Heartburn is a burning feeling in the chest caused by stomach acid travelling up towards the throat (acid reflux). If it keeps happening, it’s called gastro-oesophageal reflux disease (GORD).

The main symptoms of acid reflux are:

  • heartburn – a burning sensation in the middle of your chest
  • an unpleasant sour taste in your mouth, caused by stomach acid

You may also have:

  • a cough or hiccups that keep coming back
  • a hoarse voice
  • bad breath
  • bloating and feeling sick

Your symptoms will probably be worse after eating, when lying down and when bending over.

Causes of heartburn and acid reflux

Lots of people get heartburn from time to time. There’s often no obvious reason why.

Sometimes it’s caused or made worse by:

  • certain food and drink – such as coffee, alcohol, chocolate, and fatty or spicy foods
  • being overweight
  • smoking
  • pregnancy
  • stress and anxiety
  • some medicines, such as anti-inflammatory painkillers (like ibuprofen)
  • a hiatus hernia – when part of your stomach moves up into your chest

Tests and surgery for heartburn and acid reflux

If medicines don’t help or your symptoms are severe, your consultant may suggest:

  • tests to find out what’s causing your symptoms, such as a gastroscopy (where a thin tube with a camera is passed down your throat)
  • an operation to stop acid reflux – called a laparoscopic fundoplication
