Breastfeeding Guidelines for Infants with G6PD Deficiency

Introduction to G6PD Deficiency and Breastfeeding

The American Academy of Pediatrics (AAP) strongly supports breastfeeding for all infants, including those with G6PD deficiency, as it provides numerous benefits such as reducing the risk of infections, decreasing the risk of sudden infant death syndrome (SIDS), and providing optimal nutrition for infant development 1
Breastfeeding contains antibodies and protective factors that support immune function in infants with G6PD deficiency 1

The AAP recommends breastfeeding as it reduces the risk of infections, including respiratory infections and otitis media, in infants with G6PD deficiency 1
Breastfeeding decreases the risk of sudden infant death syndrome (SIDS) by 40-64% depending on duration in infants with G6PD deficiency 1
The AAP lists only a few absolute contraindications to breastfeeding, and G6PD deficiency is not listed as a contraindication 1

G6PD deficiency is a major risk factor for severe hyperbilirubinemia in newborns, and regular monitoring of bilirubin levels is essential, especially in the neonatal period 2, 3
Parents should be educated about signs of jaundice and hemolysis, such as pallor, yellowing of skin/eyes, and dark urine, and the importance of prompt medical attention if jaundice develops 2, 3
The AAP recommends plotting total serum bilirubin (TSB) levels on hour-specific nomograms and intervening at lower TSB levels for G6PD-deficient infants 2
Certain medications, including dapsone 4 and methylene blue 3, should be avoided in infants with G6PD deficiency due to the risk of triggering oxidative stress 3, 4

The AAP recommends initiating breastfeeding as soon as possible after birth and continuing breastfeeding as the primary nutrition source for at least 6 months for infants with G6PD deficiency 1
Infants with G6PD deficiency should be provided a complete multivitamin with minerals due to dietary restrictions, as recommended by the American College of Medical Genetics and Genomics 5
Calcium with vitamin D supplements should be considered if not using calcium-fortified soy milk, as vitamin D deficiency is common in restricted diets, affecting 61.5% of subjects 5
Soy-based, sugar-free formula is an appropriate feeding option, which should be fed on demand every 2-3 hours in infancy, as recommended by the American College of Medical Genetics and Genomics 5
Solid foods should be introduced at a normal timeline (4-6 months), starting with infant cereals, followed by vegetables and then meat, while avoiding fruits, juices, and other foods containing sucrose, fructose, and lactose 5
Overnight gastric feedings may be necessary as the infant grows to prevent hypoglycemia, and continuous monitoring of blood glucose levels is important to maintain levels ≥70 mg/dl 5

Vitamin D deficiency is common in infants with G6PD deficiency, with a prevalence of 61.5%, highlighting the need for supplementation 5
Caregivers should be educated about foods and medications to avoid, including certain medications and foods that can trigger oxidative stress 3, 4
