Understanding Acid Reflux & Heartburn
Heartburn, a common symptom of GERD, occurs when stomach acid frequently flows back into the oesophagus, leading to irritation and potential complications. As a GERD specialist in Singapore, Dr. Prem Thurairajah provides comprehensive evaluation and treatment for heartburn and related symptoms.
Common Symptoms
When to See a GERD Specialist in Singapore
Gastro-oesophageal reflux disease (GERD) is a common condition that occurs when stomach acid repeatedly flows back into the oesophagus (food pipe), causing irritation and symptoms such as heartburn or regurgitation. While occasional reflux can happen in many people, persistent or worsening symptoms may require specialist evaluation.
Heartburn, Acid Reflux and GERD Are Not the Same
Many people use the terms “heartburn”, “acid reflux”, and “GERD” interchangeably, but they are slightly different.
- Acid reflux refers to the backflow of stomach contents into the oesophagus.
- Heartburn is the burning sensation in the chest that reflux can cause.
- GERD is a more chronic condition where reflux occurs frequently and may lead to inflammation or complications over time.
Occasional reflux after a heavy or spicy meal is common. However, symptoms that occur regularly, disturb sleep, or affect daily life may suggest GERD rather than simple indigestion.
Signs You Should Book a Specialist Review
You should consider seeing a gastroenterologist if you experience:
- Frequent heartburn or reflux symptoms occurring several times a week
- Symptoms persisting despite lifestyle changes or over-the-counter medication
- Difficulty swallowing or food feeling stuck
- Persistent nausea, bloating, or upper abdominal discomfort
- Chronic cough, throat irritation, hoarseness, or worsening asthma symptoms linked to reflux
- Unexplained weight loss, reduced appetite, or anaemia
- Recurrent vomiting or vomiting blood
- Black stools or evidence of gastrointestinal bleeding
People above the age of 40–50 with new-onset reflux symptoms, especially in Asian populations where gastric cancer risk remains relevant, may also benefit from further assessment.
What a GERD Assessment May Involve
A specialist consultation usually begins with a detailed review of your symptoms, diet, medications, and lifestyle factors.
Depending on your symptoms and risk profile, further investigations may include:
- Gastroscopy (OGD) to examine the oesophagus, stomach, and upper small intestine
- Biopsies to assess for inflammation, Barrett’s oesophagus, or other conditions
- Testing for Helicobacter pylori infection where appropriate
- Oesophageal pH monitoring to assess acid exposure
- Oesophageal manometry to evaluate swallowing function and oesophageal muscle activity
Not every patient requires extensive testing. In many cases, assessment is tailored according to symptom severity, duration, and response to treatment.
When Reflux May Need More Than Medication
Lifestyle changes and acid-suppressing medication are often effective for mild reflux symptoms. These may include:
- Weight management
- Avoiding late-night meals
- Reducing alcohol, caffeine, or trigger foods
- Elevating the head during sleep
- Smoking cessation
However, some patients continue to have symptoms despite medication, while others may develop complications such as oesophagitis, strictures, or Barrett’s oesophagus.
In these situations, a specialist review is important to:
- Confirm the diagnosis
- Exclude other upper gastrointestinal conditions
- Optimise long-term treatment
- Assess whether advanced therapies or anti-reflux procedures may be appropriate
Early assessment can help prevent complications and improve long-term symptom control.
Risk Factors
Understanding the risk factors for heartburn can help you make lifestyle changes to reduce your symptoms and prevent complications.

Obesity
Excess weight increases abdominal pressure, pushing stomach contents into the oesophagus.

Hiatal Hernia
Part of the stomach pushes through the diaphragm, weakening the lower oesophageal sphincter.
Smoking
Tobacco relaxes the lower oesophageal sphincter and reduces saliva production.
Large or Late Meals
Eating large portions or late at night increases pressure on the stomach and reflux risk.
Trigger Foods
Fatty, fried, spicy foods, citrus, tomatoes, and chocolate can trigger symptoms.
Alcohol & Caffeine
Both relax the lower oesophageal sphincter and increase acid production.
Potential Complications
Untreated acid reflux can lead to serious complications affecting the oesophagus. Early diagnosis and treatment can prevent these conditions.

Oesophagitis
Inflammation of the oesophagus causing pain, bleeding, and ulceration from repeated acid exposure.

Oesophageal Stricture
Narrowing of the oesophagus due to scar tissue formation, causing difficulty swallowing.

Barrett's Oesophagus
Pre-cancerous changes in the oesophageal lining requiring regular surveillance endoscopy.

Oesophageal Cancer
Long-standing Barrett's oesophagus increases the risk of developing adenocarcinoma.
Investigations for Heartburn
Accurate diagnosis of heartburn often requires specialised tests to assess the extent of acid reflux and any damage to the oesophagus.

OGD (Oesophago-Gastro-Duodenoscopy)
Also known as gastroscopy, this procedure uses a thin, flexible camera (endoscope) to directly visualise the oesophagus, stomach, and duodenum.
- Detects oesophagitis (inflammation) and erosions
- Identifies Barrett's oesophagus (pre-cancerous changes)
- Allows biopsies for further analysis
- Rules out other conditions like ulcers or cancer

Bravo Capsule pH Monitoring
A wireless, catheter-free pH monitoring system that measures acid exposure in the oesophagus over 48-96 hours for accurate heartburn diagnosis.
- Small capsule attached to the oesophageal wall
- Transmits pH data wirelessly to a recorder
- More comfortable than traditional catheter-based tests
- Primary clinical modality for quantifying acid reflux episodes
Heartburn Treatment
Treatment for heartburn is tailored to the severity of symptoms and presence of complications:
Lifestyle Modifications
- Maintain a healthy weight
- Avoid trigger foods and late meals
- Elevate the head of your bed
- Stop smoking
- Limit alcohol and caffeine
Medical Treatment
- Antacids for occasional symptoms
- H2 blockers (e.g., famotidine)
- Proton pump inhibitors (PPIs)
- Prokinetic agents when needed
- Endoscopic or surgical options for severe cases
