What is carcinoid syndrome diarrhea?

Carcinoid syndrome diarrhea (CSD) is one of the most common symptoms of functioning neuroendocrine tumors (NETs)

Symptoms of CSD include urgency, frequency, and watery stools.

What causes CSD?

CSD occurs when a NET cell produces too much serotonin.

Serotonin: More than the “happy” hormone

Serotonin is a hormone that is made and released by cells in both the brain and the gut. It’s sometimes referred to as the “happy” hormone because serotonin produced in the brain helps regulate mood. But serotonin made in the gut plays an important role in other bodily functions, including bowel movements.

Too much of a good thing

In people with carcinoid syndrome (CS), serotonin levels can be significantly greater than average. An overproduction of serotonin by NET cells can lead to diarrhea, flushing, wheezing, fibrosis, and carcinoid heart disease, among other effects.

Over time, too much serotonin may increase the amount of fluid in the gut. It can also speed up the function of the gut, which may cause frequent, unpredictable diarrhea. Even with somatostatin analog (SSA) treatment, some patients with CS continue to experience diarrhea.

The science behind CSD

When cells grow abnormally, they form a tumor.

Neuroendocrine tumor producing too much of the hormone serotonin

When a tumor forms in the neuroendocrine system, it may produce too many hormones, such as serotonin.

Hormone serotonin communicating with the gut to help with digestion

Hormones are one way your body’s cells communicate with each other to help with bodily functions. For example, serotonin is a hormone that communicates with your gut to help with digestion.

Neuroendocrine tumor cell producing too much serotonin

When NETs produce too much serotonin, your body’s natural serotonin levels can be thrown off balance. The extra serotonin in the gut can lead to CSD.
