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.
