Example
- Heartburn frequency band
- 2–3 days
- Regurgitation frequency band
- 1 day
- Epigastric pain frequency band
- 2–3 days
- Nausea frequency band
- 4–7 days
- Reflux-related sleep disturbance band
- 1 day
- Extra over-the-counter reflux medication band
- 4–7 days
Result: GerdQ 8/18 — high likelihood of GERD (approx. probability about 79%).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- >= 8
- High likelihood of GERD. Approx probability of GERD: 0-2 ~0%, 3-7 ~50%, 8-10 ~79%, 11-18 ~89%.
- Impact
- Sleep + OTC-medication subscore 0-6; a higher impact score supports escalating therapy.
What you enter
- Heartburn frequency band (0-3)
- Regurgitation frequency band (0-3)
- Epigastric pain frequency band (0-3; reverse-scored)
- Nausea frequency band (0-3; reverse-scored)
- Reflux-related sleep disturbance band (0-3)
- Extra over-the-counter reflux medication band (0-3)
How this is calculated
- Scoring
- Positive predictors (heartburn, regurgitation, sleep, OTC med) score 0-3 by days/week; negative (epigastric pain, nausea) reverse-scored 3-0. Total 0-18.
