Functional abdominal pain is chronic and recurrent pain in the abdominal region that does not have an identifiable physical or organic cause. Along with other gastrointestinal functional disorders, as a group it constitutes the most common cause of abdominal pain. It is constant or near-constant without a relationship to physiological events, but can be associated with psychosocial stressors. Patients often suffer from other functional morbid conditions such as fibromyalgia and migraine which altogether result in poor quality of life and increased heathcare utilization. The condition is frequently explained by dysfunctional gut motility and or dysfunctional visceral sensation. Patient’s symptoms often require testing but it is a diagnosis of exclusion, and can be differentiated from other functional GI disorders using several criteria. Like other chronic pain conditions, the etiology and pathophysiology are not yet well understood, but it involves a central process resulting in visceral hyperalgesia from peripheral and or central sensitization of the afferent system. Management of FAP aims to provide symptom relief and improve quality of life through a multi-faceted approach both pharmacologically and psychologically. The best outcome is achieved with the establishment of a healthy patient–physician relation that is combined with psychological interventions aimed at building pain coping skills.
