Raynaud’s Syndrome (Raynaud’s Disease/Phenomenon)

What is Raynaud’s Syndrome (Raynaud’s Disease/Phenomenon)?

Raynaud’s is characterised by vasospasm (sudden contraction of a blood vessel) of the small arteries that supply blood to the skin, typically in the fingertips or toes. There are two types of Raynaud’s, Primary Raynaud’s and Secondary Raynaud’s. ● Primary Raynaud’s, also referred to as Raynaud’s Disease, is caused by an underlying associated medical condition that can cause vasospasm. ● Secondary Raynaud’s, also referred to as Raynaud’s Phenomenon, is caused by a separate underlying condition such as a connective tissue disease, atherosclerosis (thickening, hardening and/or plaque build-up within arteries), carpal tunnel syndrome, repetitive trauma, smoking or even certain medications.

Raynaud’s presents as coldness, numbness, stinging, pallor (whitening), and/or blueness of the fingertips or toes due to the reduced blood flow caused by vasospasm. This condition is triggered by cold temperatures or emotional stress, which can exacerbate symptoms. In severe cases, ulcers or sores may develop on the affected digits due to prolonged reduction in blood flow.

Primary Raynaud’s, or Raynaud’s Disease, typically without an underlying associated medical condition, although genetic factors may play a role. Episodes of vasospasm in Primary Raynaud’s are usually less severe and easier to manage compared to Secondary Raynaud’s.

Secondary Raynaud’s, or Raynaud’s Phenomenon, is often associated with other health conditions that affect the immune system, blood vessels, or nerves. These underlying conditions may include autoimmune diseases like lupus or scleroderma, vascular diseases like atherosclerosis, or occupational factors such as repeated use injuries or exposure to vibrating machinery.

Management of Raynaud’s involves lifestyle changes to avoid triggers like cold temperatures and stress, wearing warm clothing, and sometimes medications to improve blood flow or reduce the frequency of vasospastic episodes. Understanding the underlying cause, especially in Secondary Raynaud’s, is crucial for effective treatment and management of the condition.If you are suffering from Raynaud’s Syndrome, we have a team who is ready to help you and get you on the road to recovery.
