Final answer:
Raynaud's disease involves vasospasm of digital arteries and arterioles, leading to reduced blood flow to extremities.
Explanation:
Raynaud's disease is associated with vasospasm of the digital arteries and arterioles. This condition leads to episodes of reduced blood flow to the fingers and toes, causing them to turn white or blue and feel cold and numb.
Vasospasm is believed to be triggered by emotional stress or cold temperature exposure. The treatment includes keeping warm, stress reduction, and, in severe cases, medication to improve blood flow.
Complications of Raynaud's disease may include skin sores or gangrene in severe cases, but most individuals manage the condition well with lifestyle changes and proper care.
