GERD Treatment in Singapore: Managing Acid Reflux and Heartburn

Last updated: 29 Oct 2026

Most people have heartburn now and then, perhaps after a large supper or a spicy meal. When it keeps coming back, though, it may be a sign of gastro-oesophageal reflux disease (GERD, also written GORD).[1][2] GERD is common and usually manageable, but it is worth taking seriously: over time, repeated acid exposure can inflame and damage the lining of the food pipe. This guide explains the acid reflux symptoms to look out for, when tests are needed and the main options for GERD treatment in Singapore and elsewhere.

Acid reflux, heartburn and GERD: what's the difference?

• Acid reflux is when stomach contents, including acid, flow back up from the stomach into the oesophagus (food pipe). Many people have it occasionally.[2]
• Heartburn is the burning feeling in the middle of the chest that reflux often causes.[1][2]
• GERD is the term doctors use when reflux happens often or causes troublesome symptoms or complications.[1][2]

A ring of muscle at the bottom of the oesophagus, the lower oesophageal sphincter, normally stops stomach contents coming back up. GERD can develop when this muscle is weak or relaxes when it shouldn't.[3]

Dr Ling Khoon Lin talks about gastric reflux in a short video on reflux and heartburn, which you may find a useful companion to this article.

Common acid reflux symptoms

The two classic symptoms are:[1][3]

• Heartburn: a burning feeling in the middle of the chest, behind the breastbone, which may rise towards the throat.
• Regurgitation: stomach contents coming back up into the throat or mouth, often with a sour or bitter taste.

Symptoms are often worse after eating, when lying down and when bending over.[1] Not everyone with GERD has heartburn. Other symptoms can include:[1][3]

• chest pain
• nausea, bloating or burping
• difficulty swallowing, or pain when swallowing
• a cough or hiccups that keep coming back
• a hoarse voice or bad breath.

Pain in the upper right tummy after a fatty meal may be caused by gallstones rather than reflux.

When reflux affects the throat

Some people mainly notice throat or chest symptoms, such as a persistent cough, hoarseness, frequent throat clearing or a feeling of a lump in the throat, with little or no heartburn. This is sometimes called laryngopharyngeal or "silent" reflux. Because these symptoms have many possible causes, they are worth getting checked rather than assuming reflux is to blame.[3]

Chest pain can be a heart problem. Reflux can cause chest pain, but so can a heart attack. If you have chest pain that is severe, spreads to your arm, neck, jaw or back, or comes with breathlessness, sweating or feeling faint, call 995 or go to the nearest Emergency Department.

What causes GERD?

Often there is no single cause. Factors that can make reflux more likely or worse include:[1][3]

• being overweight
• smoking, and drinking alcohol
• certain foods and drinks, such as coffee, chocolate, tomatoes, and fatty or spicy food
• large meals, or eating close to bedtime
• pregnancy
• stress and anxiety
• a hiatus hernia, where part of the stomach moves up into the chest[4]
• some medicines, including anti-inflammatory painkillers such as ibuprofen, some blood pressure medicines, certain asthma medicines and some sedatives.[3]

Don't stop a prescribed medicine on your own because you think it is causing reflux. Talk to the doctor who prescribed it first.[1]

GERD and liver health

Being overweight is linked to reflux and also to fatty liver disease, so the two conditions sometimes occur together. If you have GERD and are concerned about your liver, your doctor can look at both. Our article on the signs of liver disease explains what liver problems can look like.

When to see a doctor about heartburn

See a doctor if:[1][3]

• lifestyle changes and pharmacy medicines aren't helping
• you have heartburn on most days
• you keep needing antacids or other reflux medicines to control symptoms.

Seek medical advice promptly if heartburn or reflux comes with any of the following, as these can point to a complication or another condition:[1][3]

• food getting stuck, or difficulty or pain when swallowing
• frequent vomiting
• losing weight without trying, or loss of appetite
• vomit that contains blood or looks like coffee grounds
• black, tarry stools.

For black stools or other signs of bleeding, see our article on blood in stool.

How GERD is diagnosed

In many people, doctors diagnose GERD from the symptoms and medical history alone and start treatment without tests.[5] Tests are more likely to be suggested if symptoms don't improve with treatment, if there are warning signs, or if another condition needs to be ruled out.[5][6]

Gastroscopy (upper GI endoscopy)

A gastroscopy uses a thin, flexible tube with a camera to look at the lining of the oesophagus, stomach and the first part of the small intestine. Small tissue samples (biopsies) can be taken if needed.[5] It can show inflammation of the oesophagus (oesophagitis), narrowing, ulcers and Barrett's oesophagus, and can help rule out other causes of symptoms.[5][7]

If you're unsure how this differs from a bowel examination, see gastroscopy vs colonoscopy. Information on the endoscopy services at the clinic is on our Colonoscopy and Gastroscopy page.

