What is Raynaud’s?
Raynaud’s, sometimes called a disease, syndrome, or phenomenon is a disorder that affects the blood vessels that carry blood from your heart to different parts of your body.
The disorder is marked by brief episodes of vasospasm, which is a narrowing of the blood vessels in the extremities, most commonly the fingers and toes, but it can involve anybody’s extremity.
As the blood vessels constrict, the affected area may turn white, and possibly blue or purple from the lack of oxygen to the digits. As the patient becomes warm or calm again, the blood rushes back quickly turning the affected area a red or pinkish color.
There are two main types of Raynaud’s—primary and secondary.
In primary Raynaud’s the cause isn’t known. Primary Raynaud’s is more common (90% of sufferers) and symptoms tend to be less severe than those experienced by those with the secondary form of Raynaud’s.
Secondary Raynaud’s can be caused by an underlying disease, condition, or other factor, including such autoimmune diseases as scleroderma, lupus and rheumatoid arthritis. Raynaud’s can be the first sign of one of these more serious autoimmune disorders. As attacks can be more frequent and severe for these patients, painful digital ulcers may develop and, if not treated properly, can result in serious long-term damage to their blood vessels.
The secondary form can also be caused by trauma, excessive smoking, vascular issues, exposure to certain drugs (chemo), chemicals or toxins, and occupational triggers involving repeated pressure to the extremities from the use of vibrating tools and equipment.
While there is no definitive test to detect the primary form of Raynaud’s, there are lab tests to determine if a patient’s Raynaud’s is the more serious secondary form.
