What Is Raynaud's Phenomenon?
1. What Causes Raynaud’s Disease?
There are two main types of Raynaud’s. When the condition is diagnosed on its own and is unrelated to other medical concerns, it is called primary Raynaud’s or Raynaud’s disease. This is the most common form of the disorder and, although the cause is known, it tends to be less severe than the secondary type. Secondary Reynaud’s, or Raynaud’s phenomenon, is brought on by another medical condition.
Symptoms of Raynaud’s are not always present but rather occur as attacks or flares. These are caused by exposure to cold or stress. Even a mild change in temperature over a short period can lead to an attack. For example, taking food or ice from the freezer can cause fingers to turn blue until they are warmed.
