Acid Reflux

Symptoms of acid reflux include heartburn and an unpleasant taste in your mouth.

It's not always obvious what causes acid reflux. It can be caused or made worse by some foods and drinks, stress or pregnancy.

You can help heartburn and acid reflux with things like eating smaller meals and not eating shortly before bed. Medicines like antacids can also help.

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.

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, tomatoes, 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

Simple lifestyle changes can help stop or reduce heartburn.


Do

  • eat smaller, more frequent meals

  • raise 1 end of your bed 10 to 20cm by putting something under your bed or mattress – your chest and head should be above the level of your waist, so stomach acid does not travel up towards your throat

  • try to lose weight if you're overweight

  • try to find ways to relax


Don't

  • do not have food or drink that triggers your symptoms

  • do not eat within 3 or 4 hours before bed

  • do not wear clothes that are tight around your waist

  • do not smoke

  • do not drink too much alcohol

  • do not stop taking any prescribed medicine without speaking to a doctor first

A GP may prescribe a medicine called a proton pump inhibitor (PPI) that reduces how much acid your stomach makes. PPIs include:

You'll usually need to take this type of medicine for 4 or 8 weeks, depending on how serious your acid reflux is.

Important

Go back to the GP if your symptoms return after stopping your medicine. You may need a long-term prescription.

Tests and surgery for heartburn and acid reflux

If medicines do not help or your symptoms are severe, a GP may refer you to a specialist for:

  • 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 on your stomach to stop acid reflux – called a laparoscopic fundoplication
