Hyperthyroidism is the term to describe activity of the Endocrine System that affects the Thyroid where “over-active” causes several medical problems and complications.

Normally the thyroid gland allows for balance of thyroid hormones.

But in Hyperthyroidism, the Thyroid Gland produces a high level, specifically in excess, of thyroid hormones thyroxine and triiodothyronine (T4 and T3 respectively)

Metabolism and other body functions are closely associated with thyroid hormones.

When the thyroid is “underactive” it is called Hypothyroidism.
