Dr. E’s Women’s Health Update:  Crossing your T’s when it comes to thyroid health
Three essential thyroid hormones play important roles in how a woman’s body functions. Do you know your three T’s? 

Hello friends, 

Three hormones released by the thyroid gland control multiple physiological activities in a woman’s body. It is important for all women to understand these essential hormones and how they impact your health and well-being.

In the context of thyroid function, T3 (triiodothyronine) and T4 (thyroxine) are two crucial hormones produced by the thyroid glad that play essential roles in regulating metabolism and other bodily functions. Reverse T3 (rT3) is a biologically inactive form of T3 produced from T4 under certain conditions. Here is a brief overview of each:

T3 (Triiodothyronine):
T3 is the more biologically active form of thyroid hormone, and it is responsible for regulating the body's metabolism, heart rate, and body temperature. It plays a crucial role in ensuring that cells have enough energy to function properly. T3 is produced directly by the thyroid gland and is also converted from T4 in various tissues.
T4 (Thyroxine):
T4 is the primary hormone produced by the thyroid gland, and it serves as a precursor to T3. It is converted to T3 in various tissues through the action of enzymes known as deiodinases. T4 plays a critical role in maintaining overall thyroid hormone levels and ensuring proper thyroid function.
Reverse T3 (rT3):
Reverse T3 is an inactive form of T3 produced from T4 in times of stress or illness. It competes with T3 for binding to thyroid receptors but does not exert the same biological effects. Elevated levels of rT3 relative to T3 can occur in certain conditions, such as severe illness or chronic stress, and may indicate a disruption in the normal conversion of T4 to T3.

Measuring T3, T4, and rT3 levels can provide valuable insights into thyroid function and can help in the diagnosis and management of thyroid disorders such as hypothyroidism, hyperthyroidism, or just a weakened thyroid hormone production. It is important for a woman’s health to have these levels checked out, a test we can provide here at Age Rejuvenation.
