What is the definition of Childhood Iron Deficiency Anemia?

Anemia is a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to body tissues. There are many types of anemia.

Iron helps make red blood cells and helps these cells carry oxygen. A lack of iron in the body may lead to anemia. The medical name of this problem is iron deficiency anemia.

What are the alternative names for Childhood Iron Deficiency Anemia?

Anemia - iron deficiency - children

What are the causes for Childhood Iron Deficiency Anemia?

Anemia caused by a low iron level is the most common form of anemia. The body gets iron through certain foods. It also reuses iron from old red blood cells.

A diet that does not have enough iron is the most common cause of this type of anemia in children. When a child is growing rapidly, such as during puberty, even more iron is needed.

Toddlers who drink too much cow's milk may also become anemic if they are not eating other healthy foods that have iron.

Other causes may be:

  • The body is not able to absorb iron well, even though the child is eating enough iron.
  • Slow blood loss over a long period, often due to menstrual periods or bleeding in the digestive tract.

Iron deficiency in children can also be related to lead poisoning.

What are the symptoms for Childhood Iron Deficiency Anemia?

Mild anemia may have no symptoms. As the iron level and blood counts become lower, your child may:

  • Act irritable
  • Become short of breath
  • Crave unusual foods (pica)
  • Eat less food
  • Feel tired or weak all the time
  • Have a sore tongue
  • Have headaches or dizziness

With more severe anemia, your child may have:

  • Blue-tinged or very pale whites of eyes
  • Brittle nails
  • Pale skin

What are the current treatments for Childhood Iron Deficiency Anemia?

Since children only absorb a small amount of the iron they eat, most children need to have 3 mg to 6 mg of iron per day.

Eating healthy foods is the most important way to prevent and treat iron deficiency. Good sources of iron include:

  • Apricots
  • Chicken, turkey, fish, and other meats
  • Dried beans, lentils, and soybeans
  • Eggs
  • Liver
  • Molasses
  • Oatmeal
  • Peanut butter
  • Prune juice
  • Raisins and prunes
  • Spinach, kale and other green leafy vegetables

If a healthy diet does not prevent or treat your child's low iron level and anemia, your provider will likely recommend iron supplements for your child. These are taken by mouth.

DO NOT give your child iron supplements or vitamins with iron without checking with your child's provider. The provider will prescribe the right kind of supplement for your child. Too much iron in children can be toxic.

What is the outlook (prognosis) for Childhood Iron Deficiency Anemia?

With treatment, the outcome is likely to be good. In most cases, the blood counts will return to normal in 2 to 3 months. It is important that the provider finds the cause of your child's iron deficiency.

What are the possible complications for Childhood Iron Deficiency Anemia?

Anemia caused by a low iron level can affect a child's ability to learn in school. A low iron level can cause decreased attention span, reduced alertness, and learning problems in children.

A low iron level can cause the body to absorb too much lead.

How do I prevent Childhood Iron Deficiency Anemia?

Eating a variety of healthy foods is the most important way to prevent and treat iron deficiency.