Oesophageal pH monitoring

pH monitoring measures how often stomach acid comes up into the oesophagus. It is done either with a thin tube passed through the nose or with a small wireless capsule attached to the lining of the oesophagus. While it is in place, you record meals, sleep and symptoms so your doctor can see how they relate to reflux.[5][8] It is used to confirm GERD when the diagnosis is uncertain, or to check whether treatment is working.[5]

Other tests

Oesophageal manometry measures the pressure and muscle movement in the oesophagus when you swallow. It checks whether the oesophagus and the lower oesophageal sphincter are contracting and relaxing properly, and may be used when swallowing problems need to be looked into after other tests haven't found a cause.[9] If your doctor thinks H. pylori infection could be contributing to indigestion-type symptoms, they may suggest testing for it; our guide to the H. pylori breath test explains how that works.

Your doctor will explain what any recommended test involves and how to prepare. If you have questions before your appointment, you can send them through our contact form.

GERD treatment options

The aims of treatment are to relieve symptoms, let any inflammation of the oesophagus heal and lower the chance of complications.[2][6] Treatment is tailored to the person, and many people need a combination of approaches.

1. Lifestyle changes

These can reduce symptoms for many people:[1][6]

• eat smaller, more frequent meals
• avoid eating close to bedtime
• notice which foods and drinks trigger your symptoms and cut back on them
• lose weight if you're overweight
• stop smoking and cut down on alcohol
• avoid clothes that are tight around the waist
• raise the head of your bed with blocks or a wedge, so your chest and head are above your waist. Extra pillows alone can bend you at the waist and make things worse.[1]

2. Medicines

• Antacids and alginates can ease mild symptoms in the short term. They don't heal the oesophagus and are not meant for regular long-term use without medical advice.[1][3]
• H2 blockers reduce the amount of acid the stomach makes.[3]
• Proton pump inhibitors (PPIs), such as omeprazole, reduce stomach acid more strongly. They can relieve symptoms and help heal the oesophageal lining in most people with GERD.[3][6]

PPIs are generally well tolerated, but like all medicines they can have side effects, and research into high-dose or long-term use is ongoing. Your doctor will talk through the benefits and risks and review whether you still need them.[3][6]

3. Surgery and endoscopic procedures

Surgery may be considered if symptoms don't improve with lifestyle changes and medicines, or if someone doesn't want to take reflux medicines long term. The most common operation is fundoplication, in which the top of the stomach is wrapped around the lower oesophagus to strengthen the barrier against reflux. It is usually done by keyhole (laparoscopic) surgery.[3][6] Surgery carries a higher chance of complications than medicines, so it is a decision to make carefully with your doctor and, where needed, a surgeon.[3]

Possible complications of untreated GERD

Without treatment, GERD can sometimes lead to complications over time, such as:[2][7]

• oesophagitis: inflammation of the oesophagus, which can cause ulcers and bleeding
• stricture: narrowing of the oesophagus, which can make swallowing difficult
• Barrett's oesophagus: a change in the cells lining the oesophagus. People with Barrett's oesophagus have a higher risk of oesophageal cancer, although most never develop it.[7]

This is one reason ongoing or troublesome reflux is worth discussing with a doctor rather than treating on your own indefinitely.

Frequently asked questions

What is the difference between acid reflux and GERD?

Acid reflux is stomach contents flowing back into the oesophagus, which many people have occasionally. GERD is the term used when reflux happens often or causes troublesome symptoms or complications.[1][2]

What are the most common acid reflux symptoms?

Heartburn (a burning feeling in the middle of the chest) and regurgitation (a sour or bitter taste as stomach contents come up) are the most common. Some people instead have a cough, hoarseness, nausea or trouble swallowing.[1][3]

Do I need a gastroscopy for heartburn?

Not always. Many people are diagnosed and treated based on their symptoms. A gastroscopy may be advised if you have warning signs such as difficulty swallowing, weight loss or bleeding, if symptoms don't improve with treatment, or to check for complications.[5][6]

What is pH monitoring used for?

Oesophageal pH monitoring measures how often acid comes up into the oesophagus. It helps confirm GERD when the diagnosis is unclear, or check whether treatment is working.[5][8]

What does GERD treatment in Singapore usually involve?

Treatment generally follows international guidance: lifestyle changes, medicines that reduce stomach acid such as PPIs, and, for selected people, surgery such as fundoplication. Your doctor will recommend an approach based on your symptoms and test results.[3][6] You can ask about this at your consultation or send a question through our contact form.

Can GERD go away on its own?

Occasional reflux often settles with lifestyle changes. GERD tends to be a longer-term condition that may need ongoing management, so speak to a doctor if symptoms keep coming back.[1][3]
