It is a hormone called T4, or thyroxin. What would normally happen is that Thyroid Stimulating Hormone (TSH) from the anterior pituitary would stimulate the thyroid to release T4. When enough T4 is produced, it inhibits TSH, or thyroid stimulating hormone, from being secreted. However if enough T4 is not released to inhibit TSH (probably due to an iodine deficiency), then TSH keeps on secreting, overstimulating the thyroid and causing the swelling known as goiter.

Effects of goiter?
Goiter is an enlargement of the thyroid gland, often caused by iodine deficiency. It can lead to symptoms such as swelling in the neck, difficulty swallowing or breathing, and in severe cases, can affect thyroid hormone production and lead to hypothyroidism. Treatment typically involves addressing the underlying cause, such as iodine supplementation or thyroid hormone replacement therapy.
Why do seafoods prevent goiter?
Seafoods are rich in iodine, a crucial nutrient for thyroid function. Goiter, an enlargement of the thyroid gland, can result from an iodine deficiency. Consuming seafood helps maintain adequate iodine levels in the body, preventing goiter.
Why goiter is more common in women than in men?
Women are more prone to goiter due to hormonal changes during puberty, pregnancy, and menopause, as well as hormonal imbalances, such as thyroid disorders. Estrogen can stimulate the growth of thyroid tissue, leading to an increased risk of goiter in women compared to men. Additionally, women are more likely to develop autoimmune thyroid diseases, which can also contribute to goiter formation.
Name the mineral which prevents goiter disease?
The MINERAL which prevents goiter disease is Iodine
Goiters are a result of a deficiency of what substance in the body?
Goiters are often the result of iodine deficiency in the body. Iodine is necessary for the production of thyroid hormones, and a lack of it can lead to the enlargement of the thyroid gland, causing a goiter.
What is the medical term meaning goiter?
If the amount of stimulating hormone is excessive, the thyroid will both enlarge and secrete too much thyroxin. The result--hyperthyroidism with a goiter. Graves' disease is the most common form of this disorder.
Difference between endemic and colloidal goiter?
Hyperthyroid goiter: If the amount of stimulating hormone is excessive, the thyroid will both enlarge and secrete too much thyroxin. The result--hyperthyroidism with a goiter. Graves' disease is the most common form of this disorder. the level of thyroid hormone is High. Euthyroid goiter: The thyroid is the only organ in the body to use iodine. If dietary iodine is slightly inadequate, too little thyroxin will be secreted, and the pituitary will sense the deficiency and produce more TSH. The thyroid gland will enlarge enough to make sufficient thyroxin. This form of goiter does not alter thyroid function in any significant way (colloid goiter). the level of thyroid hormone is Normal.
What is the disease goitre?
A Goiter is a a swelling or enlargement of the Thyroid Gland.A goiter is a growth on the body that can be either cancerous or benign. Goiters form due to a strong concentration of cells under the skin.
What hormone causes goiters?
Goiter is an enlargement of the thyroid gland, located in the neck. Simple goiter is caused by too little iodine which is available in the hormone thyroxine. Toxic goiter, on the other hand, is caused by exactly the opposite condition, overproduction of thyroxine. Oddly enough, both can often be treated by the administration of iodine in one form or another.
A person with a toxic goiter would have very high levels of what hormone?
Thyroxine
What is Nodular Hyperplasia of the Thyroid?
Hyperplasia of the Thyroid gland occurs as a result of dyshormonogenic goiter, endemic goiter, Graves' disease, or due to multinodular goiter.
Is the simple goiter result from hyperthyroidism or hypothyroidism?
Hyperthyroidism.
What causes a goiter to grow in size?
A goiter grows in size due to an imbalance in thyroid hormone production, which can be caused by iodine deficiency, autoimmune disorders, or other factors affecting the thyroid gland.
What element is known as goiter?
The element known to cause goiter is iodine. A deficiency in iodine can lead to the enlargement of the thyroid gland, a condition known as goiter. Adequate iodine intake is essential for thyroid hormone production.
Effects of goiter?
Goiter is an enlargement of the thyroid gland, often caused by iodine deficiency. It can lead to symptoms such as swelling in the neck, difficulty swallowing or breathing, and in severe cases, can affect thyroid hormone production and lead to hypothyroidism. Treatment typically involves addressing the underlying cause, such as iodine supplementation or thyroid hormone replacement therapy.
How are goiter thyroid and iodine related?
Insufficient iodine in the diet causes thyroid hormone to be produced in less than optimal amounts. This sets the stage for hypothyrodism, and possibly even goiter (if the hypothyroidism is untreated for a significant period of time).
What is the pathophysiology of goiter?
PathophysiologyThe histopathology varies with etiology and age of the goiter. Initially, uniform follicular epithelial hyperplasia (diffuse goiter) is present with an increase in thyroid mass. As the disorder persists, the thyroid architecture loses uniformity, with the development of areas of involution and fibrosis interspersed with areas of focal hyperplasia. This process results in multiple nodules (multinodular goiter). On nuclear scintigraphy, some nodules are hot, with high isotope uptake (autonomous) or cold, with low isotope uptake, compared with the normal thyroid tissue. The development of nodules correlates with the development of functional autonomy and reduction in thyroid-stimulating hormone (TSH) levels. Clinically, the natural history of a nontoxic goiter is growth, nodule production, and functional autonomy resulting in thyrotoxicosis in a minority of patients.Signs / symptomsdyspneastridorHemorrhagebronchitisdysphagia.hoarseness.facial plethoraand dilated neck veins
