Many concerned parents have questions and worries about their children’s fingernails developing white spots. Although there is no clear explanation mechanism for white spots on nails in medical terms, clinical observations have shown that some children lacking calcium and zinc may experience this condition. It is recommended that parents take their children to the hospital for a trace element test to determine the cause and receive appropriate treatment. At the same time, pay attention to a balanced diet for your child, ensuring adequate intake of calcium and zinc, which can help prevent and improve this situation.
