Raynaud’s phenomenon is a disorder that affects blood vessels, mostly in the fingers and toes. It causes the blood vessels to narrow when you are:
People of all ages can have Raynaud’s phenomenon. Raynaud’s phenomenon may run in families, but more research is needed.
The primary form is the most common. It most often starts between age 15 and 25. It is most common in:
The secondary form tends to start after age 35 to 40. It is most common in people with connective tissue diseases, such as scleroderma, Sjögren’s syndrome, and lupus. Other possible causes include:
People with certain jobs may be more likely to get the secondary form:
The body saves heat when it is cold by slowing the supply of blood to the skin. It does this by making blood vessels more narrow.
With Raynaud’s phenomenon, the body’s reaction to cold or stress is stronger than normal. It makes blood vessels narrow faster and tighter than normal. When this happens, it is called an “attack.”
During an attack, the fingers and toes can change colors. They may go from white to blue to red. They may also feel cold and numb from lack of blood flow. As the attack ends and blood flow returns, fingers or toes can throb and tingle. After the cold parts of the body warm up, normal blood flow returns in about 15 minutes.
Primary Raynaud’s phenomenon is often so mild a person never seeks treatment.
Secondary Raynaud’s phenomenon is more serious and complex. It is caused when diseases reduce blood flow to fingers and toes.
It is fairly easy to diagnose Raynaud’s phenomenon. But it is harder to find out whether a person has the primary or the secondary form of the disorder.
Doctors will diagnose which form it is using a complete history, an exam, and tests. Tests may include:
Treatment aims to:
Primary Raynaud’s phenomenon does not lead to tissue damage, so nondrug treatment is used first. Treatment with medicine is more common with secondary Raynaud’s.
Severe cases of Raynaud’s can lead to sores or gangrene (tissue death) in the fingers and toes. These cases can be painful and hard to treat. In severe cases that cause skin ulcers and serious tissue damage, surgery may be used.
To reduce how long and severe attacks are:
See a doctor if:
People with secondary Raynaud’s phenomenon are often treated with:
If blood flow doesn’t return and finger loss is a risk, you will need other medicines.
Pregnant woman should not take these medicines. Sometimes Raynaud’s phenomenon gets better or goes away when a woman is pregnant.
