Thyroid: What Is Triiodothyronine?

By    |   Thursday, 24 Mar 2016 09:09 PM

The thyroid gland produces hormones that control body functions and metabolism. The main hormones produced are called triiodothyronine and thyroxine.

A key part of the endocrine system, the thyroid gland is the control center for a vast array of bodily functions. It uses iodine in the body to produce thyroxine or T4, said You and Your Hormones.

Thyroxine is then converted into its active form called triiodothyronine or T3. A small amount of triiodothyronine is secreted into the blood directly by the thyroid gland, but the majority of it is converted from thyroxine in the liver and kidneys.

According to You and Your Hormones, the thyroid works on a feedback loop with the pituitary gland and the hypothalamus which sits at the base of the brain. The hypothalamus releases a hormone that causes the pituitary gland to release thyroid-stimulating hormone (TSH).

Thyroid-stimulating hormone in turn causes the thyroid gland to produce triiodothyronine and thyroxine.

Healthline reported that T3, together with T4, is responsible for regulating metabolism, body temperature, and heart rate.

If the thyroid gland is overactive (hyperthyroidism), it produces too much triiodothyronine and thyroxine. Too much of these thyroid hormones results thyrotoxicosis, said Hormone Health Network.

Hyperthyroidism can be caused by autoimmune disease, tumors on the thyroid gland, or enlargement of the thyroid gland called goiter.

This condition can cause irregularities in the menstrual cycle, irritability, weight loss, intolerance to heat, and an increase in bowel movement frequency.

Underproduction of triiodothyronine and thyroxine is called hypothyroidism. This condition is most often caused by an autoimmune disease called Hashimoto’s thyroiditis, but iodine deficiency or certain prescription medications can also be to blame, explained You and Your Hormones.

Symptoms of hypothyroidism include weight gain, low mood, fatigue, low heart rate, and intolerance to cold.

Thyroid disorders like hyperthyroidism and hypothyroidism can be diagnosed with a series of simple blood tests. If a thyroid disorder is confirmed, physicians can develop the appropriate treatment plan.
