Other causes include viruses, and treatment for hypothyroidism where the patient is taking too high a dose of thyroxine. Depending on the cause of high thyroxine levels, treatment might include medications to temporarily reduce T4.

Hypothalamus secretes thyrotropin-releasing hormone which, in turn, stimulates the pituitary gland to produce thyroid stimulating hormone. This hormone stimulates the production of the thyroid hormones, thyroxine and triiodothyronine, by the thyroid gland.

If the whole gland most be removed, patients would then require supplementary T4, since having too little thyroxine is just as dangerous as having too much.

Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones. Alternative names for thyroxine T4; tetraiodothyronine; thyroxin.

What happens if I have too little thyroxine? Too little production of thyroxine by the thyroid gland is known as hypothyroidism. It may be caused by autoimmune diseases, poor iodine intake or brought on by the use of certain drugs. Sometimes,

Having high thyroxine levels, or an elevation in T4, principally induces a state of hyperthyroidism. This may cause a variety of symptoms, including weight loss, hair loss, insomnia, and trembling. It is also associated with fatigue, poor tolerance of higher temperatures, and perspiration.
