It is called Raynaud’s disease or Raynaud syndrome; however, it is often considered one of the most common disorders, especially in cold temperatures, causing limited blood supply to the fingers. Consequently, it affects a considerable portion of a person’s skin color to white and dark red compared to their normal skin tone. In fact, this disorder reaches millions of individuals in all walks of life worldwide.
What is Raynaud’s Phenomenon?
Raynaud’s phenomenon is a condition where the blood vessels in the extremities constrict, reducing the flow of blood. The condition mainly affects the fingers and toes, though sometimes, it can affect other areas, such as the ears, nose, or tongue. It usually occurs due to cold temperatures or emotional stress. The small arteries that supply blood to the skin constrict too much, reducing the blood supply to the affected area.
Types of Raynaud’s Phenomenon
Raynaud’s phenomenon can be classified into two: Primary and Secondary.
Primary Raynaud’s phenomenon is the most common form, without an identifiable underlying cause.
Secondary Raynaud’s phenomenon is associated with other health conditions, such as rheumatic diseases like scleroderma or lupus. Though less common, this form is more serious because of the damage that can be done to the blood vessels.
Symptoms
- Change in skin color: As the blood flow decreases, the color of the affected area may change from white to blue to red.
- Numbness or cold sensation: Affected areas, such as fingers or toes, may feel numb or cold, similar to the sensation of a body part “falling asleep,” caused by insufficient oxygenated blood.
- Tingling: This occurs as blood flow returns to the affected body part.
- Painful sores: Frequent attacks may cause painful sores on fingers or toes, and in extreme cases, tissue may die from a lack of oxygen.
Treatment
For most, lifestyle adjustments are enough to keep Raynaud’s phenomenon at bay. However, if the attacks are frequent or severe, medical intervention is required.
