What is functional abdominal pain?

 

Functional abdominal pain is a diagnosis that is part of the profile of some functional gastrointestinal (GI) disorders. Functional gastrointestinal disorders are disorders where there is a malfunction in the normal activities of the GI tract, but there are no structural abnormalities to explain the malfunction.  There are no abnormal tests or x-rays or other images that explain the pain.  Even though there are no tests to definitively diagnose it, functional abdominal pain is a real, legitimate diagnosis and is not “all in your head.”  The disorder is more about patient symptoms and patient experience, not about structural or anatomical issues within the gut.  The gut is not inflamed or infected, it looks normal.  The issue is the gut is not communicating signals properly, resulting in chronic abdominal pain.
