Functional Gastrointestinal disorders are common conditions that affect the digestive system. They are called "functional" because they relate to how the gut functions, rather than to structural or biochemical abnormalities. They are also called Disorders of Brain-Gut interaction. They can cause significant and recurrent symptoms but without a disease process or ongoing damage to the mucosa.
