Hyperthyroidism

Over Active Thyroid

What is hyperthyroidism?           

An overactive thyroid, or hyperthyroidism, causes thyroid hormone levels to be higher than normal.  This leads to an unhealthy stimulation of the body’s metabolic rate.  The main cause of hyperthyroidism is Graves’ disease and common symptoms include nervousness, hyperactivity, irritability, and even hypertension.  If left untreated, it can lead to serious conditions which can eventually be fatal.  Graves’ disease is caused by the body’s immune system over-stimulating the thyroid gland and causing it to overproduce T3 and T4.

How is hyperthyroidism diagnosed and treated?

Diagnosis of hyperthyroidism begins with a full examination and can be easily spotted if the thyroid is enlarged. Following this, a blood sample is analyzed to determine the T3 and T4 levels. If the test confirms hyperthyroidism, there are multiple treatments available. Anti-thyroid drugs are available which reduce thyroid activity. If diagnosed early, anti-thyroid drugs can sometimes effectively cure hyperthyroidism. Another treatment method involves the ingestion of radioactive iodine. Administration causes a reduction in thyroid activity. If need be, a partial thyroid removal procedure, or thyroidectomy, can be performed and with general follow-up treatment, the condition can be cured.  The following page provides more details on hyperthyroidism treatment.
