Hyperthyroidism is a condition where they thyroid is overactive.  In this condition the thyroid produces too much of a hormone called thyroxine.  Thyroxine controls the rate our metabolism works and the amount of energy released.  Hyperthyroidism is when there is too much thyroxine produced and released which results in the our metabolism working too much and too much energy being released.


Hyperthyroidism has many possible symptoms.  As a result of the multiple symptoms that are common in many conditions, hyperthyroidism can be hard to diagnose.  Symptoms of hyperthyroidism include: sudden weight loss despite normal eating habits, rapid heart rate, sweating, tremors, nervousness, anxiety, thinning skin, fatigue, muscle weakness, brittle hair, swelling of the neck, difficulty sleeping, and irritability.


Hyperthyroidism can be caused by several different things.  Grave's disease, thyroiditis, Plummer's disease, and toxic adenoma can all cause hyperthyroidism.


There are a few treatment options and some depend on the cause.  First is radioactive idoine taken orally.  This causes the thyroid gland to shrink making symptoms shrink.  Second, anti-thyroid medication prevents the thyroid from creating an excess of hormones which will help prevent symptoms.  Third, is surgery which is an option if other treatments do not work.  In a thyroidectomy a surgeon removes part of the thyroid.  There are other options of treatment but those are the main three.
