Reasons for Dark Circles Under a Child's Eyes

Congestion

• According to aboutkidshealth.com, the most common cause of dark circles under the eyes is congestion of the nose. When the nose is blocked, the veins around the eyes become bluer and darker creating the raccoon eye look. The dark circles should dissipate as the child's congestion clears.

Allergies

• Another cause of dark circles under the eyes is allergies. Allergies can congest the nose, cause dry itchy eyes and cause the nasal passages to run. According to kidsgrowth.com, children as young as 2 years can suffer from allergies. If a child's "raccoon eyes" are thought to be due to allergies, a doctor can do further testing.

Sleep Issues

• Lack of sleep or an irregular sleep pattern can be another cause. Help the child to get a good night's sleep by darkening their room, creating a quiet soothing sleep environment, or talk to a doctor for help.

Iron Deficiency

• According to kidsgrowth.com, nutritional issues, such as iron deficiency (anemia) could also cause dark circles under the eyes. Some children are picky eaters and may not be getting enough iron in their diets. A physician can screen a child for iron deficiency.

Mouth Breathing

• Frequent mouth breathing can also cause these dark circles. According to Parents.com, mouth breathing can be due to enlarged adenoids. A chronic sinus infection or recurrent colds can cause children to breath through the mouth more than usual.
