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.

 

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.
