Raynaud’s phenomenon is a condition that affects circulation to certain parts of the body, mainly fingers and toes. It is caused by vessels in these areas constricting more than usual in response to cold or stress. The affected areas slowly turn white or bluish and are cold or numb. When circulation is returned to normal, the skin may become reddened and throb or tingle. Raynaud’s is not fatal, but ongoing episodes can hurt and interfere with daily activities.
Causes of Raynaud’s Phenomenon
There are two types of Raynaud’s phenomenon: primary and secondary.
- Primary Raynaud’s – This is the most common type and is found without any underlying medical condition. It is generally minor and tends to affect those living in colder climates.
- Secondary Raynaud’s – This type is associated with other illnesses, including autoimmune illnesses like lupus or scleroderma. It may also be caused by repetitive hand movements, certain medications, or chemical exposure that affects blood vessels.
Although it is never clear what causes it, Raynaud’s phenomenon is more common in women and particularly those under age 30 and has a potential genetic factor.
Symptoms of Raynaud’s Phenomenon
Raynaud’s attacks are typically triggered by cold exposure or emotional stress. They are commonly associated with a three-stage colour change in the affected areas:
1. White (Pallor) – Reduced circulation causes the skin to be pale.
2. Blue (Cyanosis) – Blue colouration is produced by a prolonged lack of oxygen.
3. Red (Rubor) – After circulation is restored, there can be flushing of the skin and a sensation of throbbing or tingling.
The attacks may last for a few minutes to hours and may affect not only fingers and toes, but also nose, ears, or lips in some. In severe forms, individuals may also develop ulcers or sores on fingertips as a result of chronic vasoconstriction.
