Oxygen deprivation does not usually occur in newborns who are underfed, but it may occur if the baby is chronically underfed, resulting in malnutrition, or if he or she cries more than once due to underfeeding. Hypoxia is usually associated with intrauterine distress, birth injury, congenital heart disease, intrauterine infections, and adverse reactions such as difficulty breathing and purple lips. However, if a newborn is chronically underfed, resulting in severe malnutrition, or if he or she cries excessively due to underfeeding, hypoxia may occur. Newborns as a result of the newborn soon, so parents need to take care of, abnormalities need to go to the hospital in a timely manner to carry out relevant examinations, clear the cause of the disease and then actively treat the symptoms.
