What Is Raynaud's Syndrome?
3. What Causes Raynaud’s?
The causes of Raynaud’s are not always known. Blood disorders that lead to a thickening of the blood are potential factors that lead to the disease. The excess platelets or blood cells associated with some blood disorders may be the reason they cause primary Raynaud’s.
The causes of secondary Raynaud’s can be attributed to the physical conditions of the underlying medical diagnosis. These diseases can alter the characteristics of surrounding tissues, blood vessels or nerves, leading to the condition. Smoking is an additional cause, as it results in constriction of the blood vessels.
