Is your thyroid gland swollen in your neck? Let's talk about thyroiditis!

Have you ever felt a small lump in the front of your neck, a tingling sensation in your hand, or just plain tired and anxious? One of the reasons for this is a condition called thyroiditis . The name may sound like a big deal, but let's talk about it simply and in a way that you can understand.

What is Thyroiditis? Let's understand it simply!

Simply put, thyroiditis is an inflammation of your thyroid gland , which means swelling. Now you may be wondering what the thyroid gland is and where it is located. Think of it this way, the thyroid gland is a small butterfly-shaped organ in the front of your neck, just under the skin. It is part of our body's endocrine system . It produces and secretes several types of hormones that control many important functions in our body. Now, this condition called thyroiditis is not a single type of thing. It is actually a general name for a group of conditions that cause inflammation of the thyroid gland, with different causes and symptoms. The main thing that can cause this thyroiditis is that thyroid hormones are either produced too much or too little.

What are the stages of thyroiditis?

Most often, there are three main phases in most types of thyroiditis. Let's take a look at what they are: 1. Thyrotoxic phase: In this phase, your thyroid gland swells and suddenly releases too much hormone. This causes a temporary condition called thyrotoxicosis . It's like a sudden flood of hormones. 2. Hypothyroid phase: Now after that sudden surge of hormones, after a few weeks or months, the thyroid gland doesn't have enough hormones left to release. Then, a deficiency of thyroid hormone occurs. This is called hypothyroidism . In some types of thyroiditis, such as Hashimoto's thyroiditis and radiation-induced thyroiditis, this hypothyroid phase is permanent. 3. Euthyroid phase: During this phase, your thyroid hormone levels return to normal. This may occur temporarily after the thyrotoxic phase, before entering the hypothyroid phase. Or, it may be the final phase, when the thyroid gland has recovered from the inflammation and is producing hormones normally again.

What are the main types of thyroiditis?

As we've discussed before, thyroiditis is not just one disease. There are different types of it. Let's take a look at what they are:

• Hashimoto's thyroiditis: This is the most common type of thyroiditis.. This is also called chronic lymphocytic thyroiditis . This is an autoimmune condition. That is, our own body's immune system attacks the thyroid gland by producing antithyroid antibodies . This is the main cause of hypothyroidism .
• Silent or painless thyroiditis: This is also an autoimmune condition. It is also caused by anti-thyroid antibodies. As the name suggests, it is not very painful.
• Postpartum thyroiditis: This is also an autoimmune condition. However, it occurs within a year after giving birth. This is relatively rare.
• Radiation-induced thyroiditis: This condition can be caused by radiation therapy for some types of cancer or by radioactive iodine given to treat hyperthyroidism .
• Subacute thyroiditis or de Quervain's thyroiditis: This is a painful condition that is often caused by a virus. It often occurs after an upper respiratory infection , such as a cold or flu, has passed.
• Acute infectious thyroiditis: This is a very rare condition. It is caused by an infectious organism, such as a bacterium .
• Drug-induced thyroiditis: This condition can occur when certain medications, such as amiodarone , interferons , lithium, and cytokines, are used. However, not everyone who takes these medications develops this condition, only a small number of people.
• Riedel thyroiditis: This is also a very rare disease. It is characterized by long-term inflammation and fibrosis of the thyroid gland.The condition is called fibrosis. Fibrosis is a thickening or scarring of tissue.

Who is most affected by thyroiditis?

Although thyroiditis can affect anyone, it affects women more often. For example, a type of thyroiditis called Hashimoto's thyroiditis is four to ten times more common in women than in men. It is also most common in people between the ages of 30 and 50. Silent or painless thyroiditis is also more common in women. It is the second most common type of thyroiditis after Hashimoto's thyroiditis.

How common is this condition?

As we mentioned earlier, the most common type is Hashimoto's thyroiditis. It is estimated to affect between 1% and 2% of the population in the United States. Other types of thyroiditis are much rarer.

Is Thyroiditis life-threatening?

Thyroiditis is usually not life-threatening.

However, if you develop hyperthyroidism due to thyroiditis and it is left untreated for a long time, there is a risk of developing a dangerous, life-threatening condition called thyroid storm .

What are the symptoms of a thyroid storm?

• High fever – A fever can range from 104 to 106 degrees Fahrenheit (40-41 degrees Celsius).
• Rapid heartbeat (tachycardia) – can exceed 140 beats per minute.
• Feeling constantly anxious, irritable, and/or restless.
• Delirium – This is a condition of impaired consciousness and confusion.

If you have any of these symptoms, go to the nearest hospital immediately. This is an emergency! If you think you have symptoms of thyroiditis, it is very important to see a doctor right away. They can then run the necessary tests, diagnose the condition, and start treatment.

What are the symptoms of Thyroiditis?

Symptoms of thyroiditis depend on the type and stage of the disease. In most types of thyroiditis, symptoms of thyrotoxicosis appear first, followed by symptoms of hypothyroidism. In subacute thyroiditis and acute infectious thyroiditis, there is usually pain in the area where the thyroid gland is located. Some people may develop an enlarged thyroid gland, called a goiter .

Symptoms of Thyrotoxicosis (when hormones increase)

The thyrotoxic phase of thyroiditis is usually short-lived, lasting about one to three months. If your thyroid cells are quickly damaged and too much thyroid hormone is released, you may experience symptoms of hyperthyroidism ( overactive thyroid gland). These include:

• Heart palpitations.
• Increased appetite.
• Being thin for no reason.
• Constantly feeling anxious and restless.
• Quick to anger.
• Insomnia.
• Increased sweating and sensitivity to heat.
• Tremors.

