Iron deficiency anemia

Teens grow and develop rapidly and need iron in their diet to develop normally. If a teen does not consume enough iron, there is a risk of developing iron deficiency. Iron deficiency can cause anemia, a condition that can delay a teen's mental, motor, and behavioral development and create problems that last long after the iron level is raised to a healthy level. Poor motor skills, behavior problems at home and school, and poor performance in school can be the long-term consequences of not receiving enough iron as a child.

Iron deficiency may also be due to a severe blood loss, a genetic disorder, or something interfering with the body's ability to absorb iron, such as a medication the teen is taking or a chronic illness (e.g., celiac disease).

The American Academy of Pediatrics (AAP) recommends teens be screened with a hemoglobin and hematocrit test if they have risk factors for iron deficiency or iron deficiency anemia.

Risk factors for iron deficiency anemia in teens may include:

  • Households with a low income or living in poverty
  • Poor or restricted diet that doesn't provide enough iron
  • Teen girls who begin menstruating can be at risk if they don't consume enough iron
  • History of:
    • Medications that interfere with iron absorption
    • Extensive blood loss
    • Exposure to lead
