The sudden flush can be caused by the loss of neural vasotonus as a result of a direct response of the smooth vascular muscles to very different stimuli. The triggering factors include:

  • Emotional stress (erythema e pudore)
  • Physical influences (heat)
  • Chemical influences (e.g. alcohol)
  • Medicines (nicotinic acid, fumarates)
  • Foodstuffs (glutamates; glutamate flush of the China Restaurant Syndrome)
  • Endocrine influences (menopause)
  • Neoplasia (mastocytosis, carcinoid syndrome, pancreatic carcinoma)
