Why doesn't the Thalassemia trait become more concerning with age?

Thalassemia trait, typically a genetic condition characterized by reduced hemoglobin production, usually doesn't worsen with age because it is a stable genetic trait. Individuals with thalassemia trait often maintain sufficient hemoglobin levels for normal function and experience few, if any, symptoms throughout their lives. While some may develop mild anemia, this does not typically progress to more severe forms or complications as they age. Regular check-ups can help manage any potential issues, but the trait itself remains stable.
