Question
How do you handle the persistent respiratory infections in a three-year-old child?
Answer
Based on the description, frequent respiratory infections in children may be related to deficiencies in trace elements and vitamins, particularly vitamin A and zinc. Deficiencies in these nutrients can lead to a decrease in mucosal barrier function and a weakened immune system. Therefore, it is recommended to supplement with vitamin A and glycine zinc. This is the suggested approach to the issue, and I hope it is helpful to you. Wishing you health.
