Understanding Raynaud's Phenomenon for Diabetics

Raynaud's Phenomenon causes discoloration and nail issues due to vasospasms, mainly affecting fingers and toes.

Named after Maurice Raynaud, it results from vasospasms reducing blood supply, triggered by stress or cold.

Includes Primary Raynaud's (idiopathic) and Secondary Raynaud's (caused by other factors).

Primary form can progress to secondary form; extreme cases may lead to necrosis or gangrene.

Emotional stress and cold are classic triggers for this vasospastic disorder.

Hyperactivation of the sympathetic system causes severe vasoconstriction, leading to tissue hypoxia.

Chronic cases can result in atrophy, ulcers, and rare occurrences of ischemic gangrene.
