Anemia occurs when you have a level of red blood cells
(RBCs) in your blood that is lower than normal. Iron deficiency anemia is the
most common type of anemia, and it occurs when your body doesn’t have enough of
the mineral iron. Your body needs iron to make a protein called hemoglobin.
This protein is responsible for carrying oxygen to your body’s tissues, which
is essential for your tissues and muscles to function effectively. When there
isn’t enough iron in your blood stream, the rest of your body can’t get the
amount of oxygen it needs. In women of childbearing age, the most common cause of iron
deficiency anemia is a loss of iron in the blood due to heavy menstruation or
pregnancy. A poor diet or certain intestinal diseases that affect how the body
absorbs iron can also cause iron deficiency anemia. Doctors normally treat the
condition with iron supplements or changes to diet.
