                                Historically, pernicious anemia, a severe form of B12 deficiency, was often fatal before effective treatments were discovered. Today, while a B12 deficiency does not directly cause death, leaving it unaddressed can lead to serious, life-threatening health complications. This risk makes early diagnosis and proper management critically important.
