- Gender: ALL
- Minimum Age: 33 Years
- Maximum Age: 65 Years
- Healthy Volunteers: t

Study Arms:
- Healthy Volunteers (Type: EXPERIMENTAL): Healthy volunteers who are matched (age, weight, gender) to the general patient population undergoing manometry and pH monitoring for GERD will undergo the same procedures to determine pH levels in people without reflux symptoms as compared to pH levels in those patients who have been diagnosed with reflux.

Based on this trial design, predict the completion outcome and termination type (if applicable).
