Causes

Hashimoto's disease

Hashimoto's disease (chronic lymphocytic thyroiditis) causes thyroid gland inflammation and often an underactive thyroid (hypothyroidism). Treatment may involve thyroid hormone replacement medication.

Hyperthyroidism

Hyperthyroidism occurs when your thyroid gland produces too much of the hormone thyroxine — speeding up your metabolism and sometimes leading to serious complications.

Tests and diagnosis

Ultrasound

Ultrasound imaging uses high-frequency sound waves to create images of structures in your body.

Treatments and drugs

Thyroidectomy

Thyroidectomy is surgery to remove all or part of your thyroid gland. Thyroidectomy may be used to treat thyroid disorders, including cancer, goiter and hyperthyroidism.
