What is the reason for the black and purple mouth

The lips are the most sensitive and soft part of the face, and there are more blood vessels on the lips. The normal blood flow will make the lips look full and red, which is a testimony to the health of the body. But there will also be purple lips, black, white and so on. What exactly is the cause of lip color change?

Cold weather and freezing

In cold weather, it is easier to have purple and black lips may be caused by the cold weather affecting the blood. When the skin is frozen, it causes the nerve center to immediately command the skin blood vessels to contract in order to reduce the heat dissipation in the body. Once frozen for a longer period of time, the nerve sensation becomes abnormal and affects the expansion of blood vessels, resulting in the slowing down of blood flow and the accumulation of a lot of red protein of reduced blood in the lip area, resulting in the lips turning blue-purple.

Physical disease

If the lips are dark and hyperpigmentation is found at the edge of the mouth and lips can be considered because of chronic hyperalgesia and other causes.

Purple lips

The cause of purple lips may be due to the body suffering from chronic obstructive pulmonary disease emphysema and other conditions that lead to a decrease in the oxygen content of the blood. In addition, patients with congenital heart disease may also have purple lips.
