Classification

De Quervain's thyroiditis can be classified according to the development of symptoms into the following stages:

1.Prodromal stage

It includes:

• Low-grade fever and viral flu-like symptoms, such as sore throat, myalgia, arthralgia, and malaise.
• High-grade fever and neck pain with a tender and diffuse thyroid gland enlargement follow flu-like symptoms.

1.Hyperthyroid stage

It follows the prodromal stage and includes the symptoms of thyrotoxicosis such as:

• Tachycardia
• Tremors
• Irritability
• Nervousness
• Weight loss

2.Euthyroid stage

Thyrotoxic stage is followed by a 1–3-week period of euthyroid phase.

4.Hypothyroid stage

The transient hypothyroid stage lasts for 6-12 months.

• Rarely, the hypothyroid stage may persist for a longer duration.
