Raynaud’s Disease
Raynaud’s Disease is a disorder that affects the hands and feet. It is caused by contraction of the smooth muscles controlling the small arteries supplying circulation into the hands and feet. This contraction, called a vasospasm, makes the arteries so small that they restrict blood flow. Exposure to cold temperature can often bring on a vasospasm. A color change from white to blue to red is common.
Raynaud’s Disease has no known cause and is most common in young women. Staying warm and regular exercise to maintain healthy blood circulation throughout the body can help offset the disease.
