Flushing Can be temporary or constant and usually appears suddenly on the face or neck. The flush looks deep red or purple. When this occurs, you may also feel warm, unpleasant, and have a rapid heartbeat. The flush may last only a few minutes in early stages of carcinoid syndrome and may last hours during later stages. Diarrhea Can occur with flushing or by itself.
Stools are watery and the diarrhea can be mild to severe.
Episodes can occur several times a day and can interfere with daily life. Patients with severe cases of diarrhea often have trouble leaving their homes for work, social functions, or activities that require being away from home and on the move for a long time. Electrolytes carry electrical charges or messages throughout your body. Without enough water and electrolytes, proper digestion cannot occur and your body cannot get the nutrients that it needs. This can worsen the weight loss, weakness, and fatigue that may have already been caused by the loss of fluids and electrolytes.
