What Is Raynaud's Disease?

Raynaud's disease is a disorder that affects the arteries causing them to narrow as stated by the Mayo Clinic. As the arteries narrow, the blood circulation becomes limited.

As circulation is limited, certain parts of the body such as the toes can become numb and cold. The disease affects more women than men and a person can experience primary or secondary Raynaud's. Primary Raynaud's happens more frequently and the cause of the disease is unknown. The disease is also less severe than secondary types.

Secondary Raynaud's is caused by another medical condition and the symptoms seem more severe. In some cases, the fingers or toes affected can turn blue or white as circulation is hindered according to the National Heart, Lung and Blood Institute.

Most cases of the disease are not life threatening though the symptoms can become bothersome. In severe cases, the disease can cause repeated lack of blood flow which can result in long-term damage.

Treatment for Raynaud's disease can include treating an underlying disorder causing the problem. Avoiding caffeine and nicotine and reducing stress can also help reduce the symptoms. There isn't a cure for the disease, but in severe cases, a calcium channel blocking medication can be used as a treatment option.
