Brief Summary
GERD is common in Indian population and the normative data which is used to diagnose \& manage GERD and its complications are based on western data which is not validated in the Indian population. Although normative data is available for commonly used twenty-four impedance-pH parameters, their global application has limitations, stemming from use of small healthy volunteer cohorts from few countries for normative data. At present, there is no normative data for twenty-four hours impedance-pH monitoring in Indian population. The aim of this study is to obtain a new set of normal values specific for the Indian population.

Outcome Measures
Primary Outcomes (1)
Normative values for impedance-pH monitoring in healthy Indian population.
There is no normative data for impedance-pH monitoring specific to indian population. The study aims to generate a reference value for the same by enrolling healthy individuals.
six months
Interventions
24 hour pH impedance monitoring will be done on healthy subjects so that normative data specific to indian population can be generated.
Eligibility Criteria
The study will enroll only healthy asymtomatic subjects, so that normative data can be generated.
You may qualify if:
- Healthy individual \> 18 years of age
- Not on any acid lowering drug from at least 7 days.
You may not qualify if:
- Thoracic or digestive foregut surgery,
- Alcohol consumption \>40 g/day,
- Use of medications that alter intragastric acidity or oesophageal motility
- History of diabetes mellitus,
- Neurological disorders
- Chronic gastrointestinal disease
- Any subject with upper GI symptoms like pain, burning, belching, bloating, dysphagia \& aerophagia
