What medical condition causes blue skin?

People whose blood is low in oxygen tend to have a bluish color to their skin. This condition is called cyanosis. Depending on the cause, cyanosis may develop suddenly, along with shortness of breath and other symptoms. Cyanosis that is caused by long-term heart or lung problems may develop slowly.

What types of illnesses can cyanosis indicate?

Cyanosis shows up as the levels of deoxygenated blood rises in the small blood vessels of the fingers and toes. This may be seen in heart failure, shock (sluggish or slowing of blood circulation with severe loss of blood pressure), exposure to cold temperatures and diseases of blood circulation.

Are there humans with blue skin?

Yes, it turns out, and a family living in Appalachia had the condition for generations. In their case, blue skin was caused by a rare genetic disease called methemoglobinemia. Methemoglobinemia is a blood disorder in which an abnormally high amount of methemoglobin — a form of hemoglobin — is produced.

What is the most common cause of cyanosis?

Low cardiac output, venous stasis, and exposure to extreme cold causing vasoconstrictions are some of the conditions that can cause peripheral cyanosis. Furthermore, cyanosis can be caused by the presence of abnormal hemoglobin. Hemoglobin is the major carrier of oxygen in the blood.

Is methemoglobinemia caused by inbreeding?

The genetic form of methemoglobinemia is caused by one of several genetic defects, according to Tefferi. The Fugates probably had a deficiency in the enzyme called cytochrome-b5 methemoglobin reductase, which is responsible for recessive congenital methemoglobinemia.

What are the signs and symptoms of cyanosis?

Cyanosis is characterized by bluish discoloration of skin and mucous membranes. Cyanosis is usually a sign of an underlying condition rather than being a disease in itself. The most common symptoms of the condition are bluish discoloration of the lips, fingers, and toes.
