Symptom reporting by functional dyspeptics during the water load test.

Area of Science:

• Gastroenterology
• Psychosomatic Medicine

Background:

• Symptom reporting in functional dyspepsia (FD) is subjective and influenced by psychological factors.
• Somatization, depression, and alexithymia may impact how FD patients perceive and report visceral sensations.

Purpose of the Study:

• To investigate the relationship between psychological constructs and symptom reporting in functional dyspepsia patients during a water load test.
• To determine if psychological factors influence symptom recall versus immediate symptom perception in FD.

Main Methods:

• 103 functional dyspepsia patients and 67 controls underwent a 5-minute water load test.
• Participants recalled dyspeptic symptoms from the prior 2 weeks and rated symptoms during the water load.
• Psychological assessments included the Symptom Checklist-90-R, somatosensory amplification scale, and Toronto alexithymia scale.

Main Results:

• Functional dyspepsia patients reported fullness at lower water volumes and experienced more symptoms during the water load compared to controls.
• Water load volume was a better discriminator between FD patients and controls than provoked symptoms.
• Recalled symptoms in FD patients were significantly associated with psychological factors, unlike symptoms provoked during the water load.

Conclusions:

• Functional dyspepsia patients exhibit altered visceral sensitivity, reporting fullness earlier during water ingestion.
• Water load volume is a more reliable objective measure for identifying FD than symptom intensity during the test.
• Psychological distress influences the recall of symptoms in FD, but not the immediate experience of symptoms during a water load.
