What Is Raynaud's Disease? Here's The Symptoms Of This Rare Condition That Cause White Or Blue Fingers & Toes

Covering your fingers, toes, and face with proper winter wear can help prevent the condition.

During extreme winters, some of our fingers or toes are seen to develop extreme paleness. Though many of us ignore this condition, it is important to pay close attention to it as it may be due to Raynaud's disease.

What is Raynaud's disease?


This rare condition, that is usually triggered by low temperatures, is caused due to the narrowing of blood vessels, according to Mayo Clinic. It may also be caused due to stress factors. The ailment restricts the flow of blood to some parts of the body, causing a tingling sensation and numbness. Usually, it has been observed that the affected blood vessels are in the fingers and the toes. Later, they affect body parts like the lips and nose. However, the exact cause of the condition is not known. 


There are stages of the illness, primary and secondary. The primary stage is not to be feared as the condition gets resolved without going to the doctor. However, the secondary condition is severe and is connected to an underlying disease. According to the Mayo Clinic, the secondary conditions are usually seen after the age of 40. Carpal tunnel syndrome, smoking, connective tissue disease, artery disease are some of the causes that can lead to secondary Raynaud blood flow restriction in the body.


A severe case of secondary Raynaud can damage the tissue in areas of limited blood circulation. If an artery is completely blocked, it can cause sores too. These are usually difficult to treat. In worst scenarios, if the condition is left untreated, it might require amputation of the affected part.  

Vulnerable people 

Primary Raynaud

The temperature of your surrounding is also an essential factor. According to researches, those living in colder places are more susceptible to the condition than those living in warmer places. Family history is another factor. If any first-degree family member such as a parent or sibling has the condition, you are prone to develop it as well. This condition is usually observed more in women in comparison to men. Symptoms of primary Raynaud's disease are usually observed in 15-30 year-olds.

Secondary Raynaud

Those that work with high-vibrational tools such as jackhammers are prone to the disease. Apart from that, people who take medication that contains beta-blockers are also at the risk of developing the condition, according to Medical News Today. Exposure to smoking and chemicals, such as vinyl chloride can cause secondary Raynaud. 

Treatment and Precautions

It is vital for patients to consult a physician to understand the gravity of the condition. However, you can also take precautionary measures to reduce the intensity of the condition. Wearing appropriate woolen clothes to protect your fingers, toes, and faces during harsh winters and working on reduced stress-levels can help prevent the condition.
