Transient autoimmune thyroiditis occurring in the POSTPARTUM PERIOD. It is characterized by the presence of high titers of AUTOANTIBODIES against THYROID PEROXIDASE and THYROGLOBULIN. Clinical signs include the triphasic thyroid hormone pattern: beginning with THYROTOXICOSIS, followed with HYPOTHYROIDISM, then return to euthyroid state by 1 year postpartum.

Inflammatory diseases of the THYROID GLAND. Thyroiditis can be classified into acute (THYROIDITIS, SUPPURATIVE), subacute (granulomatous and lymphocytic), chronic fibrous (Riedel's), chronic lymphocytic (HASHIMOTO DISEASE), transient (POSTPARTUM THYROIDITIS), and other AUTOIMMUNE THYROIDITIS subtypes.

Disorders or diseases associated with PUERPERIUM, the six-to-eight-week period immediately after PARTURITION in humans.

A hemeprotein that catalyzes the oxidation of the iodide radical to iodine with the subsequent iodination of many organic compounds, particularly proteins. EC 1.11.1.8.

Inflammatory disease of the THYROID GLAND due to autoimmune responses leading to lymphocytic infiltration of the gland. It is characterized by the presence of circulating thyroid antigen-specific T-CELLS and thyroid AUTOANTIBODIES. The clinical signs can range from HYPOTHYROIDISM to THYROTOXICOSIS depending on the type of autoimmune thyroiditis.

Spontaneously remitting inflammatory condition of the THYROID GLAND, characterized by FEVER; MUSCLE WEAKNESS; SORE THROAT; severe thyroid PAIN; and an enlarged damaged gland containing GIANT CELLS. The disease frequently follows a viral infection.

Chronic autoimmune thyroiditis, characterized by the presence of high serum thyroid AUTOANTIBODIES; GOITER; and HYPOTHYROIDISM.

Acute inflammatory disease of the THYROID GLAND due to infections by BACTERIA; FUNGI; or other microorganisms. Symptoms include tender swelling, FEVER, and often with LEUKOCYTOSIS.

Thyroglobulin is a glycoprotein synthesized and secreted by thyroid follicular cells, serving as a precursor for the production of thyroid hormones T3 and T4, and its measurement in blood serves as a tumor marker for thyroid cancer surveillance.

A highly vascularized endocrine gland consisting of two lobes joined by a thin band of tissue with one lobe on each side of the TRACHEA. It secretes THYROID HORMONES from the follicular cells and CALCITONIN from the parafollicular cells thereby regulating METABOLISM and CALCIUM level in blood, respectively.

A common form of hyperthyroidism with a diffuse hyperplastic GOITER. It is an autoimmune disorder that produces antibodies against the THYROID STIMULATING HORMONE RECEPTOR. These autoantibodies activate the TSH receptor, thereby stimulating the THYROID GLAND and hypersecretion of THYROID HORMONES. These autoantibodies can also affect the eyes (GRAVES OPHTHALMOPATHY) and the skin (Graves dermopathy).
