TRPV-1 neuropeptide pathway (TRPV-1 and mucosal neuropeptides)
Zeitfenster: Test day 1: mucosal biopsies are taken during upper gastrointestinal endoscopy
|
The primary outcome measure is the TRPV-1 neuropeptide pathway which includes both TRPV-1 and mucosal neuropeptide concentrations (e.g.
substance P, somatostatin), assessed with real time polymerase chain reaction (PCR) and radioimmunoassay respectively.

Symptom scores for psychopathology
Zeitfenster: 14-day period between testday 1 and testday 2
|
The Patient Health Questionnaire 9 (PHQ-9) and GAD-7 questionnaires will be used for the assessment of depressive and anxiety disorders respectively. During 7 consecutive days a digital device will be carried out for assessment of symptoms several times a day (experience sampling method/ESM). |
14-day period between testday 1 and testday 2
|
|
Symptom scores for dyspepsia
Zeitfenster: 14-day period between testday 1 and testday 2
|
Dyspeptic symptoms will be measured with two questionnaires to acquire more detailed information about complaints in patients with functional dyspepsia. The dyspepsia symptom questionnaire and the symptom checklist of the Nepean Dyspepsia Index will be used to grade the presence and intensity of dyspeptic symptoms. In addition, participants will report dyspeptic symptoms during 14 consecutive days in an end-of-day diary. During 7 consecutive days a digital device will be carried out for assessment of symptoms several times a day (experience sampling method/ESM). |
14-day period between testday 1 and testday 2

Symptom scores for quality of life
Zeitfenster: This questionnaire is fulfilled once, in the 14-day period between testday 1 and testday 2
|
Quality of life will be assessed with the Health Survey 26 (SF-36) questionnaire.
|
This questionnaire is fulfilled once, in the 14-day period between testday 1 and testday 2

Postprandial symptoms after ingestion of a standardized meal
Zeitfenster: Testday 2: Postprandial symptoms are scored using a Likert scale at 15-minute intervals for a period of 240 minutes postprandial.
