Iron Deficiency Anemia in Children

Anemia refers to a reduction in the blood's capacity to transport oxygen from the lungs to the tissues, resulting in a lack of oxygen in the tissues. This lack of oxygen in the tissues affects the entire body, which is a significant issue, especially for infants and children in their rapid growth phase. Iron deficiency anemia is when the amount of iron in the body falls below normal levels for various reasons. In iron deficiency, anemia occurs because the iron stores are insufficient for blood production. It is the most common blood disorder during infancy and childhood. The prevalence of iron deficiency anemia is quite high in infants and children aged 0-24 months, and this age group is considered the most common period for iron deficiency.

While the iron level is high in the first months after birth, it begins to decrease in the following months. Iron is widely used in the human body, and its deficiency affects all systems, leading to clinical symptoms. This situation can negatively impact not only physical development but also cognitive and psychomotor development.

Symptoms and Diagnostic Methods of Anemia

Iron deficiency anemia may not show significant symptoms in the early stages. However, careful observation by parents is vital for early diagnosis.

• Physical Symptoms:

• Pale skin and mucous membranes: This is one of the most obvious signs of anemia. The skin color of the baby or child becomes pale, especially the insides of the lips and nail beds appear whiter than normal.

• Loss of appetite and slow weight gain: Iron deficiency can lead to loss of appetite and nutritional inadequacy.

• Frequent infections: Iron is necessary for the immune system to function properly. Its deficiency makes the child more vulnerable to diseases.

• Fatigue and weakness: The child may appear constantly tired and weak, even at ages when they should normally be energetic.

• Behavioral and Developmental Symptoms:

• Irritability and fussiness: The child may become more restless and easily irritated due to iron deficiency.

• Attention deficit and learning difficulties: School-aged children may experience attention distractions and focus issues.

• Developmental delays: Iron deficiency can slow down the child's motor and cognitive development.

Diagnosis: After taking the patient history, laboratory tests are performed. A complete blood count showing values below the age-appropriate Hb (hemoglobin) levels in children is considered anemia. Additionally, measuring the ferritin level indicating blood iron and stored iron can definitively diagnose iron deficiency anemia.

Causes: Nutritional and Environmental Factors

Iron deficiency anemia in children is most commonly seen due to inadequate nutrition, low socio-economic status, inflammation, and parasitic diseases.

• Inadequate Nutrition: In the nutrition of infants, breast milk is sufficient for the first 6 months after birth. After that, it is recommended to introduce iron-rich complementary foods in addition to breast milk. It has been observed that those fed with formula and cow's milk instead of breast milk during the first 6 months have a higher incidence of iron deficiency anemia. Iron-fortified formulas, pureed red meat, egg yolk, and legumes are important foods for infants.

• Low Socio-Economic Status: In low-income families, difficulty in accessing iron-rich foods can increase the risk of iron deficiency anemia.

• Infections and Parasites: Chronic infections or intestinal parasites can cause iron deficiency by disrupting iron absorption or leading to blood loss.

Prevention Methods: The Best Treatment is Preventive Medicine

Five key practices are important in preventing iron deficiency anemia. These steps offer a proactive approach to prevent the disease from occurring.

• Determining the Prevalence Rate of Anemia: Identifying the anemia rates in the community helps to detect at-risk groups.

• Nutrition Education: Parents should be educated about the importance of iron-rich foods in their children's diet.

• Prophylactic Iron Supplementation: Prophylactic iron supplementation, accepted worldwide, is the most important protective method. Iron supplementation given to infants should be continued for the duration recommended by the doctor. A study conducted on 6-month-old infants showed that the incidence of iron deficiency anemia decreased from 30% to 2% with prophylactic iron supplementation. The same study found that children receiving prophylactic iron supplementation had improved mental and physical scores by the 13th month. This support can be started after the 4th month and continued until the age of 1.

• Disease Control: Controlling viral, bacterial, and parasitic diseases eliminates issues affecting iron absorption.

• Fortifying Foods with Iron: In some countries, staple foods (such as bread and flour) are fortified with iron to increase the overall iron intake level of the community.

Treatment Methods and Process

When diagnosed with iron deficiency anemia, the treatment process should be initiated immediately.

• Oral Iron Medication: The iron medication used in treatment is usually administered orally. The medication is better tolerated when given as a single dose half an hour before breakfast to children and infants under 24 months. It is important to avoid consuming the medication with dairy products, as they inhibit iron absorption.

• Tips for Medication Use: Iron medication can temporarily change the color of teeth and stool. Administering it with a straw or diluting it can minimize staining of the teeth. The dark green or black color of the stool indicates that the medication has been absorbed, which is a normal sign.

• Treatment Duration: The patient's values return to normal within 2-4 weeks. However, treatment should continue for a few months to fully replenish iron stores. It is critical for parents to continue treatment even after their child starts to look better, as this is essential for complete recovery.

• Injection Treatment: For patients who have absorption issues in the intestines or cannot tolerate oral medication, iron is injected into the buttock. This is a method applied when oral treatment is not possible.

In conclusion, iron deficiency anemia in children is a serious but preventable and treatable health issue. Parents being aware, paying attention to nutrition, regularly using the iron supplements recommended by the doctor, and consulting a specialist without delay when symptoms arise are the most important steps for their children to grow and develop healthily.
