Thyroid Hormone Absorption

Meaning

Thyroid Hormone Absorption refers to the crucial physiological process by which orally administered synthetic or desiccated thyroid hormones, primarily levothyroxine (T4) and liothyronine (T3), are transported from the gastrointestinal tract into the bloodstream. This process is highly variable and can be significantly influenced by concurrent medications, dietary components, and underlying gastrointestinal health. Optimized absorption is paramount for achieving and maintaining stable, therapeutic serum concentrations of active thyroid hormone. Inconsistent absorption can lead to persistent hypothyroid symptoms.
