The Clinical Course and Factors for the Progression of Uninvestigated Dyspepsia to Functional Dyspepsia

Dyspepsia is one of the most common gastrointestinal diseases. This disease was defined as predominant epigastric pain lasting for at least 1 month, which can be accompanied with other symptoms, such as epigastric fullness, and early satiety. Despite dyspepsia symptoms lasting for ≥1 month represented clinical problem, a longer duration of 6 months or more after first-onset symptom was required for the diagnosis of functional dyspepsia based on ROME IV criteria. It was unclear about the natural procession of first-onset dyspepsia to functional dyspepsia assessed by Rome IV or Asia criteria and possible factors associated with this progression.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Functional dyspepsia defined by ROME IV criteria	Met the following criteria: by one or more of the following symptoms: postprandial fullness, early satiation, epigastric pain, and epigastric burning that are unexplained after a routine clinical evaluation, Criteria fulfilled for the last 3 months with symptom onset at least 6 months before diagnosis.	6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Global Overall Symptom score (GOSS)	The GOSS consists of 10 cardinal items (epigastric pain, epigastric discomfort, Heartburn, acid regurgitation, upper abdominal bloating, belching, nausea, early satiety, postprandial fullness, other epigastric symptoms(eg. epigastric burning). Each item can be scored from 1 (no) to 7 (worst).	1month, 3 months, 6 months
Short Form of Nepean Dyspepsia Index (SF-NDI)	The SF-NDI consists of 10 questions regarding the effects of dyspepsia symptoms ("stomach problems") on different aspects of life (tension, interference with daily activities, eating/drinking, knowledge/control, and work/study). Each response can be from 1 (not at all affected) to 5 (extremely affected), or 0 (N/A), for a total summed score out of 50.	1month, 3 months, 6 months
Hospital anxiety and depression scale	Anxiety and depression of patients are assessed by using Hospital Anxiety and Depression Scale.It contains 14 items (7 anxiety and 7 depression), which assess symptoms experienced during the past week on a 0-3 scale. A subscore of > 8 for depression or anxiety would indicate a clinical case.	1month, 3 months, 6 months
Functional dyspepsia defined by Asia criteria:	Met the following criteria: by one or more of the following symptoms: postprandial fullness, early satiation, epigastric pain, and epigastric burning that are unexplained after a routine clinical evaluation, the symptoms duration≧3 months.	3 month
Number of participants subclassified into different subtypes of functional dyspepsia defined by ROME IV criteria	Functional dyspepsia was classified into three subgroups：(1) Postprandial Distress Syndrome, defined as Bothersome postprandial fullness or/and Bothersome early satiation. (2) Bothersome epigastric pain AND/OR Bothersome epigastric burning. (3) mixed syndrome, defined when postprandial distress syndrome and epigastric pain syndrome presented simultaneously.	6 months
Quality of Life scores	Quality of Life scores assessed by Patient-reported outcomes measurement information system (PROMIS) Global-10 questionnaire. PROMIS Global-10 is a newly validated 10-question survey used to assess health care-related quality of life measures for the general population. It's a 10-item patient-reported questionnaire in which the response options are presented as 5-point (as well as a single 11-point) rating scales. These scores are then standardized to the general population, using the "T-Score". The average "T-Score" for the United States population is 50 points, with a standard deviation of 10 points. Higher scores indicate a healthier patient and a better quality of life.	1month, 3 months, 6 months
Self-reported severity of symptoms by patients	Patients rated the severity of dyspepsia as mild, moderate, and severe by themselves	1 day
Number of participants with other functional gastrointestinal diseases defined by ROME IV criteria	Recurrent functional dysphagia， reflux hypersensitivity， irritable bowel syndrome， etc.	1 day
