Cold and stress: We do not completely understand the cause of raynaud's, but exposure to cold and emotional stress cause spasm in the blood vessels of the hands and feet. This causes a reduction in blood flow. The lack of oxygen in the area cause the color to change to white, with continued lack of oxygen they turn blue and then red as the spasm resolves and blood flow returns.

Usually cold: Raynauds involves cold or stress induced vasospasm of small vessels in hands and feet. It is really more of an annoyance than a harmful problem. Calcium channel blockers are the most common medication that physicians use to treat the symptoms of raynauds. The main drawback is the side effects from these medicines. Keeping your hands and feet warm remains the best treatment.

Cold and Stress: Doctors don't completely understand the cause of raynaud's attacks, but blood vessels in the hands and feet appear to overreact to cold temperatures or stress. With raynaud's, arteries to your fingers and toes go into vasospasm. Vasospasm narrows your vessels dramatically and temporarily limits blood supply. Secondary raynaud's may be associated with several underlying diseases, usually autoimmune.

Auto-immune: The direct evidence for causal relationship between celiac disease and Raynaud is lacking or we don't know. Celiac disease is an autoimmune disease. Secondary Raynauds is also an autoimmune condition. A person with Raynaud’s is thus more likely to have celiac disease than that in the general population by a poorly defined immune mechanism.

What is raynaud's phenomenon?

Dr. Robert Cuff
Vascular Surgery 24 years experience
Vasoapastic response: Raynaud's phenomenon is an exaggerated vasoapastic response to cold weather and stress. The blood vessels of the extremity normally dilate and constrict with temperature changes. This occurs to an extreme degree in patients with raynauds. They will experience blue or white fingers or toes when exposed to cold temperature or stress. This is self-limiting and rarely causes significant problems.
