What is Thyroiditis?
Thyroiditis is inflammation of the thyroid gland. This condition can cause the thyroid to become swollen and painful, and it may affect how well the gland produces thyroid hormones. Thyroiditis can be temporary or chronic and can lead to either overactive (hyperthyroidism) or underactive (hypothyroidism) thyroid function.
What Are the Symptoms of Thyroiditis?
Symptoms vary depending on the type and stage of thyroiditis but commonly include:
Common Symptoms:
- Pain or tenderness in the neck or thyroid area
- Swelling or enlargement of the thyroid gland
- Fatigue and weakness
- Fever (especially in infectious thyroiditis)
- Changes in thyroid hormone levels causing symptoms such as:
- Hyperthyroidism: nervousness, weight loss, rapid heartbeat
- Hypothyroidism: fatigue, weight gain, cold intolerance
- Difficulty swallowing or a feeling of tightness in the throat
What Causes Thyroiditis?
Thyroiditis has several causes, including:
Common Causes and Risk Factors:
- Autoimmune diseases (e.g., Hashimoto’s thyroiditis) where the immune system attacks the thyroid
- Viral infections leading to subacute thyroiditis
- Bacterial infections causing acute infectious thyroiditis (rare)
- Radiation therapy to the neck
- Certain medications that affect thyroid function
- Postpartum thyroiditis occurring after childbirth
- Trauma or injury to the thyroid gland
How is Thyroiditis Diagnosed?
Doctors diagnose thyroiditis based on symptoms, physical exam, and tests:
Common Diagnostic Tests:
- Blood tests to measure thyroid hormone levels and antibodies
- Ultrasound to assess the size and inflammation of the thyroid
- Thyroid scan to evaluate function and detect inflammation
- Fine needle aspiration biopsy in some cases to rule out infection or cancer
How is Thyroiditis Treated?
Treatment depends on the cause and symptoms:
Treatment Options:
- Anti-inflammatory medications such as NSAIDs or corticosteroids for pain and swelling
- Beta blockers to control symptoms of hyperthyroidism (e.g., rapid heartbeat)
- Thyroid hormone replacement if hypothyroidism develops
- Antibiotics for bacterial thyroiditis
- Regular monitoring of thyroid function until recovery
Complications of Thyroiditis
Possible complications include:
- Chronic hypothyroidism if the thyroid is permanently damaged
- Thyroid hormone imbalances causing persistent symptoms
- Recurrence of inflammation in some autoimmune forms
- Rarely, thyroid abscess formation in infectious cases
Living with Thyroiditis
Most cases of thyroiditis improve with treatment and monitoring. Managing symptoms and regular check-ups are important.
Tips for Living Well:
- Follow your doctor’s advice on medications and monitoring
- Report new or worsening symptoms promptly
- Maintain a healthy diet and manage stress
- Avoid iodine supplements unless advised by a healthcare provider
- Keep track of thyroid function tests as recommended
