Thyroid Problems

Equip yourself. Learn about thyroid problems.


Hyperthyroidism is a condition of overactive thyroid function, leading to excessive production of thyroid hormones: either triiodothyronine (T3), thyroxine (T4), or both. As thyroid hormones control several body functions, including metabolism, this excess causes extra stimulation which increases the pace of some body systems. Another word, thyrotoxicosis, is used to describe hyperthyroidism which is presenting symptoms in the patient.

Several classifications of hyperthyroidism include:

De Quervain

Graves' disease (in Europe, Basedow's disease)


Iatrogenic hyperthyroidism

Thyroid storm

Toxic nodular struma

Toxic nodule


A wide selection of symptoms can potentially appear in a patient who has hyperthyroidism. However, do not attempt to diagnose the situation yourself based on medical symptoms that are present -- rather, talk with a doctor for more details on diagnosis, as well as treatment. Moreover, please keep in mind that this list of hyperthyroidism symptoms is not comprehensive. Additionally, in some cases, hyperthyroidism does not cause any noticeable symptoms. However, some that are possible are presented below:

Cardiac arrhythmias and palpitations
Chorea (involuntary muscle movements, a dyskinesia)
Decreased libido
Depression and apathy
Dyspnea (shortness of breath)
Hair loss
Heat intolerance
High blood pressure
Low blood cholesterol levels
Muscle pain (myalgia)
Periodic paralysis
Perspiration (sweating)
Polydipsia (increased fluid intake)
Polyuria (increased urine output)
Raised heart rate
Hand tremors
Weight loss (despite increased appetite)

Diagnosis and treatment

If hyperthyroidism is suspected, a doctor or medical professional may use certain tests to try to make a diagnosis for the patient. Once a hyperthyroidism diagnosis is established, proper treatment may begin. The treatment that is given varies in different circumstances, and one of the things that is taken into consideration is the type of hyperthyroidism which is impacting the individual. Different medications may be used, and surgery and radioiodine therapy are also some methods that are employed.
