Thyroid disorders are conditions that affect the thyroid gland, a butterfly-shaped gland in
the front of the neck. The thyroid has important roles to regulate numerous metabolic processes throughout the
body. Different types of thyroid disorders affect either its structure or function.
The thyroid gland is located below the Adam's apple wrapped around the trachea. A thin area of tissue
in the gland's middle, known as the isthmus, joins the two thyroid lobes on each side.
