What is heartburn?

Heartburn is a symptom of acid reflux. It occurs when acid produced by the stomach travels up towards the throat and causes a burning sensation in the middle of your chest.

You may also experience a cough, hiccups, bad breath and nausea when suffering from acid reflux.

Although acid reflux is not a serious condition it may be a symptom of gastro-oesophageal reflux disease (GORD), a long-term form of acid reflux.

If you often experience heartburn and acid reflux it is recommended that you seek advice from your doctor, as they will be able to prescribe a medicine known as a proton pump inhibitor (usually either omeprazole or lansoprazole) which can help to reduce the amount of stomach acid that is produced by your stomach.
