Hello,
There are various possibilities for blue lips.Lips can turn blue in cold weather or when there is inadequate oxygen circulation,anemia,iron deficiency,circulatory disorders and in smokers. It can also occur in heart and lung disorders.
I feel that a physician’s evaluation and investigations to rule out the above conditions are needed at the moment.Pls get it done. .Treatment depends on the same.
