Functional abdominal pain disorders in children.

Background: Paediatric functional abdominal pain disorders (FAPDs) encompass a heterogenous group of medical conditions characterised by chronic abdominal pain that cannot be fully explained by another medical condition. It is important to have a structured approach to assessing patients as FAPDs can pose diagnostic challenges.

Objective: This article summarises the clinical assessment, investigations and management of paediatric patients presenting with chronic abdominal pain suggestive of FAPDs. It discusses the importance of a biopsychosocial approach to FAPDs, outlining the recommended approach to assessing and managing patients in a primary care setting.

Discussion: A diagnosis of FAPD can often be made from a thorough clinical assessment without the need for extensive investigations or referrals that can perpetuate the anxiety of patients and their family. However, it is important to identify the presence of red flag features that raise the possibility of more serious causes that must not be missed.
