Carcinoid Flush: Carcinoids can release chemicals in your body which can cause bothersome diarrhea or flushing and other complaints, occasionally also vitamin deficiencies. A medical oncologist can prescribe medications which can control these symptoms.

Vasodilation: Flushing is due to the release of peptides into the circulation that cause dilation of blood vessels. It is characteristic of carcinoid syndrome and can be very unsettling for the patient.
