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

• Hands and feet turn pale and blue

Generally, Fingers turn blue can be related to:

• Tracheal Stenosis

  Tracheal stenosis is an abnormal narrowing of the trachea, also known as the windpipe, that restricts normal breathing.

• Tracheomalacia

  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.

• Buerger's Disease (Thromboangiitis Obliterans)

  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.

• Diabetic Gangrene
• Pulmonary Arterial Hypertension
• Scleroderma

Sometimes, Fingers turn blue may be related to these serious diseases:

• Acute Myocarditis

  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.

• Aortic Dissection / Aortic Aneurysm Rupture
