Doctor's answer:

Oral and lip cyanosis is commonly seen in congenital heart disease. In this case, it is necessary to undergo an echocardiogram to rule it out. If the echocardiogram shows no significant issues, further tests are needed to rule out other diseases.
Hello, in this situation, it is essential to visit the neurology department of the hospital for examination. It may have been caused by convulsions or hypoxia at the time, resulting in oral and lip cyanosis.
It is recommended to conduct the main tests, including a head CT or MRI, and an electroencephalogram (EEG). Additionally, an echocardiogram or chest X-ray should be performed to rule out the possibility of congenital heart disease. Only after these examinations can a clear diagnosis be made.
