Iron Deficiency in Children: A Nigerian Guide

Q: How long until iron treatment works?

Haemoglobin starts rising within 2–4 weeks of starting iron treatment. Normal haemoglobin is usually restored in 6–8 weeks, but treatment should continue for 3 months beyond normalisation.

Q: Is it safe to give iron to a child who doesn't have anaemia?

If ferritin is low (iron-depleted stores), supplementation is appropriate. However, do not give iron without a medical assessment — excess iron can be toxic.

Q: What foods contain the most iron?

Liver and kidney (highest), red meat, dark leafy vegetables (bitter leaf, ugwu), beans, lentils, crayfish, and iron-fortified cereals. Iron from meat (haem iron) is absorbed 3× more efficiently than plant iron.

Q: Does malaria cause iron deficiency?

Yes — malaria destroys red blood cells, depleting iron. Repeated malaria episodes are a major driver of chronic iron deficiency in Nigerian children. Prevent malaria with bed nets and early treatment.

Q: Can my child take iron with milk?

Calcium in milk reduces iron absorption. Avoid giving iron syrup with milk or dairy products. Give iron with water or vitamin C-rich juice between meals for best absorption.

Preventing and treating the most common nutritional deficiency in Nigerian children

Iron deficiency is the most common nutritional deficiency in Nigerian children, affecting an estimated 70–75% of children under 5 years. Iron is essential for brain development, immunity, and energy production. Deficiency — even without anaemia — impairs cognitive development, school performance, and immune function. The peak risk period is 6–24 months when rapid growth outstrips iron stores, and the diet often transitions to low-iron weaning foods.

Signs and Symptoms

✓ Pallor of the conjunctiva (inside of lower eyelids), palms, and gums

✓ Fatigue, weakness, reduced activity and play

✓ Poor appetite and slow weight gain

✓ Frequent infections and slow recovery from illness

✓ Irritability, poor concentration, developmental delay

✓ Pica: unusual cravings for soil, chalk, or ice (pagophagia) — classic sign of iron deficiency

✓ Rapid heartbeat and breathlessness on exertion (when anaemia is severe)

Risk Factors

Exclusive pap/akamu feeding from 6 months — very low iron content
Cow's milk as primary drink before 12 months — interferes with iron absorption
Low intake of meat, fish, and iron-rich vegetables
Frequent infections and malaria — deplete iron stores
Prematurity: lower iron stores at birth
Helminth (worm) infestation: hookworm causes chronic intestinal blood loss
Tea or coffee consumption near meals — tannins block iron absorption

When to Seek Help

See a health workerAny child who looks pale, is tired and listless, has poor appetite, or shows developmental delays — get a blood test

UrgentChild is breathless at rest, has a rapid heartbeat, or looks very pale — severe anaemia may need urgent assessment and possible blood transfusion

Developmental concernChild with confirmed iron deficiency and any developmental delay — early iron treatment and developmental support improves outcomes

Tests & Diagnosis

🧪 Full blood count (FBC)

Haemoglobin <11g/dL in children under 5 indicates anaemia; low MCV (microcytic) and MCH (hypochromic) suggest iron deficiency

🧪 Serum ferritin

Best marker of iron stores; <12 μg/L indicates iron deficiency even before anaemia develops — can catch deficiency early

🧪 Peripheral blood film

Shows microcytic, hypochromic red cells (pencil cells) in iron deficiency

🧪 Serum iron and TIBC

Low serum iron with high total iron binding capacity (TIBC) = iron deficiency; distinguishes from anaemia of chronic disease

🧪 Stool microscopy

To check for hookworm or other helminths causing blood loss

Treatment Options

Oral iron supplementation

Iron syrup (ferrous sulphate or ferrous gluconate): 3–6 mg/kg of elemental iron per day in 2 divided doses; give between meals; expect black/green stools — normal

Duration of treatment

Continue iron supplementation for 3 months after haemoglobin normalises to replenish stores

Vitamin C to enhance absorption

Give iron with orange juice, tomato juice, or vitamin C tablet — enhances absorption by up to 3×

Dietary iron improvement

Introduce iron-rich foods: red meat, liver, kidney, beans, dark green leafy vegetables; fortified cereal; crayfish; dried fish

Treat underlying causes

Deworm with albendazole or mebendazole every 6 months from 12 months of age (mass deworming); treat malaria

Iron-fortified foods

Use iron-fortified maize flour, ready-made complementary foods (e.g. Nutrend, Golden Morn with iron) when available
