Iron Deficiency (Low Iron) Signs & Symptoms


Iron deficiency is a condition that occurs when the body does not get a sufficient supply of iron. The body requires iron to function properly. Red blood cells in your body depend on iron to make hemoglobin, the compound that enables the blood to carry oxygen around the body.

A deficiency in iron means your muscles and tissues will not be able to get enough oxygen to work efficiently. Low iron in the blood results in a condition known as iron deficiency anemia which children and pregnant women [1] are especially at risk of.

Iron deficiency is caused by a shortage of iron in one’s regular diet, loss of blood during periods or through injury, inflammatory bowel disease, or increased iron demand during pregnancy.
