Acid Reflux

Acid reflux is the name given to the burning sensation you get in your throat and chest. It’s caused by stomach acid refluxing upwards.

Causes & Symptoms

Acid reflux most commonly occurs just before bedtime, when you’re lying down, largely because it doesn't take as much force for stomach acid to travel up the chest and throat.

Stomach acid helps us break down food. But as we age, our bodies are less adapted to keeping the acid from travelling up the body. That’s why you’re more likely to experience it later in life, though it can be triggered in young people too.

The symptoms of acid reflux include:

  • A burning sensation in the chest or throat after eating
  • A hot sour or salty tasting fluid in the back of your throat, accompanied by difficulty swallowing
  • Feeling sick
  • Difficulty or pain when swallowing
  • Burping

What causes acid reflux?

  • Fried and greasy foods
  • Eating too much
  • Eating too quickly
  • Fatty meats and dairy products
  • Alcohol, caffeinated drinks and spicy food, which can all cause the lower oesophageal sphincter to open.

Being overweight means there’s an increased pressure on your stomach, forcing open your oesophageal sphincter valve after eating.

But a large contributor? Stress, which can make symptoms worse. That’s because stress depletes our supply of prostaglandins, which protect our stomachs from acid. Try to get at least eight hours of restful sleep a night and cut out stressors from your life where possible.


Some people develop LPR (laryngopharyngeal reflux). The most common symptoms of LPR are a sore throat and coughing accompanied by a “lump” that doesn’t go away. If you believe you’re experiencing LPR, always consult a doctor.

Stress and anxiety can affect the body’s production of prostaglandin, which is a chemical used in the healing and repairing process throughout the body. Prostaglandin is essential to combating the damage caused by acid reflux.

If you experience acid reflux it's important to first try and monitor what you are consuming daily. Being more conscious about what you eat is an effective measure:

The most common acid reflux foods to avoid are:

  • Fatty or spicy foods
  • Oily and greasy foods
  • Dairy products
  • Creamy sauces


We know how disruptive acid reflux can be, which is why our range is designed to help ease discomfort. Our products create a protective barrier that helps prevent acid - and other aggressors like pepsin and bile - from moving up the oesophagus.

The viscous formulation at the heart of our range (Gaviscon Original, Advance and Double Action) is sodium alginate, while these products also contain antacids, which turn excess acid into water and other neutral substances. 

Dosage: Take 10-20 ml (Gaviscon Liquid) or 5-10 ml (Gaviscon Advance) after meals and at bedtime. Consider one teaspoon to equal 5 ml.

Frequent Sufferers

Repeatedly suffering from acid reflux? Don’t let it put your life on pause.


Experiencing symptoms every week? We’re here to help. Guardium can be taken for up to 24 hour relief. Guardium is a Proton Pump Inhibitor (PPI), which contains esomeprazole that works by blocking acid pumps in your stomach.

Pair it with one of our other products, such as Gaviscon Advance or Gaviscon Double Action for fast effective relief while Guardium takes effect. Do not use Guardium for more than 14 days or Gaviscon for more than 7 days.

Suffering from heartburn regularly? Dealing with a burning feeling in your chest after eating? You might have what’s known as gastroesophageal reflux disease, or GORD.

GORD presents symptoms indistinguishable from heartburn and indigestion, but occurs at a frequency that is chronic.

In such a case, you should consult with a doctor immediately.

The good news is that GORD can be effectively treated over time, and tweaks to the food and drinks you consume can limit the discomfort.
