Symptoms Of Raynaud's Disease

White Or Blue Skin

The color changes that happen with Raynaud's disease often cause white or blue skin. White or blue skin happens through the same mechanisms previously described. The arterial blood flow is cut off, and the lack of oxygenated blood and warmth causes the color to change. Normally, the skin will turn white first because of the loss of blood flow. This is referred to as pallor. The skin will begin to take on the blue hue, called cyanosis, as the blood left in the areas loses the rest of its oxygen. The color should turn very red and then normalize when the blood flow returns to the affected areas. When the color takes a long time to reverse to normal, there may be an underlying cause of the Raynaud's disease.
