Acid reflux is when acid comes up from the stomach, irritating the oesophagus and causing symptoms of heartburn. It happens when the valve at the top of the stomach, called the lower oesophageal sphincter, opens too often or does not close tight enough. This causes stomach acid to seep back up into the oesophagus, damaging it and causing the burning sensation we know as heartburn.
