When your baby exhibits dark blue or purplish circles under her eyes, you may wonder if this is a normal occurrence or a sign of something more serious. Because dark circles under your baby's eyes could be a sign of an underlying condition such as allergies, it's important to observe to observe her for any accompanying symptoms to help make a definitive diagnosis.
Congestion
Nasal congestion is one of the chief reasons why a baby may have dark circles under her eyes, according to BabyCenter.com. When the nose becomes blocked, the veins that drain from the eyes to the nose can become blocked, according to AboutKidsHealth, a service of The Hospital for Sick Children in Toronto. This results in the the veins swelling, which brings them closer to the skin and makes the area underneath your baby's eyes appear darker in color.
Blockages
Dark circles also can be indicative of chronic sinus infections, a long-lasting cold or nasal blockage due to enlarged adenoids, according to AboutKidsHealth. If you observe your child breathing through her mouth, this could mean your child's adenoids are enlarged.
Treatments
Treating the underlying conditions that may be causing your baby's dark under-eye circles can help to eliminate their appearance, according to Parents.com. If it's determined your child has allergies, ask your physician what allergy treatments may be appropriate for your child or if a nasal spray would work. You should not give your baby adult doses of allergy medicines--instead, ask your doctor what the appropriate medication and dose should be.
Expert Insight
Barton D. Schmitt, M.D., director of general consultative services at the Children's Hospital of Denver and author of "Your Child's Health," says dark circles are rarely cause for concern, according to Parents.com. They are neither a sign of poor health or loss in sleep, Dr. Schmitt says. He also says that children who possess a very fair complexion may have more noticeable under-eye circles.
