Fingers turning blue (peripheral cyanosis) is when the hands, fingertips, or feet turn white or blue because they are not getting enough oxygen or blood.
Seek professional care if you experience any of the following symptoms
Generally, Fingers turn blue can be related to:
Tracheal stenosis is an abnormal narrowing of the trachea, also known as the windpipe, that restricts normal breathing.
Tracheomalacia literally translates to floppy airway (trachea) and happens when the tissues of the airway instead of being rigid and stiff, are weak and floppy, causing breathing difficulties. This can be due to intrinsic issues with tissues (cartilage) of the windpipe (trachea) itself or due to something in the chest pushing on the airway such as a blood vessel. As there are highly variable severities and types of tracheomalacia, the symptoms vary greatly as well.
This is a rare inflammatory disease affecting the arms and legs due to blood clots of the small and medium-sized arteries and veins. It is not due to blockage from fats and cholesterols. It tends to happen in younger men who are heavy smokers and can lead to complete loss of blood to fingertips requiring amputation.
Sometimes, Fingers turn blue may be related to these serious diseases:
Acute myocarditis is inflammation of the heart muscle (myocardium). It can affect anyone but is more common in infants and teenagers. It can impact the heart's ability to pump blood effectively and may cause rapid or irregular heart rhythm. It's usually caused by a viral infection, and sometimes by drug reactions or autoimmune disorders.
Your doctor may ask these questions to check for this symptom:

Male, 20s
My experience was great. I was worried, but the symptom checker helped me narrow down what it might be. I feel a little relieved compared to when I first started, and it gives me a starting point for what my symptoms could mean.

Male, 50s
The questions asked and possible causes seemed spot on, putting me at ease for a next-step solution.
(Sep 26, 2024)
Female, 40s
I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
