My Baby Has G6PD Deficiency — What Do I Need to Avoid?

Editorially reviewed | Sources: NIH, AAP, WHO|Updated June 2026

The short answer

G6PD (glucose-6-phosphate dehydrogenase) deficiency is the most common enzyme deficiency worldwide, affecting approximately 400 million people. It is an X-linked condition, meaning it primarily affects males. G6PD helps protect red blood cells from damage. When triggered by certain foods, medications, infections, or chemicals, a baby with G6PD deficiency can have a hemolytic episode — their red blood cells break down faster than the body can replace them, causing anemia and jaundice. The key to managing G6PD deficiency is knowing and avoiding triggers. Between episodes, children with G6PD deficiency are completely healthy.

Thousands of parents search for this exact thing. You are not alone.

By Age

What to expect by age

0-1 month (newborn period)

G6PD deficiency can cause severe neonatal jaundice, sometimes within the first 24 hours of life. This jaundice can be more severe and prolonged than typical newborn jaundice. If G6PD deficiency runs in your family, alert your pediatrician so your baby can be monitored closely. Some newborn screening panels include G6PD. Exposure to naphthalene (mothballs), certain antibiotics, or other triggers should be strictly avoided.

1-6 months

During this period, common triggers to avoid include: naphthalene (mothballs, some air fresheners), certain medications (sulfonamide antibiotics, rasburicase, dapsone), and henna. If you are breastfeeding, eating fava beans yourself is generally considered safe for your baby, but check with your pediatrician. Your baby should have a medical ID or note in their chart indicating G6PD deficiency so that unsafe medications are not given during illness.

6-12 months (starting solids)

When introducing solid foods, fava beans (broad beans) are the most well-known food trigger and should be avoided. Other legumes are generally safe. If your baby gets sick with an infection, monitor for signs of hemolysis — sudden pallor, dark urine (tea or cola colored), yellowing of the skin or eyes, and increased fussiness or lethargy. Infections themselves can trigger hemolytic episodes in G6PD-deficient babies.

1 year+

As your child grows, teaching them about their condition becomes important. The list of medications to avoid should be shared with all healthcare providers, schools, and caregivers. Most children with G6PD deficiency live completely normal lives with the simple precaution of avoiding known triggers. Hemolytic episodes, when they occur, are usually self-limited once the trigger is removed, though severe cases may require blood transfusion.

What Should You Do?

When to take action

Probably normal when...
  • Your baby has G6PD deficiency but is healthy and thriving between any episodes
  • Your baby had neonatal jaundice related to G6PD that resolved with phototherapy
  • You are successfully managing the condition by avoiding known triggers
Mention at your next visit when...
  • Your baby is starting a new medication and you want to confirm it is safe with G6PD deficiency
  • Your baby seems more yellow than usual or their whites of their eyes look yellow
  • You are unsure about which foods and household products to avoid
  • A family member has G6PD deficiency and you want your baby tested
Act now when...
  • Your baby's urine is dark (tea or cola colored) — this indicates red blood cell breakdown and requires urgent medical evaluation
  • Your baby suddenly becomes pale, lethargic, and is breathing rapidly — this may indicate severe anemia from a hemolytic episode. Go to the emergency room
  • Your baby has severe jaundice (deep yellow or orange skin, yellow eyes) — this needs immediate evaluation, especially in the first two weeks of life

Trust your instincts. If something feels wrong, reach out to your pediatrician.

Worrying about your baby means you care. That is a good thing.

How Dangerous Is My Baby's Jaundice? (Kernicterus Prevention)

Jaundice (yellowing of the skin from bilirubin) is extremely common in newborns — about 60% of term and 80% of preterm babies develop it. Most jaundice is harmless and resolves with or without phototherapy. However, very high bilirubin levels can cross into the brain and cause permanent damage (kernicterus), including cerebral palsy, hearing loss, and intellectual disability. Kernicterus is almost entirely preventable with appropriate monitoring and treatment. The key is ensuring bilirubin levels are checked per guidelines and treated promptly when elevated.

My Baby's Head Shape Looks Abnormal

Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.

Achondroplasia (Dwarfism) in Babies

Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.

Adenoid Hypertrophy and Breathing

Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.

How to Advocate for Your Child's Needs

You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.

Air Quality and Baby Health

Babies and young children are more vulnerable to air pollution than adults because they breathe faster, their lungs are still developing, and they spend more time close to the ground where some pollutants concentrate. The EPA recommends keeping babies indoors when the Air Quality Index (AQI) exceeds 100 (orange level). During wildfire smoke events, keep windows closed, use air purifiers with HEPA filters, and monitor your child for coughing, wheezing, or difficulty breathing. Long-term exposure to air pollution can affect lung development.
