Diagnosis of Primary vs Secondary
|Raynaud's Secondary to Scleroderma
Raynaud's Secondary to Other Diseases
When Raynaud's appears by itself, without any other medical condition, it is called Primary Raynaud's, or Raynaud's Disease. More than 80% of people with Raynaud's have it by itself, not caused by any serious underlying illness. In primary Raynaud's, the blood vessels return to normal afterwards. (Also see What is Raynaud's?)
When Raynaud's appears along with autoimmune diseases such as scleroderma, systemic lupus erythematosus, or rheumatoid arthritis, it is called Secondary Raynaud's, or Raynaud's Phenomenon. (Also see What is Scleroderma?, Lupus, and Rheumatoid Arthritis)
Raynaud's occurs in about 10% of the general population, but only about 20% of people with Raynaud's have an underlying illness.
