Hypothyroidism (also called underactive thyroid, low thyroid or hypothyreosis) is a disorder of the endocrine system in which the thyroid gland does not produce enough thyroid hormones. [3] It can cause a number of symptoms, such as poor ability to tolerate cold, extreme fatigue, muscle aches, constipation, slow heart rate, depression, and ...
Most often, the entire gland is overproducing thyroid hormone. Less commonly, a single nodule is responsible for the excess hormone secretion, called a "hot" nodule. Thyroiditis (inflammation of the thyroid) can also cause hyperthyroidism. [24] Functional thyroid tissue producing an excess of thyroid hormone occurs in a number of clinical ...
Goiter is the general enlargement of the thyroid that can be associated with many thyroid diseases. The main reason this happens is because of increased signaling to the thyroid by way of TSH receptors to try to make it produce more thyroid hormone. [9] This causes increased vascularity and increase in size (hypertrophy) of the gland. [9]
Levothyroxine, a drug used to treat hypothyroidism, can lead to reduced bone mass and density in older adults with normal thyroid levels, a small cohort study has shown.

Around the world, the most common cause of congenital iodine deficiency syndrome (endemic cretinism) [1] is dietary iodine deficiency. Iodine is an essential trace element, necessary for the synthesis of thyroid hormones. Iodine deficiency is the most common preventable cause of neonatal and childhood brain damage worldwide. [11]
The last option for TM treatment includes surgical removal of portions of the thyroid which can also be performed to restore thyroid homeostasis. This treatment option usually is done when overproduction of TM is caused by a toxic multinodular goiter. Since these goiters enlarge the thyroid and can cause the patient to become physically ...
One common cause of this is the presence of maternal antibodies that temporarily impair thyroid function for several weeks. [ 5 ] The word "cretinism" is an old term for the state of mental and physical retardation resulting from untreated congenital hypothyroidism, usually due to iodine deficiency from birth because of low iodine levels in the ...
