Frequently Asked Questions (FAQs)


Q: What is acid reflux?

A: There is a valve-like structure called the sphincter between the food pipe and stomach. This valve prevents the acid and the food in your stomach from coming back into the food pipe. When this valve is weak or damaged, acid starts entering the stomach, causing heartburn, difficulty in swallowing and food regurgitation.
