Answer 2

Blue lips can be a sign of poor circulation or lack of oxygen in the blood. This condition is called cyanosis and can be caused by various medical conditions such as heart or lung problems, or exposure to cold temperatures. If your lips turn blue, it is important to seek medical attention to determine the underlying cause.
