Hyperthyoidism

By: Ariel Reese

What it is and What Can Cause It

This is overactivity of the thyroid gland, The thyroid gland produces the hormones thyroxine (T4) and triiodothyronine (T3). In most cases of hyperthyroidism, the thyroid gland itself produces too much of these hormones

Reason's For Too Much T4

  1. Graves Disease
  2. Hyperfunctioning thyroid nodules(toxic adenoma, toxic multinodular goiter, and plummer's disease)
  3. Thyroiditis

Treatments

  • Radioactive iodine: Taken by mouth, radioactive iodine is absorbed by your thyroid gland, where it causes the gland to shrink and symptoms to subside, usually within three to six months
  • Anti-thyroid medications: These medications gradually reduce symptoms of hyperthyroidism by preventing your thyroid gland from producing excess amounts of hormones
  • Beta blockers: These drugs are commonly used to treat high blood pressure. They won't reduce your thyroid levels, but they can reduce a rapid heart rate and help prevent palpitations.
  • Surgery (thyroidectomy). If you're pregnant or otherwise can't tolerate anti-thyroid drugs and don't want to or can't have radioactive iodine therapy, you may be a candidate for thyroid surgery, although this is an option in only a few cases
