1. What is the GERD-Q Score?

The GERD-Q (Gastroesophageal Reflux Disease Questionnaire) is a validated diagnostic tool for GERD. It assesses symptom frequency over the past week to help diagnose GERD and evaluate its severity.

2. How Does the Calculator Work?

The calculator sums scores from six symptom domains:

Where each symptom is scored:

• 0 - No days with symptom
• 1 - 1 day with symptom
• 2 - 2-3 days with symptom
• 3 - 4-7 days with symptom

3. Interpretation of Scores

Score Ranges:

• 0-5: Unlikely GERD
• 6-10: Possible GERD
• 11-18: Likely GERD

Clinical Use: Scores ≥8 suggest GERD with 65% sensitivity and 71% specificity. Higher scores correlate with more severe symptoms.

4. Using the Calculator

Instructions: For each symptom, select the frequency that best matches your experience over the past week. The calculator will sum all scores.

5. Frequently Asked Questions (FAQ)

Q1: Is GERD-Q diagnostic for GERD?
A: While helpful, GERD-Q is a screening tool. Endoscopy or pH monitoring may be needed for definitive diagnosis.

Q2: How often should I complete this questionnaire?
A: For monitoring, complete weekly. For diagnosis, a single assessment may suffice.

Q3: What if my score is borderline (6-10)?
A: Borderline scores may warrant repeat testing or further evaluation with your healthcare provider.

Q4: Does this replace doctor visits?
A: No. Always consult a healthcare professional for persistent symptoms, especially with alarm features (weight loss, bleeding).

Q5: Can medications affect my score?
A: Yes. Ideally complete the questionnaire off acid-suppressing medications, unless assessing treatment response.
