Iron Deficiency

ferritinWhat Is Iron?

[dropcap]I[/dropcap]ron is an essential mineral that is required for normal body function.

Almost two-thirds of iron in the body is found in hemoglobin, the protein in red blood cells that carries oxygen to tissues. Smaller amounts of iron are found in myoglobin, a protein that helps supply oxygen to muscle, and in enzymes that assist biochemical reactions.

Iron is also found in proteins that store iron for future needs and that transport iron in blood.

Q: How are iron stores regulated?

A:Iron stores are regulated by intestinal iron absorption.1That is, whenever iron is needed, more iron is absorbed than when iron is sufficient. This mechanism prevents excess iron in the body which is harmful.

In the brain, iron is necessary to ensure oxygenation and to produce energy in the cerebral parenchyma (via cytochrome oxid. ase), and for the synthesis of neurotransmitters and myelin.

Iron concentrations in the umbilical artery are critical during the development of the fetus, and in relation with the IQ in the child.2

What Is Folic Acid Or Folate Deficiency Anemia?

[dropcap]F[/dropcap]olic acid deficiency anemia, also called folate deficiency anemia, is a macrocytic anemia characterized by defective DNA synthesis of red blood cells that results from a lack of folate in the body.

Q: How does folate deficiency cause anemia?

A: Folates are a family of B vitamins and folic acid is an active form.

Folate is required for the formation of both red and white blood cells in the bone marrow and for their maturation.

Also, folate serves as a carrier in the formation of heme, which contains iron, and is the non-protein part of the hemoglobin molecule.1

Red blood cells provide oxygen to body tissues. When there are not enough red blood cells or when they cannot properly carry oxygen, the condition is called anemia. In folic acid deficiency anemia, the red blood cells are abnormally large. Such cells are called macrocytes (macro size cells). They are also called megaloblasts (mega size cells) as seen in the bone marrow where they are produced. This is why this macrocytic anemia is also called megaloblastic anemia.2

Tests that may be done to determine folate adequacy are complete blood count (CBC), red blood cell folate level, methylmalonic acid level, and homocysteine level. Folic acid deficiency anemia shows a decrease in red blood cell folate and/or serum folate levels and normal plasma methylmalonic acid level with elevated homocysteine blood level. These levels distinguish folic acid deficiency anemia from vitamin B12 deficiency anemia.3
