缺铁性贫血(iron deficiency anemia, IDA)是由于体内储存铁缺乏而影响血红蛋白合成所引起的一种常见贫血。这种贫血特点是骨髓、肝、脾及其他组织中缺乏可染色铁,血清铁浓度和血清转铁蛋白饱和度均降低。典型病例贫血是属于小细胞低色素型。铁缺乏症根据体内缺铁的发展过程,分体内储存铁耗尽(iron depletion,ID)、缺铁性...
缺铁性贫血是指体内铁含量不足时发生的贫血。患贫血时,人的红细胞(RBC)数量比正常人低。 红细胞内的血红蛋白担负者向全身输送氧气的功能。铁是合成血红蛋白的重要原料。铁不足时,血红蛋白和红细胞生成减少,从而导致贫血。补铁治疗通常会使贫血好转。 体征和症状 初期,缺铁性贫血的儿童可能没有任何症状。如果未能及...
缺铁性贫血(iron deficiency anemia,IDA) 铁和红细胞之间的关系:(此内容了解即可) 机体通过严格的调节机制维持铁平衡(因为高负荷铁会产生过量的氧自由机对机体造成损害)。 铁的吸收率取决于机体的铁储备(铁储备调节)和红细胞生成速率(红系生成调节)。 铁储备多时,铁吸收率低。反之铁的吸收率高。 红细胞生在旺盛...

An iron deficiency is most commonly linked to the development ofanemia, which is a condition when there’s a lack of healthy red blood cells being produced. Iron helps metabolize proteins and plays a role in the production of hemoglobin and red blood cells, helping to prevent anemia from form...
Iron deficiency anemia is one of the most prevalent nutritional deficiencies, worldwide. The objective of this article is to inform practitioners on salient features of this condition. This review article covers the causes of iron deficiency, the diagnosis and the various treatment options available....
Posthemorrhagic anemia is discussed in this article because it is an important cause of iron deficiency. The acute and potentially catastrophic problems of hypoxia and shock that can occur from significant hemorrhage or severe iron deficiency are discussed elsewhere; however, daily blood losses can be...
