Hyperthyroidism is a condition of overactive thyroid function, leading to excessive production of thyroid hormones triiodothyronine (T3) and/or thyroxine (T4). As thyroid hormones control several body functions, including metabolism, this excess causes extra stimulation which speeds up some body systems. Thyrotoxicosis is used to describe hyperthyroidism which is presenting symptoms (is symptomatic).
Several classifications of hyperthyroidism include:
De Quervain
Graves' disease (in Europe, Basedow's disease)
Hashitoxicosis
Iatrogenic hyperthyroidism
Thyroid storm
Toxic nodular struma
Toxic nodule
Symptoms related to hyperthyroidism may include:
Anxiety
Cardiac arrhythmias and palpitations
Chorea (involuntary muscle movements, a dyskinesia)
Decreased libido
Depression and apathy
Diarrhea
Dyspnea (shortness of breath)
