Question

How does Raynaud Syndrome affects the body?

Like its effect on blood vessels, thanks a lot!

Answer 1

Raynaud's syndrome is a medical condition in which spasm of arteries cause episodes of reduced blood flow.

Explanation:

During an episode of Raynaud's the blood supply in the affected areas is markedly reduced. The skin turns pale and becomes cold and numb. On further depletion of oxygen supply, the skin turns blue. As the episode subsides or the area is warmed, the blood flow returns. The skin turns red and then normal.
This is accompanied by swelling, tingling and a painful 'pins and needles' sensation.

Raynaud's is often caused in response to cold temperatures or stress. Mostly the fingers are affected and some times toes, nose, ears or lips are affected.
