* symptom onset at least six months before diagnosis. NOTES * The above criteria must be fulfilled for the last three months AND No evidence of structural disease (including at upper endoscopy) that is likely to explain the symptoms 3. The most famous criteria for diagnosis of functional dyspepsia are the ROME IV criteria ( reference): Functional Dyspepsia ROME IV Criteria. Your doctor has to perform an endoscopy and some tests to ensure no other (organic) causes of dyspepsia.Diagnosing (functional) dyspepsia necessitates the exclusion of other causes of dyspepsia (such as peptic ulcers, h.However, you can not diagnose yourself with functional dyspepsia.

Motility diseases are associated with dyspepsias such as gastroparesis (slow motility of the stomach), Rapid gastric emptying, impaired gastric accommodation to meals, and antral hypermotility ( reference). Functional dyspepsia is also called (idiopathic) as we don’t fully understand its origin.Īll we have are theories with little or inconsistent evidence in research.Īnd here are the most common theories about functional dyspepsia. We still don’t know the exact causes and mechanism of dyspepsia. One study estimated that 75% of dyspepsia causes are functional dyspepsia (FD), and only 25% are due to organic reasons. However, Functional dyspepsia is still the most common cause of dyspepsia.
