Raynaud's syndrome, also called Raynaud's disease, strikes when exposed to cold, dampness, or emotional stress. This typically benign condition disrupts daily life, especially in winter, by impairing blood flow to extremities like fingers, toes, feet, and nose. It predominantly affects women.
Distinguishing between Raynaud's disease and syndrome is key: the primary form, disease, often emerges between ages 15 and 25. The secondary form, syndrome, is rarer and more serious, usually appearing around age 40. Either can occur independently, though a disease diagnosis warrants monitoring, as symptoms may signal underlying issues.
First described in 1862, Raynaud's involves episodic circulatory disruptions. Attacks hit suddenly: affected areas turn white, cold, numb, or painful. Primarily targeting fingers and toes, it can also involve the nose, lips, and ears.
Exact causes remain unclear, but frostbite, hand injuries, manual labor, arthritis, carpal tunnel syndrome, and genetics heighten risk.
Unlike acrocyanosis—a constant, benign cold sensitivity—Raynaud's attacks are paroxysmal, striking unpredictably. They unfold in three phases: pallor (white), cyanosis (blue), and reperfusion (red with tingling and pain).
Diagnosis involves vascular pulse checks and nailfold capillaroscopy to confirm Raynaud's or rule out conditions like arteritis.
Primary defense is cold protection: layer silk inner gloves under fleece outer ones for hands; thick wool socks for feet. Cover head and neck to retain body heat.
No cure exists, but severe cases may benefit from prescribed calcium channel blockers under medical supervision.
