An overview of thyroid diseases
The thyroid is an endocrine gland situated in the neck at the level of the cricoid cartilage at the base of the larynx and extending from the level of the fifth cervical vertebra down to the first thoracic. It is butterfly shaped with 2 elongated lateral lobes with superior and inferior poles connected by a median isthmus. The gland contains two hormones, L-thyroxine (tetraiodothyronine, T4) and L-triiodothyronine (T3). Affecting between one and two percent of the population worldwide, thyroid disease is among the most common endocrine disorders. Thyroid disorders and thyroid cancer disproportionately affect women.
