Flushing is a key symptom of carcinoid syndrome, affecting the face, neck, and chest. Discover why it happens and what it means.
The Flushing Phenomenon
Flushing in carcinoid syndrome is characterized by sudden redness in the face, neck, and upper chest, sometimes lasting up to 30 minutes. It can bring a mild burning sensation and changes in blood pressure and heart rate.
Triggers of Flushing
Flushing episodes can occur spontaneously but are often triggered by certain actions such as eating, drinking alcohol, or stress. These triggers can cause the body's blood vessels to widen, leading to the red, warm sensation.
