Acid Reflux

Acid reflux causes heartburn which 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 after meals and 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 tasting fluid in the back of your throat, accompanied by difficulty swallowing
  • Feeling sick
  • Difficulty or pain when swallowing
  • Wheezing
  • Burping

In the majority of cases, acid reflux is a natural response to the stomach acid irritating an unprotected oesophagus.

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 and make necessary lifestyle changes that will help lessen or stop reflux. 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

Repeat Sufferers

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


Acid reflux can be natural condition, but if you’re regularly feeling the effects, then it might not be due to natural causes. Best to consult your doctor.

If you are using PPI, you can complement it with using Gaviscon Double Action.

If symptoms persist, you might have a disease known as GERD.

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 GERD.

GERD 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. GERD can cause you to develop ulcers and it can even restrict your breathing, so a professional’s advice is required.

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