A thyroid disease is a condition that causes the thyroid gland which is located within our neck to function abnormally producing either too little or too much of the thyroid hormones that are essential for the regulation of our body's metabolism. The thyroid gland is prone to numerous diseases and disorders that can cause hyperthyroidism which is the overproduction of thyroid hormones and hypothyroidism which is the underproduction of thyroid hormones.
