Acid reflux is a condition that happens when stomach acid goes up into the throat. It most commonly causes a burning sensation in your throat or chest.
Some people experience it from time to time. However, for others, it can be an ongoing condition. Either way, knowing the symptoms and when they occur is the best way to treat them - keep reading to learn more.
Acid reflux happens when the stomach acid goes back up into your throat. It is related to the valve between your stomach and the throat, called the LES (lower oesophageal sphincter).
The LES usually stops acid from coming back up, but the acid can escape through the open valve and cause symptoms when it's weakened.
This phenomenon is generally linked to your diet and is common in people who are overweight, smoke, have a condition like a hiatal hernia, are pregnant or take certain medications.
The most common symptoms of acid reflux include heartburn, a sour taste in your mouth, and indigestion.
The main symptom is heartburn. Heartburn feels like a burning sensation in the chest. It usually starts in the upper part of the stomach and spreads to the chest area.
Many people think that severe heartburn feels like a heart attack, but the symptoms are not the same.
A heart attack usually feels like an uncomfortable sensation in the centre or left side of your chest that spreads to your arm, neck, or jaw. It is usually described as a pressure, squeezing, or fullness sensation. People may also feel tired, dizzy, or have shortness of breath. These are not common symptoms of acid reflux.
When you get heartburn, it’s common to experience an unpleasant taste in your mouth. This occurs when the acid leaks into your throat.
It can also cause:
Dyspepsia, which is also known as indigestion, is a common sign of acid reflux.
People with indigestion may have the following symptoms:
It’s easy to confuse the terms indigestion, heartburn and acid reflux as they all are very similar. Indigestion and heartburn can also occur at the same time.
Unlike heartburn, indigestion can be caused by other digestive conditions, such as gallbladder inflammation and irritable bowel syndrome (IBS).
Symptoms of heartburn usually happen after eating. This is especially true if you have eaten fatty, spicy or acidic foods.
Heartburn can also occur when you lie down or bend over because this position makes it easier for the acid to travel up to your throat. This is why it's common to experience symptoms of acid reflux at night because you’re lying down.
Some factors can make your symptoms worse, including food and lifestyle choices.

For most people, symptoms can last for a few minutes up to a few hours. Symptoms should ease by themselves once your food has been digested or you have stood up.
If you have a condition that is causing reflux, symptoms may occur chronically. Bouts may last longer and your symptoms may be more frequent.
Gastro-oesophageal reflux disease (GORD), sometimes spelt GERD, is a more severe form of acid reflux. The symptoms are more frequent and tend to be worse.
GORD is also more likely to cause serious complications, such as:
GORD can lead to oesophageal cancer. However, this is rare and only affects around 3-13% of people with Barrett’s oesophagus.
You can treat mild acid reflux symptoms with lifestyle changes such as changing your eating habits, weight loss and quitting smoking. Your pharmacist can also recommend over-the-counter medications like antacids for quick symptom relief.
For more severe acid reflux cases, your doctor may prescribe you a type of prescription medication called PPIs (proton pump inhibitors). They work by directly reducing stomach acid production.
There are a few telltale signs that you should see your GP about your symptoms.

While your symptoms may not mean you have something serious, your doctor will want to rule out any serious causes.
