❗The thyroid gland is an important part of the endocrine system, secreting a number of hormones that affect everything from heart health to metabolism. One of those hormones is thyroxine, also known as T4. Because of the many functions that thyroxine impacts, it is considered one of the most important thyroid hormones. Understanding thyroxine is crucial to protecting your overall health.
Thyroxine is a hormone the thyroid gland secretes into the bloodstream. Once in the bloodstream, thyroxine travels to the organs, like the liver and kidneys, where it is converted to its active form of triiodothyronine. Thyroxine plays a crucial role in heart and digestive function, metabolism, brain development, bone health, and muscle control. It affects almost all of the body's systems, which means proper thyroxine levels are vital for health. This is why many doctors will test T4 levels along with the more common T3 levels when testing for thyroid disorders.
Having too little thyroxine or too much thyroxine can cause health problems. If your body releases too much thyroxine, you will suffer a condition called thyrotoxicosis. This can cause a goiter, which is a swelling of the neck because of an enlarged thyroid gland. Thyrotoxicosis can also cause menstrual irregularities, an increase in bowel movements, weight loss, heat intolerance, fatigue, and irritability. Thyrotoxicosis is commonly caused by hyperthyroidism, tumors in the thyroid gland, or thyroid inflammation.
The body can also produce too little thyroxine, a condition known as hypothyroidism. Low thyroxine levels cause problems with development if it occurs when an individual is young. In adults, thyroxine deficiency will lower the metabolic rate, causing weight gain, memory problems, infertility, fatigue, and muscle stiffness. ❗
