

Treatment for postpartum thyroiditis depends on the phase of the disease and what symptoms you have. For example, if you get symptoms of hyperthyroidism in the first phase, your treatment may include medicines to slow down the heart rate.

In most women who have postpartum thyroiditis, the thyroid returns to normal within 12 to 18 months after symptoms start. But if you have a history of postpartum thyroiditis, your risk is higher for developing permanent hypothyroidism within 5 to 10 years.

What Increases Your Risk For Thyroid Nodules

Thyroid Nodules Most Common Cause

You are more likely to develop a thyroid nodule if:

  • You are older.
  • Thyroid nodules are more common in older people.
  • You are female.
  • Women are more likely than men to develop thyroid nodules.
  • You have been exposed to radiation.
  • Exposure to environmental radiation or past radiation treatment to your head, neck, and chest increases your risk for thyroid nodules.
  • You do not get enough iodine.
  • Iodine deficiency is rare in the United States, but it is common in areas where iodine is not added to salt, food, and water. An iodine deficiency may result in an enlarged thyroid gland , with or without nodules.
  • You have Hashimoto’s thyroiditis.
  • Hashimoto’s thyroiditis can cause an underactive thyroid gland .
  • One or both of your parents have had thyroid nodules.

    What Are Goiters And Thyroid Nodules

    An enlarged thyroid gland can be felt as a lump under the skin at the front of the neck. When it is large enough to see easily, it’s called a goiter.

    A thyroid nodule is a lump or enlarged area in the thyroid gland. A nodule may simply be swollen tissue, an overgrowth of normal thyroid tissue, or a collection of fluid called a cyst. Most thyroid nodules in children are not caused by cancer.

    What Is A Toxic Thyroid Nodule

    Ultrasound scan in transverse section of the thyroid gland of a 73-year-old female patient, showing a hot nodule in one thyroid lobe corresponding to a toxic adenoma.

    A toxic thyroid nodule causes hyperthyroidism .;This occurs when a single nodule grows on the thyroid gland causing it to become enlarged and produce excess thyroid hormones. If the increased hormone production is coming from a single nodule in the gland, this is called toxic adenoma. If there are many nodules causing the hyperthyroidism, this is referred to as multinodular goitre.

    How Does Thyroid Disease Affect Pregnancy

    Pregnancy-related hormones raise the level of thyroid hormones in the blood. Thyroid hormones are necessary for the baby’s brain development while in the womb.

    It can be harder to diagnose thyroid problems during pregnancy because of the change in hormone levels that normally happen during pregnancy. But it is especially important to check for problems before getting pregnant and during pregnancy. Uncontrolled hyperthyroidism and hypothyroidism can cause problems for both mother and baby.

    Hyperthyroidism that is not treated with medicine during pregnancy can cause:

    • Premature birth
    • a serious condition starting after 20 weeks of pregnancy. Preeclampsia causes high blood pressure and problems with the kidneys and other organs. The only cure for preeclampsia is childbirth.
    • Thyroid storm
    • Fast heart rate in the newborn, which can lead to heart failure, poor weight gain, or an enlarged thyroid that can make it hard to breathe
    • Low birth weight
    • Miscarriage

    Thyroid Nodule: When Is A Radioiodine Scan Ordered

    Thyroid Nodule: Causes, Signs, Symptoms, Diagnosis & Treatment

    Only in instances where the blood test to examine the thyroid nodule patient demonstrates that hyperthyroidism is present in addition to the presence of the thyroid nodule, is a radioiodine scan indicated. In these cases, the thyroid stimulating hormone will be very low. The thyroid nodule patient may or may not have recognized symptoms of hyperthyroidism. If the TSH level is normal, there is absolutely no contemporary indication for a thyroid scan.

    During the thyroid scan, the patient will be given a small amount of radioactive iodine in their vein and a special imaging camera is utilized to determine how much iodine is taken up by the thyroid gland and if the nodule takes up iodine relative to the remainder of the thyroid gland . If the nodule has less iodine uptake than the rest of the thyroid gland, then the thyroid nodule is called a √Ęcold nodule√Ę.

    Hot nodules are almost always non-cancerous but the preferred management of hot nodules is frequently surgery since it is a clear, safe and 100% effective therapy for the hyperthyroidism. Cold nodules have a higher incidence of malignancy than hot nodules but still most are benign. is an educational service of the Clayman Thyroid Center, the world’s leading thyroid cancer surgery center.

    How Are They Diagnosed

    If your doctor thinks you have a nodule, he or she will do a physical exam and will ask you if you have symptoms or about any changes in how you’ve been feeling.

    You may have tests to see how well your thyroid is working. Possible tests include:

    • A blood test to check the level of thyroid hormone in your body.
    • A thyroid scan to get information about your thyroid gland and nodules. Another test called an uptake scan can be done at the same time to see how well your thyroid gland is working.
    • A thyroid ultrasound to see the number and size of nodules.

    You may have a fine-needle aspiration to remove a small amount of material from the nodule to check for cancer.

    If your nodule is not cancerous, your doctor will see you regularly to monitor the size of your nodule.

    How Are Thyroid Nodules Diagnosed

    Thyroid Nodules: Symptoms, Causes, Diagnosis, Treatment ...
    Fine Needle Biopsy

    A;thyroid fine needle biopsy;is a simple procedure that can be performed in the physician’s office. Some physicians numb the skin over the nodule prior to the biopsy, but it is not necessary to be put to sleep, and patients can usually return to work or home afterward with no ill effects.

    This test provides information that no other test can offer short of surgery.;A thyroid needle biopsy will provide sufficient information on which to base a treatment decision more than 85 percent of the time if an ultrasound is used.

    Use of fine needle biopsy has drastically reduced the number of patients who have undergone unnecessary operations for benign nodules. However, about 10-20 percent of biopsy specimens are interpreted as inconclusive or inadequate, that is, the pathologist cannot be certain whether the nodule is cancerous or benign.

    In such cases, a physician who is experienced with thyroid disease can use other criteria to make a decision about whether to operate.

    Thyroid Scan

    A;thyroid scan;is a picture of the thyroid gland taken after a small dose of a radioactive isotope normally concentrated by thyroid cells has been injected or swallowed. The scan tells whether the nodule is hyperfunctioning . Because cancer is rarely found in hot nodules, a scan showing a hot nodule eliminates the need for fine needle biopsy. If a hot nodule causes hyperthyroidism, it can be treated with radioiodine or surgery.
