What is acid reflux?

Acid reflux is also known as heartburn, acid indigestion and gastric reflux.

It’s caused when some of the acidic stomach contents go back up into the oesophagus (the tube that carries food down from your mouth). This creates a burning pain in the lower chest area, often after you’ve just had a meal.


What are the acid reflux symptoms?
