Anemia, one of the more common blood disorders, occurs when the level of healthy red blood cells (RBCs) in the body becomes too low. This can lead to health problems because RBCs contain hemoglobin, which carries oxygen to the body's tissues. anemia can cause a variety of complications, including fatigue and stress on bodily organs.
Anemia can be caused by many things, but the three main bodily mechanisms that produce it are:
- excessive destruction of RBCs
- blood loss
- inadequate production of RBCs
Among many other causes, anemia can result from inherited disorders, nutritional problems (such as an iron or vitamin deficiency), infections, some kinds of cancer, or exposure to a drug or toxin.
