What Is Anemia?

December 12, 2012

Anemia is a condition that develops when your blood lacks enough healthy red blood cells or hemoglobin. Hemoglobin is a main part of red blood cells and binds oxygen. If you have too few or abnormal red blood cells, or your hemoglobin is abnormal or low, the cells in your body will not get enough oxygen. Symptoms of anemia – like fatigue – occur because organs aren’t getting what they need to function properly.¬†

There are many types of anemia. All are very different in their causes and treatments. Iron-deficiency anemia, the most common type, is very treatable with diet changes and iron supplements. Some forms of anemia – like the anemia that develops during pregnancy — are even considered normal. However, some types of anemia may present lifelong health problems.

There are more than 400 types of anemia, which are divided into three groups:

  • Anemia caused by blood loss
  • Anemia caused by decreased or faulty red blood cell production
  • Anemia caused by destruction of red blood cells
