Hemoglobin is a substance that flows throughout our bodies in our blood. It is essential to us because it binds with oxygen, allowing the blood to then transport it to where it is needed. The body will usually make all the hemoglobin that it needs, but anemia is a condition where there is not enough hemoglobin present.
Anemia can be caused by things such as a lack of iron, which is needed in order to be able to make hemoglobin. It can also be caused by excessive bleeding, which will cause the body to lose a lot of hemoglobin in the blood.
It is a condition that is fairly easy to treat, but it can be quite serious if left untreated so it should not be approached with complacency.
Anemia Sign #1: Pale Skin
Iron is a metal that is red in color when it reacts with oxygen. It is also an essential part of our diet because it is necessary for helping to make hemoglobin, which allows us to transport oxygen around our bodies. Without it, our bodies would not be able to get the oxygen that it needs to survive.
The redness of the hemoglobin in the blood shows through the skin, helping to give it a reddish glow. With less of this in our blood, our skin becomes paler as a result. This is usually quite visible. Paleness can also be a sign of a wide range of illnesses.
