Nontoxic nodular goiter
Nontoxic Nodular Goiter
Nontoxic nodular goiter (pronunciation: non-tox-ic nod-u-lar goi-ter) is a medical condition characterized by the enlargement of the thyroid gland without causing an overproduction of thyroid hormone or any toxic effects.
Etymology
The term 'nontoxic nodular goiter' is derived from the following components: 'non-toxic' meaning not harmful, 'nodular' referring to the presence of nodules or lumps, and 'goiter' which is a term used to describe an enlarged thyroid gland.
Definition
Nontoxic nodular goiter is a type of thyroid disorder where the thyroid gland, located in the neck, becomes abnormally enlarged and forms nodules. Despite the enlargement, the thyroid gland does not produce excessive amounts of thyroid hormone, hence the term 'nontoxic'.
Symptoms
Symptoms of nontoxic nodular goiter may include a visible swelling at the base of the neck, difficulty swallowing or breathing, and a feeling of tightness in the throat. However, many individuals with this condition may not experience any symptoms.
Causes
The exact cause of nontoxic nodular goiter is unknown. However, it is believed to be associated with a lack of dietary iodine, which is essential for the production of thyroid hormones. Other potential causes include genetic factors and environmental influences.
Treatment
Treatment for nontoxic nodular goiter may involve observation, thyroid hormone suppression therapy, or surgery, depending on the size of the goiter and the severity of the symptoms.
