What is the reason why my lips are always purple?

Patient's question:

The child just born, I don't know what's going on, there are always red spots on their body, and they are spitting up milk. Please ask what's wrong with the lips always turning purple

Doctor's answer:

Hello, the baby's lips have recently turned purple, which may be caused by factors such as ischemia, hypoxia, or cold. If there is a mild heart disease, it may not be possible to hear a murmur during auscultation. If the cyanosis persists, it is best to have the baby undergo an echocardiogram to check for any heart disease or other conditions. Wishing you good health.
The child is threatened by neonatal diseases, so parents must take the child to seek medical treatment immediately to avoid blindly using medication to alleviate symptoms. For parents, it is essential to provide the child with enough care and attention and to do everything possible to help the child receive timely medical treatment for the disease.
