You may have noticed that your lips turn purple or blue in the cold, or you may have seen a baby, an elderly person or someone else with bluish or purplish lips. In many cases, this type is caused by cyanosis, which is a discoloration of a part of the body resulting from a lack of oxygen in the blood.
Cyanosis describes the symptom that happens when a personâs skin, lips, or fingernail beds turn from the personâs natural color to a blue or bluish color. The color might also look grayish or dark purple. âCentral cyanosisâ is blueness that mainly affects the lips, tongue, and mouth. âPeripheral cyanosisâ is blueness in the skin of the arms, legs, feet, hands, fingers and fingernail beds. Both of these kinds of cyanosis can be caused by COPD or by complications of COPD.
