Raynaud's+Disease



So what actually happens? McKenna: With Raynauds, there is a lack of blood flow within the vessel which results in the fingers becoming white, then the vessel dilate in order for blood to get through the vessel which results in the fingers turning blue, and finally the fingers turn red as a result of blood flow returning to the vessels.

There are two types of Raynaud's: Primary and Secondary Primary: McKenna: Primary Raynaud's is without an underlying disease that is causing this to occur. The arteries do not have any obstruction done to them and have normal blood flow to the fingers at rest.

Secondary: McKenna: Secondary Raynaud's is due to an underlying disease. This may include sclerodoma or an autoimmune disease.

Causes of secondary include:

McKenna: The causes of secondary may include autoimmune disease. connective tissue disease, lupus, rheumatoid arthritis, or carpal tunnel syndrome.

Madeline: This website provides a really clear description of what Raynaud's is, how they tend to treat the disease, and what can cause it. I thought it might be helpful so I attached the link. http://www.mayoclinic.com/health/raynauds-disease/DS00433
