Raynaud's phenomenon is a relatively common condition seen in primary care (especially during the autumn and winter months) that is characterised by vasospasm. This causes digits to change colour to white due to a lack of blood flow, usually brought on by cold temperatures. Affected areas subsequently turn blue due to deoxygenation and red due to reperfusion. The most common type is primary (idiopathic) Raynaud’s, affecting around 90% of people with the condition. Secondary Raynaud’s is often the initial manifestation of an associated underlying connective tissue disease. Both primary and secondary Raynaud’s can be painful, but secondary Raynaud’s can lead to complications from prolonged periods of ischaemia. In this episode, Dr Roger Henderson looks at the typical triggers for and presentation of Raynaud’s, along with lifestyle and treatment options including referral criteria.Access episode show notes containing key references and take-home points at:https://gpnotebook.com/en-GB/podcasts/dermatology/ep-149-raynauds-phenomenon (https://gpnotebook.com/en-GB/podcasts/dermatology/ep-149-raynauds-phenomenon).Did you know?
