概述信息
铁是一种矿物。体内的大部分铁存在于红细胞的血红蛋白和肌肉细胞的肌红蛋白中。铁是运输氧气和二氧化碳所必需的,并且在体内还有其他重要作用。铁最常用于预防和治疗由低铁水平引起的贫血。也用于月经期(月经过多)和怀孕期间异常大量出血引起的贫血。
它是如何工作的?
铁有助于红细胞将氧气从肺部输送到全身的细胞。铁还在体内的许多重要功能中发挥作用。
缺铁指南
铁可以帮助您的身体通过血液获取氧气。没有铁可以制造的红细胞更少,铁会导致贫血。由于出血、月经过多或其他问题(如溃疡),铁水平可能会变得过低。它也可能是由于没有通过饮食获得足够的铁引起的。缺铁的常见症状包括疲劳、头晕、喜怒无常和其他症状。治疗包括服用铁补充剂。点击下面的链接,查找 WebMD 对缺铁症如何导致、如何治疗等的全面报道。

Iron IV Infusion
This medicine treats "iron-poor" blood (anemia) in people with long-term kidney disease. You may need extra iron because of blood loss during kidney dialysis. Your body may also need more iron if you use erythropoietin to help make new red blood cells. Iron is an important part of your red blood cells and is needed to transport oxygen. Many patients with kidney disease cannot get enough iron from food and require injections.
Iron is a mineral. Most of the iron in the body is found in the hemoglobin of red blood cells and the myoglobin of muscle cells. Iron is needed for transporting oxygen and carbon dioxide and has other vital roles in the body. Iron is most commonly used to prevent and treat anemia caused by low iron levels. It is also used for anemia caused by abnormal heavy bleeding during menstrual periods (menorrhagia) and pregnancy.
Iron helps red blood cells carry oxygen from the lungs to cells all over the body. Iron also plays a role in many vital functions in the body.
Mild iron deficiency anemia often isn't noticeable.
When it gets more severe, you may have these symptoms
Fatigue or weakness
Pale or yellow skin
Shortness of breath
Dizziness or lightheadedness
Headaches
Cold feet and hands
Brittle, cracked nails, spoon-shaped nails
Hair loss
Cracks near the side of your mouth
Pica (cravings for things that aren't food, like dirt, starch, clay, or ice)
Sore and swollen tongue
It can happen if you don't eat enough foods containing iron, your body can't properly absorb iron, you lose iron through your blood, or you’re pregnant.
