Overview

De Quervain's thyroiditis can be classified according to the development of symptoms into the prodromal stage, hyperthyroid stage, euthyroid stage, and hypothyroid stage.

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 and tremors.
• Irritability and nervousness.

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.
