Individuals with digestive problems that cannot be diagnosed could be experiencing functional gastrointestinal disorders. Could understanding the types help in developing effective treatment plans?

Functional gastrointestinal disorders, or FGDs, are disorders of the digestive system in which the presence of structural or tissue abnormality cannot explain symptoms. Functional gastrointestinal disorders lack identifiable biomarkers and are diagnosed based on symptoms. (Christopher J. Black, et al., 2020)
FGDs used diagnoses of exclusion, meaning that they could only be diagnosed after organic/identifiable disease was ruled out. However, in 1988, a group of researchers and healthcare providers met to devise strict criteria for the diagnosis of the various types of FGDs. The criteria is known as the Rome Criteria. (Max J. Schmulson, Douglas A. Drossman. 2017)
A comprehensive list as described by the Rome III criteria (Ami D. Sperber et al., 2021)
Infant/Toddler (Jeffrey S. Hyams et al., 2016)
Child/Adolescent
Although the Rome criteria allow the diagnosis of FGDs to be symptom-based, a healthcare provider may still run standard diagnostic tests to rule out other diseases or look for structural problems resulting in symptoms.
Although no visible signs of disease or structural problems may be identified as causing the symptoms, it does not mean that they are not treatable and manageable. For individuals who suspect they may have or have been diagnosed with a functional gastrointestinal disorder, it will be essential to work with a healthcare provider on a working treatment plan. Treatment options can include: (Asma Fikree, Peter Byrne. 2021)
