Question
My baby is over 20 days old, and their fingernails have turned purple. Their feet and mouth are normal; what could be the cause?
Answer
Purple fingernails in a baby may be related to cold weather or insufficient blood supply. Given the current weather, the baby’s fingernails turning purple is not too cold. The patient’s condition indicates insufficient blood supply. It is advisable to go to the hospital for relevant examinations and a clear diagnosis as soon as possible. We can only say that there is a possibility of this condition. The nails may not necessarily be purple, but they will definitely become ill. For safety’s sake, it is recommended to check the baby’s blood circulation in the pediatric department and see if there is any sign of hypoxia.
