Thyroid Disorders & Surgery

The thyroid gland is a butterfly-shaped organ located in the front of the neck, just over
the windpipe. It produces iodine-containing hormones which regulate the rate at which
body cells use energy and produce heat.

The growth and development of all the body's tissues are dependent on the thyroid
gland's proper functioning. If the thyroid gland is either overactive or underactive, it
can create health problems.
