Carcinoid Syndrome

Carcinoid syndrome can lead to heart damage or heart disease. Up to one-third of those with carcinoid syndrome may develop thickening in their cardiac valves. Talk to your doctor about any carcinoid syndrome symptoms you experience, as it is important to manage carcinoid syndrome to reduce risks and prevent complications. Treatments can help alleviate the symptoms of carcinoid syndrome. Lifestyle changes, such as avoiding alcohol and certain foods, may also help in managing symptoms, as certain food items and stress can trigger them.

The signs and symptoms of carcinoid syndrome include:

• Flushing of the skin and face (without sweating)
• Abdominal pain
• Feeling bloated
• Diarrhea
• Wheezing or other trouble breathing
• Fast heartbeat
• Blood pressure fluctuations
• Heart murmur
• Lower extremity swelling (if the hormones affect the right side of the heart and its valves)
