Question
My child has been biting their nails unintentionally for three years. They have undergone treatment but it was ineffective. I hope to understand how to help my child stop biting their nails or if they need to supplement specific elements.
Answer
Based on your description, the habit of nail-biting may be related to a deficiency in trace elements. It is recommended that you take your child to the hospital for trace element testing and follow the doctor’s advice for symptomatic treatment. Additionally, it is suggested to eat more fresh vegetables and fruits for symptomatic treatment. I hope my explanation is helpful.
