Children’s uneven nails may be caused by anemia, lack of trace elements, trauma and other reasons. 1. Anemia: If children are in the state of anemia, it can lead to insufficient blood supply and oxygen supply to the nails, and the phenomenon of uneven nails can occur. 2. Lack of micronutrients: If children lack zinc and other micronutrients because they are picky eaters, they may suffer from malnutrition and have uneven nails. 3. Trauma: If the child’s fingers are squeezed and other traumatic injuries, nail deformation may occur. Parents are advised to take their children to regular hospitals for consultation to clarify the cause, and if treatment is needed, standardized treatment should be carried out under the guidance of doctors to avoid delaying the condition.
