What is carcinoid?

Carcinoid syndrome refers to a group of symptoms that occurs when a type of tumor called a neuroendocrine tumor (NET) releases hormones into the bloodstream. The symptoms include diarrhea and facial flushing. These tumors can be cancerous or non-cancerous and most arise in the gastrointestinal tract, though they can be found in other organs as well.

Symptoms of carcinoid

  • Facial flushing

  • Spots in mouth

  • Noisy breathing; e.g. wheezing, rattling

  • Feeling down

Questions your doctor may ask to check for carcinoid

Your doctor may ask these questions to diagnose carcinoid

  • Do you have a red or flushed face?

  • Do you have spots or boils in your mouth?

  • Is your breathing noisy; e.g. wheezing, rattling?

  • Have you been feeling depressed recently?

Treatment for carcinoid

Treatment involves treating the tumor itself, e.g. through surgery, radiation, or chemotherapy. There are also medications which can slow down production of the hormones responsible for some of the symptoms. In the meantime, simple steps like cool towels on the face and avoiding alcohol can relieve symptoms of hot flashes.
