Through the hormones it produces, the thyroid gland influences almost all of the metabolic processes in your body.  Thyroid disorders can range from a small, harmless goiter (enlarged gland) that needs no treatment to life-threatening cancer.  The most common thyroid problems involve abnormal production of thyroid hormones.  Too much of these vital body chemicals results in a condition known as hyperthyroidism.  Too little hormone production leads to hypothyroidism.

Although the effects can be unpleasant or uncomfortable, most thyroid problems can be managed well if properly diagnosed and treated.
