“When the thyroid underperforms, people often feel tired, gain weight, get cold easily, or even feel depressed. These symptoms can make life tough, so doctors often prescribe levothyroxine to ...
Levothyroxine, also known as L-thyroxine, is a synthetic form of the thyroid hormone thyroxine (T 4). [5] [8] It is used to treat thyroid hormone deficiency (hypothyroidism), including a severe form known as myxedema coma. [5]
Numerous symptoms and signs are associated with hypothyroidism and can be related to the underlying cause, or a direct effect of not having enough thyroid hormones. [15] [16] Hashimoto's thyroiditis may present with the mass effect of a goiter (enlarged thyroid gland). [15] In middle-aged women, the symptoms may be mistaken for those of ...

For patients taking levothyroxine, TSH may be boosted by discontinuing levothyroxine for 3–6 weeks. [6] This long period of hormone withdrawal is required because of levothyroxine's relatively long biological half-life, and may result in symptoms of hypothyroidism in the patient. The shorter half-life of liothyronine permits a withdrawal ...
This may be used in those with very large thyroids or when cancer is a concern. [1] In the United States hyperthyroidism affects about 1.2% of the population. [3] Worldwide, hyperthyroidism affects 2.5% of adults. [8] It occurs between two and ten times more often in women. [1] Onset is commonly between 20 and 50 years of age. [2]
Myxedema psychosis is a relatively uncommon consequence of hypothyroidism, such as in Hashimoto's thyroiditis or in patients who have had the thyroid surgically removed and are not taking thyroxine. A chronically under-active thyroid can lead to slowly progressive dementia , delirium , and in extreme cases to hallucinations , coma , or ...
