Question
What are the causes of blue lips in newborns?
Answer
Blue lips in newborns may be due to exposure to cold. If this is ruled out, further examination is needed to exclude possible heart diseases or other medical issues. A preliminary consideration might be cyanosis, and it is recommended to undergo a detailed examination to determine the cause, including echocardiography, chest CT scan, and routine blood tests, to treat the specific cause. Specific treatment recommendations should follow the doctor’s guidance.
