| 설명 | 적혈구의 기능은 산소를 운반하는데 있다. 적혈구 속에 산소와 결합을 하여 산소를 운반하는 혈색소라는 물질이 있다. 철은 이 혈색소의 중요한 부분을 이루는 것으로 철이 없으면 혈색소가 만들어질 수가 없다. 혈색소가 없으면 역시 적혈구도 만들어지지 않으므로 체내에 철이 부족하면 빈혈이 생긴다. 이 철결핍성 빈혈은 빈혈의 원인 중에서 가장 흔한 것이다(약 25%를 차지한다). 철저장량의 저하-결핍, 혈청철농도의 저하, 트란스페린량 상승, 트란스페린포화도의 저하, 혈색소농도 또는 헤마토크리트의 저하, 저색소성대적혈구를 특징으로 하는 빈혈로서, 생체 내에서 철이 장기에 걸쳐 결핍되며 그 때문에 혈색소 생산 감소에 의해 일어난다. 창자에서의 철흡수량 부족, 철의 수요 증대(유아기, 사춘기, 임신), 철소실과잉(출혈)에 의해 일어나며, 특히 사춘기에서 폐경기까지의 여성에게 많다. 증상으로서는 얼굴창백, 피로감, 피부창백, 손톱 변화(스푼 모양) 등을 나타낸다. 구강 영역에서는 혀의 접촉통, 발적, 건조감, 삼킴곤란을 수반하면 플러머-빈슨(Plummer-Vinson)증후군이라고 한다. 혈액 소견은 혈청철은 저하하며, 철결합능력의 상승, 저색소성 작은적혈구성을 나타낸다. |
