Question
Our three-month-old baby is experiencing coughing up milk while drinking formula. What could be the reasons for this?
Answer
Coughing up milk in babies is closely related to a deficiency in vitamin A, and supplementing with vitamin A can produce good results. Research indicates that vitamin A plays a crucial role in maintaining the normal structure and health of the epithelial cells of the skin and mucous membranes. When a baby has insufficient vitamin A in their body, the epithelial cells in the upper throat may atrophy and keratinize, leading to incomplete closure of the trachea during swallowing, which in turn causes coughing up milk.
