What is Thyroxine (T4) Deficiency?

Thyroxine (T4) Deficiency is an endocrine disorder that occurs when the thyroid gland does not produce enough of the hormone thyroxine (T4). T4 is essential for the body to function properly, playing a key role in metabolism, energy production, and growth. Without sufficient levels of thyroxine, the body is unable to properly use energy from food, leading to a wide range of health conditions.
