Question
What causes newborns to have purple lips?
Answer
Purple lips in newborns can be due to catching a cold, but they may also be caused by diseases such as hypoxia. If the possibility of catching a cold is ruled out, it is recommended to take the baby to the hospital for further examination to exclude heart-related diseases. Procedures such as echocardiography, chest CT, and blood tests can be conducted to determine the cause, which may include congenital heart disease, lung disease, or blood diseases, and appropriate treatment can then be administered. The above information is for reference only, and specific guidance should be followed according to the doctor’s advice.
