Carcinoid syndrome is a group of symptoms caused by tumors in the digestive system, known as carcinoid tumors. These tumors are usually found in the appendix, small intestine, rectum, or stomach, but can also appear in other places in the digestive system, such as the lungs. Carcinoid tumors are slow-growing and usually don’t spread to other parts of the body.
The main symptom of carcinoid syndrome is flushing, which is a feeling of warmth or heat in the face, neck, and chest. Other symptoms include diarrhea, abdominal pain, wheezing, shortness of breath, and heart palpitations.
Carcinoid tumors produce hormones, called serotonin and other substances, which can cause the symptoms of carcinoid syndrome. These hormones can also lead to a build-up of fluid in the abdomen, known as ascites, which can cause pain and discomfort.
If you are diagnosed with carcinoid syndrome, your doctor will recommend treatment based on the size and location of the tumor, your overall health, and your symptoms. In some cases, surgery may be recommended to remove the tumor and any affected tissue. Other treatments may include hormone therapy, chemotherapy, radiation therapy, or targeted drug therapy.
If left untreated, carcinoid syndrome can lead to serious health complications, such as heart valve damage, pulmonary hypertension, and liver damage. Therefore, it is important to seek treatment as soon as possible if you experience any of the symptoms of carcinoid syndrome.
