Dr. Wang Xiaoyan
Black or purple lips may be caused by physiological factors, chronic bronchitis, congenital heart disease, or other reasons:
1. Physiological factors: Long-term smoking or working outdoors for extended periods, leading to prolonged ultraviolet exposure on the lips, may cause the lips to darken or turn purple.
2. Chronic bronchitis: In elderly individuals with weakened immunity or due to viral infections, chronic bronchitis may develop, which could lead to black or purple lips.
3. Congenital heart disease: Darkened lips may also be caused by congenital heart disease, which could result from medication use during early pregnancy or a history of adverse reproductive events.
