认识慢性肾病贫血

ID: ANH20232chis
医疗动画文字记录:你或你关心的人可能已经被诊断为慢性肾病贫血,CKD贫血。这段视频将帮助你更多地了解CKD贫血以及它是如何影响你的身体的。当你没有足够的红细胞时,就会发生贫血。红细胞是在被称为骨髓的骨骼中心产生的。在红细胞中,铁是制造一种携带氧气的蛋白质——血红蛋白所必需的。红细胞通过血液流到肺部获取氧气。当血液流经肺部时,氧气从肺泡进入血液。然后,氧气附着在红细胞中的血红蛋白上。这些红细胞向全身的细胞输送氧气。细胞需要氧气来工作和生存。在贫血时,没有足够的健康红细胞向身体输送氧气。这意味着器官和组织可能没有发挥应有的作用。虽然许多情况可能导致贫血,但它往往是由慢性肾病引起的。肾脏产生一种叫做促红细胞生成素(EPO)的激素。骨髓利用促红细胞生成素制造红细胞。慢性肾病会损害肾脏,导致肾脏无法产生足够的促红细胞生成素。因此,骨髓产生的红细胞减少,导致贫血。CKD贫血的症状可能包括疲乏或虚弱、面色苍白、头痛、注意力不集中、食欲不振、胸痛、心跳加快、站起来时感到头晕、活动时呼吸短促。医生可能会检查你的血液样本,以诊断是否患有CKD贫血。例如,一个全血细胞计数检测可以测量样本中血红蛋白和红细胞的量。健康成年人的正常血红蛋白范围为:男性13.8 - 17.2,女性12.1 - 15.1。慢性肾病患者的血红蛋白水平男性低于13,女性低于12。医生可能会进行其他检测来评估CKD贫血。如果你对CKD贫血有疑问,包括什么时候开始治疗,或任何已经开的药物,请咨询医生。遵医嘱服药并报告所有副作用是很重要的。
