Anemia means your body doesn't have enough healthy red blood cells to carry oxygen to your organs and tissues. Mild cases cause modest problems, but severe anemia can be life-threatening without treatment.

Anemia means your body doesn't have enough healthy red blood cells to carry oxygen to your organs and tissues. Mild cases cause modest problems, but severe anemia can be life-threatening without treatment.
Anemia happens when there is a decrease in the amount of healthy red blood cells within the body. The main job of red blood cells is to carry oxygen around the body to help get oxygen to the organs and tissues. So if there is a lack of healthy red blood cells available to do this, the body is not going to receive the oxygen it needs to function. There are different levels of severity of anemia ranging from mild anemia where there is a smaller decrease in healthy red blood cell, and even life threatening anemia where the body is less able to function without proper treatment.