Symptoms of Hypothyroidism (low hormones)

The hypothyroid phase of thyroiditis can last a long time, and may even be permanent. If your thyroid cells are damaged and your thyroid hormone levels drop, you may experience symptoms of hypothyroidism. These include:

• Feeling tired all the time.
• Getting bigger for no reason.
• Constipation.
• Mental conditions like depression.
• Dry skin.
• Increased sensitivity to cold.
• Muscle weakness.
• Decreased ability to concentrate.

What are the causes of Thyroiditis?

Thyroiditis occurs when your thyroid gland is "attacked" by something, causing it to swell (this is the body's response to injury) and damaging the thyroid cells. The causes vary depending on the type. The most common cause is an autoimmune disease . This means that the immune system, which is supposed to protect our bodies, mistakenly attacks our own bodies. It's not yet known exactly why this happens. Most types of thyroiditis are caused by antibodies that attack your thyroid gland.

How is thyroiditis diagnosed?

When you see a doctor, they will examine you and examine your thyroid gland. They will then ask about your symptoms and any previous illnesses you have. If they suspect that you have thyroiditis, they may do some or all of these tests to confirm the diagnosis:

• Thyroid function tests: These are blood tests that check your thyroid-related hormones and thyroid hormone levels. For example, your thyroid-stimulating hormone (TSH) , triiodothyronine (T3) , and thyroxine (T4) . TSH comes from your pituitary gland . It stimulates your thyroid gland to produce the hormones T4 and T3. Together, these two are called thyroid hormones.
• Thyroid ultrasound:Doctors often use an ultrasound to look at the structure of the thyroid gland. This can detect things like a thyroid nodule , changes in blood flow, and the density of the gland.
• Thyroid antibody tests: These are also blood tests. They look for thyroid antibodies, either antithyroid (microsomal) antibodies (TPO) or thyroid receptor stimulating antibodies (TRAb) . If these antibodies are present, it means you may have a type of thyroiditis caused by an autoimmune disease.
• Erythrocyte sedimentation rate (ESR or sed rate): This is also a blood test. It helps to find out if there is inflammation in your body. ESR is elevated in subacute thyroiditis.
• C-reactive protein (CRP): This measures the level of CRP in your blood. CRP levels increase when there is inflammation in the body. It can be very high in acute infectious thyroiditis.
• Radioactive iodine uptake (RAIU) test: This test measures how much radioactive iodine (given by mouth) your thyroid gland absorbs. This amount is always low in the thyrotoxic phase of thyroiditis.

How is thyroiditis treated?

Treatment for thyroiditis depends on the type and symptoms.

Treatment of Thyrotoxicosis

If you are in the thyrotoxic phase of thyroiditis, your doctor may give you a type of medication called beta-blockers . These can help reduce your heart rate ( palpitations ) and tremors. As your symptoms improve, your doctor will gradually reduce and stop the medication. This is because the thyrotoxic phase is temporary.

Treatment for Hypothyroidism

If you have Hashimoto's thyroiditis, your doctor will give you thyroid hormone replacement medication, such as levothyroxine . You will need to take this medication for the rest of your life. Hypothyroidism caused by Hashimoto's thyroiditis is usually permanent. If you have subacute, silent, or postpartum thyroiditis, and you have symptoms of hypothyroidism, your doctor will also give you thyroid hormone replacement medication. You will need to take this medication for about 6 to 12 months. Then your doctor will gradually reduce the dose to see if you have permanent hypothyroidism. If your hypothyroidism is not severe, meaning you have few symptoms, you may not need medication at all.

Other treatments for thyroiditis

If you have acute infectious thyroiditis , you will need to treat the infection. This will most likely involve antibiotics . If you have an abscess , or an opening, in your thyroid, your doctor may need to do a fine-needle aspiration (sucking out pus with a syringe) to drain the pus. Drug-induced thyroiditis usually only lasts as long as you take the medication that caused it. Your doctor may be able to switch you to a different medication that is similar to the one you are taking. Or, you may be given levothyroxine for the thyroiditis while you continue taking the medication. Pain from acute infectious thyroiditis and subacute thyroiditis can usually be controlled with nonsteroidal anti-inflammatory drugs (NSAIDs) , such as aspirin or ibuprofen . Sometimes, steroid therapy may be used if the pain is severe. Riedel thyroiditis may require surgery.

Can thyroiditis be prevented?

Unfortunately, many types of thyroiditis cannot be prevented. If you have a condition that requires radioactive iodine or radiation therapy, talk to your doctor about your risk of developing thyroiditis. You may be able to start other treatments to prevent thyroiditis from developing. If you are taking medications that can cause thyroiditis, talk to your doctor about the risk and whether you can stop taking those medications. However, even doing so may not prevent thyroiditis.

What is the prognosis of thyroiditis?

The outlook for thyroiditis is generally good . In Hashimoto's thyroiditis, the resulting hypothyroidism is usually permanent. However, it can be managed with lifelong thyroid hormone replacement therapy. People with subacute thyroiditis usually have symptoms for about one to three months. However, it can take 12 to 18 months for thyroid function to fully return to normal. These people have a 5% risk of developing permanent hypothyroidism. Postpartum and silent (painless) thyroiditis also take 12 to 18 months to fully recover. People with these conditions have a 20% risk of developing permanent hypothyroidism.

When should you see a doctor about thyroiditis?

If you have been diagnosed with thyroiditis, you should see a doctor regularly to check your symptoms and make sure your treatment is working properly. Your symptomsIf it gets worse, or if you develop more worrisome symptoms , talk to your doctor as soon as possible.

It's normal to feel stressed when you find out you have a condition. But the good news is that thyroiditis is a treatable condition, and it can often be temporary. If you have any questions about your thyroiditis or your treatment plan, talk to your doctor. They are here to help.
