Anemia caused by low iron - 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.
Anemia - iron deficiency - children
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:
Iron deficiency in children can also be related to lead poisoning.
Mild anemia may have no symptoms. As the iron level and blood counts become lower, your child may:
With more severe anemia, your child may have:
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.
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:
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.
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.
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.
Eating a variety of healthy foods is the most important way to prevent and treat iron deficiency.
