Patient's question:
The baby in my brother's family is now about three and a half months old. Due to insufficient breast milk, they are currently drinking formula. However, recently, the baby has been choking while drinking milk. So, I would like to consult about why the child is choking.Doctor's answer:
Infant asphyxia is closely related to vitamin A deficiency, and supplementing with vitamin A can produce good effects. Researchers believe that vitamin A plays an important role in maintaining the normal structure and health of skin and mucous membrane epithelial cells. When infants lack vitamin A, asphyxia occurs because the epithelial cells of the upper pharynx, located in the upper and anterior parts of the larynx, atrophy and keratinize, leading to insufficient closure of the pharynx during swallowing, causing the trachea to be obstructed.
