Overview of Iron Deficiency Anemia

Iron deficiency anemia is a condition where the body lacks enough healthy red blood cells due to insufficient iron levels. Since iron is essential for producing hemoglobin and the substance that carries oxygen in the blood and low iron levels can lead to fatigue, weakness, and other health issues. It is one of the most common types of anemia worldwide.

Types of Iron Deficiency Anemia

1. Iron Deficiency Anemia: Caused by low iron levels.

2. Anemia of Chronic Disease: Occurs due to long term health conditions affecting red blood cell production.

3. Pernicious Anemia: Related to vitamin B12 deficiency.

4. Aplastic Anemia: A rare form where the bone marrow does not produce enough blood cells.

5. Hemolytic Anemia: Caused by the destruction of red blood cells.
