Anemia caused by low iron - children
Anemia - iron deficiency - children
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, so a lack of iron in the body may lead to anemia. The medical name of this problem is iron deficiency anemia.
Causes
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 .

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

Exams and Tests
The health care provider will perform a physical exam.
Blood tests that measure iron level in the body include:

A measurement called iron saturation (serum iron/TIBC) often can show whether the child has enough iron in the body.
Treatment
Since children only absorb a small amount of the iron they eat, most children need to have 8 to 10 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 greens
If a healthy diet does not prevent or treat your child's low iron level and anemia, the doctor 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 doctor. The doctor will prescribe the right kind of supplement for your child. If your child takes too much iron, it can cause poisoning.
Outlook (Prognosis)
With treatment, the outcome is likely to be good. In most cases, the blood counts will return to normal in 2 months. It is important that the doctor find the cause of your child's iron deficiency.
Possible Complications
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.
Prevention
Eating a variety of healthy foods is the most important way to prevent and treat iron deficiency.

Formed elements of blood - illustration
Blood transports oxygen and nutrients to body tissues and returns waste and carbon dioxide. Blood distributes nearly everything that is carried from one area in the body to another place within the body. For example, blood transports hormones from endocrine organs to their target organs and tissues. Blood helps maintain body temperature and normal pH levels in body tissues. The protective functions of blood include clot formation and the prevention of infection.

Hemoglobin - illustration
Hemoglobin is the most important component of red blood cells. It is composed of a protein called heme, which binds oxygen. In the lungs, oxygen is exchanged for carbon dioxide. Abnormalities of an individual's hemoglobin value can indicate defects in the normal balance between red blood cell production and destruction. Both low and high values can indicate disease states.
