Anemia can be characterized by continuous reduction of red blood cells in blood. In other words, when the normal amount of hemoglobin in blood drops down that leads to anemia. The normal level differs in male and female blood. In case of male when the hemoglobin level falls down the amount of 13.5 gram/100 ml the male may said to develop anemia. On the other hand, whenever the hemoglobin level in female blood drops down the amount of 12.0 gram/100 ml the female can be said to develop anemia.
Causes of anemia
Any factor that leads to the destruction of red blood cells can be regarded as the cause of anemia. A red blood cell may live up to 120 days normally. Sometimes these red blood cells die before that normal life span and that in turn leads to develop anemia. However, two most significant causes of anemia are –
- constant downfall in the normal production of red blood cells or hemoglobin in blood
- constant up-rise in the destruction of red blood cells in blood
Classification of Anemia
There are three common types of anemia, namely the microcytic anemia, the normocytic anemia and the macrocytic anemia. These different types of anemia are defined by the MCV or Mean Corposcular Volume which monitors the normal balance of red blood cells.
The microcytic anemia occurs when the MCV drops down 80.
The normocytic anemia occurs when the MCV stays between 80 and 100.
The macrocytic anemia occurs when the MCV is high.
