Gastro-oesophageal reflux disease (GORD) occurs when stomach acid leaks back up into the oesophagus. This is known as acid reflux. The oesophagus is the tube that runs from your throat to your stomach.
GORD is often a chronic condition, which means that if you have it, you may experience recurring episodes for the rest of your life.
The symptoms of GORD may be improved by making lifestyle changes that affect acid reflux, such as eating smaller meals, and if you smoke, giving up.
There are also a number of medicines that can be used to relieve the symptoms of GORD. More severe cases of the condition may require surgical treatment.
Repeated episodes of GORD can make the lining of your oesophagus inflamed (known as oesophagitis).
GORD is a common condition, and it's one of the most frequent causes of indigestion and heartburn. It is estimated that 10 to 20% of people will have acid reflux at least once a week.
