In flushing (synonyms: Abnormal Flushing; Flushing; Flush; Facial Flushing; Rubeosis faciei; Excessive Flushing; ICD-10-GM R23.2: Facial Flushing [Flush]) is a seizure-like violent flushing of the skin of the face and neck region (possibly also of the upper body), which is due to a sudden expansion of blood vessels and an associated increase in blood volume.
Flush may occur spontaneously or after great exertion.
There are many causes of flush. In addition to emotions (e.g. stress), foods, stimulants (e.g. alcohol), diseases, medications and neurotransmitters (e.g. serotonin) can be the cause of flush.
Flushing can be a symptom of many diseases (see under “Differential diagnoses”).
Sex ratio: Women are more often affected than men, as most cases occur during menopause.
Frequency peak: Flushing occurs predominantly in childhood and less frequently in adulthood.
Course and prognosis: A flush (reddening of the skin) is often experienced as unpleasant by those affected. If it is known what causes a flush, these should be avoided if possible. In severe cases, a psychotherapist may be consulted, as often insecure people are prone to excessive flushing.
