Anemia Anemia is a condition characterized by too little hemoglobin or too few red blood cells in the blood. It is considered a symptom of an underlying disease or condition rather than a disease itself. The most common causes of anemia are deficiencies of iron, vitamin B12 and folic acid.
Anemia occurs when there is too little iron stored in the body.
If you suspect that you have anemia, it's important to visit your doctor. Anemia can weaken body's resistance to illness or injury, and limits your energy and productivity. It can also indicate a more serious medical condition. Anemia is confirmed through a blood test. Treatment for anemia may be iron supplements or injections.
