General Information About Raynaud's Syndrome
Disease Details and Frequently Asked Questions
It is the condition where the capillary arteries supplying the fingers and sometimes the toes experience intense spasms when the weather turns cold or the person undergoes significant stress, completely stopping blood flow to the digits within seconds.
Because the blood vessels constrict during an attack, the fingers turn pale yellow/stark white as if drained of blood. Next, as the trapped blood runs out of oxygen, they take on a near-black blue/purple color. When they warm up and the vessels suddenly dilate, blood rushes back in and the fingers turn bright red.
Primary Raynaud's: Common in young women, it has no underlying disease, occurs on its own, and is harmless.
Secondary Raynaud's: It emerges as an early warning sign of severe autoimmune rheumatic diseases like Scleroderma or Lupus, and can cause ulcers/sores.
Going outside in the winter, being highly exposed to air conditioning, or even holding a frozen bag from the freezer with bare hands is enough to instantly trigger a vascular spasm.
By examining the microscopic blood vessels at the base of the nails with a magnifying tool (Capillaroscopy), it is definitively distinguished whether the disease is a simple Raynaud's phenomenon or a precursor to a rheumatic disease.
The primary treatment is the constant use of gloves and 100% avoidance of the cold. Smoking, which constricts blood vessels, and stressful environments must be avoided. If the symptoms are disrupting daily life, blood pressure medications that relax blood vessel walls (Calcium channel blockers) are prescribed.
