Question

Quizplus · Accepted Answer

Raynaud disease is a condition that affects the blood supply to certain parts of the body, usually the fingers and toes. It presents with episodic attacks of vasoconstriction, causing the affected areas to turn white and cold (pallor phase), followed by blueness (cyanosis phase), and then redness (hyperemia phase) as the blood flow returns. This process is triggered by exposure to cold, emotional stress, or other factors that cause narrowing of blood vessels. The cause of Raynaud disease is unknown, hence it is considered an idiopathic disease.
