What Could Be Causing Your Anemia? 10 Possible Reasons

4. Iron Deficiency

Iron deficiency anemia is among the most common types of anemia. It develops when there is too little iron in the body. The most common cause of iron deficiency anemia is blood loss, although in some cases it is caused by poor absorption of iron. Increasing iron intake is fairly simple. By incorporating leafy greens and cooking with cast iron, one can increase consumption of this essential mineral. However, animal sources (ie meat, fish) contain "heme iron," which is better absorbed in the body compared to "non-heme iron" from plant sources. Iron supplements are also available.
