   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] It may also be used to treat and prevent certain types of thyroid tumors. [5] It is not indicated for weight loss. [5]

   Thyroxine or tetraiodothyronine (T4) is produced by the thyroid gland. The term is sometimes used to refer to hyperthyroidism, but hyperthyroidism is a more general term. [2] When the level of thyroxine (T4) in the blood exceeds normal range, it can lead to symptoms such as irritability and unexplained weight loss. [3] Types include:

   When pregnant, a woman with a low-functioning thyroid will also need to increase her dosage of thyroid hormone.

[32] Although the evidence for doing so is not definitive, treatment of elderly persons having subclinical hyperthyroidism could reduce the number of cases of atrial fibrillation ...

8. Hypothyroidism - Wikipedia

   The gland increases in size by 10%, thyroxine production increases by 50%, and iodine requirements increase. Many women have normal thyroid function but have immunological evidence of thyroid autoimmunity (as evidenced by autoantibodies) or are iodine deficient, and develop evidence of hypothyroidism before or after giving birth.

9. Thyrotoxic periodic paralysis - Wikipedia

   The abnormality in the channel is thought to lead to shifts of potassium into cells, under conditions of high thyroxine (thyroid hormone) levels, usually with an additional precipitant. Treatment of the low levels of potassium in the blood, followed by correction of the hyperthyroidism, leads to complete resolution of the attacks.
