Diagnosis of FGIDs in children primarily relies on clinical evaluation and the use of Rome IV criteria, which provide specific diagnostic guidelines for different FGIDs. The process includes:
1. Detailed medical history: To understand the child's symptoms, duration, and impact on daily activities. 2. Physical examination: To rule out any organic causes. 3. Minimal diagnostic testing: As FGIDs are functional disorders, extensive testing is usually unnecessary unless red flags are present.
