    症状
    如果出现严重或持续的新症状，请联系医疗服务提供商。

    贫血的症状因贫血原因而异。它可能包括：

    • 疲劳
    • 马莱塞
    • 全身无力
    • 苍白的皮肤
    • 冰冷的手和脚
    • 头晕
    • 免疫力下降
    • 呼吸急促

    原因

    贫血是由红细胞减少引起的。造成这种情况的原因有:

    • 减少血红细胞的生成，如缺铁性贫血或巨幼细胞性贫血
    • 失血过多：失血可由外部出血(如道路交通事故)，或内出血(如十二指肠感染)、经期出血、长期服用阿司匹林或止痛药等引起
    • 红细胞破坏：溶血性贫血
    • 自身免疫性疾病，如风湿性关节炎

    预防

    贫血的少数原因，如缺铁性贫血或巨幼红细胞性贫血，可以通过以下方式进行预防：

    • 食用富含铁的健康饮食
    • 消耗维生素B12和叶酸
    • 增加维生素C的摄入量，因为它有助于更好地吸收食物中的铁
    • 减少茶和咖啡的摄入量，因为它会减少对食物中铁的吸收

    并发症

    • 当贫血非常严重时，可能会导致严重的易疲劳感，使其难以完成日常活动。
    • 贫血，尤其是由于叶酸缺乏引起的贫血，可导致怀孕期间的出现各种并发症，包括婴儿发育不良和早产
    • 贫血会导致心跳加快或不规则。在贫血的情况下，心脏必须泵送更多的血液以弥补血液中的氧气不足。这将导致心脏体积增大或心力衰竭。
    • 失血过多，如在道路交通事故中，可导致非常严重的贫血，并且可能是致命的
