Thyrotoxicosis factitia
Thyrotoxicosis factitia
Thyrotoxicosis factitia (pronunciation: thy-ro-tox-i-cosis fac-ti-tia) is a medical condition characterized by an overactive thyroid gland due to the ingestion of excessive amounts of thyroid hormone.
Etymology
The term "thyrotoxicosis factitia" is derived from the Greek words "thyreos" (shield), referring to the thyroid gland's shield-like shape, "toxicos" (poison), indicating the toxic effect of excessive thyroid hormone, and the Latin "factitia" (artificial), referring to the condition's artificial origin.
Definition
Thyrotoxicosis factitia is a form of hyperthyroidism that is caused by the ingestion of excessive amounts of thyroid hormone, often in the form of thyroid hormone medication. Unlike other forms of hyperthyroidism, thyrotoxicosis factitia is not caused by an overactive thyroid gland, but rather by the ingestion of too much thyroid hormone.
Symptoms
Symptoms of thyrotoxicosis factitia are similar to those of other forms of hyperthyroidism and may include rapid heart rate, weight loss, nervousness, irritability, and tremors. However, because the condition is caused by the ingestion of thyroid hormone, symptoms may be more severe and may include severe weight loss, heart palpitations, and even heart failure.
Diagnosis
Diagnosis of thyrotoxicosis factitia is typically made through a combination of physical examination, patient history, and laboratory tests. Laboratory tests may show elevated levels of thyroid hormone in the blood, but low or undetectable levels of thyroid-stimulating hormone (TSH).
Treatment
Treatment for thyrotoxicosis factitia involves discontinuing the ingestion of excessive amounts of thyroid hormone. In some cases, medication may be needed to control symptoms until thyroid hormone levels return to normal.
