A goiter is an enlargement of the thyroid gland which is situated at the front of the throat, below the larynx. It is made up of two lobes on either side of the windpipe, joined in front by an isthmus. The thyroid gland secretes hormones that regulate metabolic processes, such as growth and energy expenditure. This gland is controlled by the pituitary gland, which is located in the brain. The pituitary prompts the thyroid to make its hormones including thyroxine (T4) and tri-iodothyronine (T3) by releasing a thyroid stimulating hormone (TSH). However, if a persons diet is too low in iodine the thyroid can't manufacture hormones. Never the less the pituitary keeps sending chemical messages to the thyroid, without any result . The thyroid gland then enlarges as it unsucsesfuly trys tos to comply with the pituitary's glands instruction. Apart from iodine deficiency, other causes of goiter involve conditions of the thyroid - such as nodules, cancer, hyperthyroidism and hypothyroidism.
The symptoms of a goiter include: * Enlargement of the throat, ranging from a small lump to a huge mass. * Swallowing problems, if the goiter is large enough to press on the esophagus. * Breathing problems, if the goiter is large enough to press on the windpipe (trachea).

∙ 13y agoIt is both hyper thyroid and hypothyroid disease.
Hypothyroid
Thyroid stimulating (TSH) and releasing hormones (TRH) are regulated by thyroid hormone. In hypothyroidism there is no regulation so TSH and TRH increase above normal levels. In normal people this would be an indication of low iodine levels causing the body to hang on to all iodine. Ordinarily the iodine would be used to make thyroid hormone, but in hypothyroidism it collects in the colloid and forms a goitre.
Treatment: Thyroxin (thyroid hormone) will inhibit production of TSH and TRH.
Hyperthyroid
A hyperthyroid goitre is caused by over activation of the thyroid gland. This is usually caused by an autoimmune condition that is stimulating thyroid hormone production in absence of TSH (Grave's Disease). The increased demand on the thyroid gland causes it to grow.
Note: Goitres are filled with connective tissue. Even if you cure the thyroid condition the goitre may remain.

Did the result of thyroidectomized rat indicate hyperthyroidism or hypothyroidism?
There is no longer a thyroid, so it results in hypothyroid.
What is thyroydism?
There is Hypothyroidism- low amounts thyroid hormone, and Hyperthyroidism- high amounts of thyroid hormone
Is propylthiouracil used for hypothyroidism or hyperthyroidism?
Propylthioracil (PTU) is used in the treatment of some hypERthyroid conditions.
What is the medical term meaning hypersercretion of thyroxine?
Hyperthyroidism is overactivity of the thyroid, and hypothyroidism is undersecrection.
How can you have a multinodular goiter on your thyroid but normal blood tests so no treatment needed and some physical symptoms of hypothyroidism?
Symptoms of hypothyroidism:- * Tiredness * Fatigue * Cold intolerance * Constipation * Decreased appetite * Dry skin and hair * Confusion Basically a slowing down of the entire body, most systems are affected. Multinodular goitre: Can be present in hyperthyroidism, which is the complete opposite of the symptoms above, in toxic multinodular goitre. Treatment for a euthyroid (normal tests) multinodular thyroid is recommended to be surgery if required, as giving thyroid hormones (T4) is shown not to be beneficial.
