The triad of carcinoid syndrome is a group of three symptoms that are often associated with carcinoid tumors, which are rare slow-growing tumors that typically develop in the digestive system. The three symptoms that make up the triad of carcinoid syndrome are flushing, diarrhea, and wheezing.
Flushing is the most common symptom of carcinoid syndrome and is caused by the release of serotonin from the tumor. It is characterized by facial redness, warmth, and a sensation of heat. It can also affect other areas of the body like the neck, chest, and arms.
Diarrhea is another common symptom of carcinoid syndrome. It is caused by the release of hormones from the tumor that affect the small intestine. Diarrhea can range from mild to severe and can last for several hours.
Wheezing is the third symptom of carcinoid syndrome and is caused by the release of certain hormones that affect the lungs. It is characterized by a whistling sound while breathing and is often worse during exercise.
Although the triad of carcinoid syndrome is a relatively rare condition, it is important to be aware of its symptoms and to seek medical advice if any of them are present. Early diagnosis and treatment can help to manage the symptoms and may even prevent the tumor from progressing.
