Raynaud’s Disease

Raynaud’s disease is caused due to hyperactivation in the sympathetic nervous system. The sympathetic nervous system keeps our body in equilibrium. But its hyperactivation causes extreme vasoconstriction in the body.

In simple words, when our body is subjected to cold temperatures, then the blood circulatory system of toes and fingers tries to conserve the heat. The heat conservation is done by narrowing the vessels which limits the blood supply to toes and fingers temporarily.

But in people suffering from Raynaud’s Syndrome, the blood vessels instead of narrowing temporarily, shuts down the blood flow completely.

Types of Raynaud’s Disease

Mainly there exist two types of Raynaud’s Disease:

1. Primary Raynaud’s: It is the most common form of Raynaud’s disease. It is also less severe than Secondary Raynaud’s and that’s because it isn’t caused due to some associated medical condition that could provoke vasospasm.

 

2. Secondary Raynaud’s: This is known as Raynaud’s phenomenon and is caused due to an underlying associated medical condition. It’s less common than Primary Raynaud’s but it is more serious.

Causes of Raynaud’s Syndrome

Secondary Raynaud's are what is commonly called Raynaud’s Syndrome and its causes are as follows:

1. Disease of Connective tissues: People who suffer from scleroderma, a disease which causes skin to harden, are more prone to Raynaud’s syndrome. These symptoms are commonly linked to rheumatoid arthritis, lupus and Sjogren’s syndrome.

2. Diseases of Arteries: Diseases which affects arteries are associated with Raynaud’s Syndrome. Disease like Atherosclerosis in which plaque buildup in blood vessels connecting the heart and Buerger’s disease in which blood vessels of feet and hands become inflamed are associated with Raynaud’s Syndrome. Primary pulmonary hypertension; a type of high blood pressure affecting lung arteries are also linked to Raynaud’s.

3. Carpal Tunnel Syndrome: This disease in which pressure is put on nerves innervating the hand, increases susceptibility to Raynaud’s symptoms.

4. Smoking: Due to smoking, blood vessels become constricted causing Raynaud’s Syndrome.

5. Repetition or Vibration: People whose job includes frequent vibrational movements like jackhammer operators are susceptible to Raynaud’s syndrome. Also people who pursue any job or hobby which have repetitive movements like playing piano, guitar or typing are more at risk of Raynaud’s syndrome.

6. Certain medication: Drugs like beta blockers, used to treat high blood pressure; medication for migraine containing ergotamine or sumatriptan; some chemotherapy agents; medication for attention defecit / hyperactivity disorder and other drugs which cause blood vessels to narrow are usually linked with Raynaud’s.

7. Injuries: Raynaud’s Syndrome might also appear after some injuries like broken wrist or frost bite.
