GERD, or Gastro-oesophageal Reflux Disease, is often dismissed as simple heartburn, but it’s much more than that. While it’s a common issue, many don’t realise that GERD can affect more than just the stomach; it can significantly impact your daily life. Surprisingly, GERD one of the most misunderstood conditions, and understanding it better could make all the difference in managing it. Let’s take a closer look at what GERD really is and how small changes can improve your wellbeing.
The underlying causes of GERD: Why are so many people affected?
GERD is more than just an inconvenience. It’s a chronic condition where stomach acid flows back into the oesophagus, causing pain, irritation, and potential damage. For many, symptoms like chest pain, heartburn, and a sour taste in the mouth, are daily struggles that affect everything from work productivity to relationships. And yet, despite its increasing prevalence, GERD is often downplayed in health discussions.

Diet: From fast food to large portions
While many people associate GERD with spicy food, processed, high-fat foods, oversized portions, and late-night eating are increasingly problematic. It’s not just about what you eat, but also when and how much you eat. Overloading the stomach with high-fat meals can stretch it, forcing acid into the oesophagus. The increased consumption of fast food, sugary drinks, and processed snacks has worsened GERD rates globally.
A diet high in fat and sugar increases inflammation, slows digestion, and makes the lower oesophageal sphincter (LES) more likely to fail. The body simply isn't built to handle the overload of fast food, sugary beverages, and rich processed meals that are prevalent in modern diets.

Obesity: A major risk factor for GERD
Obesity is closely linked to GERD. Extra fat, especially around the abdomen, places pressure on the stomach, forcing acid to back up into the oesophagus. This is worsened by the fact that obesity can weaken the lower oesophageal sphincter (LES), leading to more frequent reflux. Research consistently shows that obesity-related GERD is particularly common in Western countries, where sedentary lifestyles and poor eating habits prevail.
Several studies have confirmed the connection between BMI and GERD. For instance, a study published in The American Journal of Gastroenterology found that individuals with a higher body mass index (BMI) have a significantly higher risk of developing GERD compared to those with a normal BMI. Another study in Obesity Research confirmed that abdominal obesity is a key factor in increasing the likelihood of reflux symptoms, as excess fat around the abdomen exerts pressure on the stomach. Additionally, recent research in Gastroenterology has demonstrated that weight loss can lead to a reduction in GERD symptoms and improve overall quality of life for patients with GERD.

Stress: A hidden trigger for GERD
Many don’t realise that stress, beyond just diet, can play a major role in triggering and worsening GERD. Chronic stress leads to the overproduction of stomach acid while also slowing digestion. This imbalance increases the likelihood of acid reflux. Work-related stress, financial anxiety, or emotional strain can cause the body to produce more stomach acid, aggravating GERD symptoms.
Recent research supports this, revealing that individuals under high stress report a significant increase in GERD symptoms. This indicates that stress management is just as critical as dietary adjustments when it comes to managing GERD.

Sedentary lifestyles: A growing problem
As more people spend long hours sitting at desks or in front of screens, physical activity has decreased significantly, contributing to the rise in GERD. Prolonged sitting and lack of movement can impair digestion and put pressure on the abdomen, leading to more frequent episodes of acid reflux.
What’s alarming is that many people don’t realise how inactivity can be as damaging to digestion as an unhealthy diet. Simple movements, like walking after meals or standing periodically, can improve digestion and reduce GERD symptoms.

Dr Tan notes that heartburn, a common symptom of GERD, can sometimes signal a more serious problem. "Acid reflux into the oesophagus can sometimes cause significant inflammation, damage, and scarring," Dr. Tan explains. "Most often, though, the acid causes minimal inflammation or even no visible damage, just symptoms."
The dangers of untreated acid reflux include:
- Erosions or ulcers: In severe cases, acid can cause ulcers at the lower end of the oesophagus. If deep enough, these ulcers can damage blood vessels, leading to bleeding.
- Oesophageal stricture: Over time, this damage can cause scarring and narrowing of the oesophagus, making swallowing difficult. Food may get stuck (dysphagia) or swallowing can become painful (odynophagia).
- Barrett’s oesophagus: In some cases, the lower oesophagus lining becomes scarred, causing a cellular change known as Barrett’s Oesophagus. This condition increases the risk of oesophageal cancer.
GERD’s toll on daily life
While the statistics on GERD are alarming, the personal impact is often even more troubling. What begins as occasional heartburn can quickly escalate into a chronic condition, affecting more than just physical health. But the good news is that GERD doesn’t have to control your life. With the right lifestyle adjustments and an understanding of triggers, you can manage this condition effectively. The key is recognising that small, consistent changes can make a world of difference.
For many, GERD begins as mild discomfort after a heavy meal, but over time, it becomes a daily struggle. What was once a rare occurrence transforms into frequent reflux episodes, disrupting sleep, altering eating habits, and impacting work performance. The exhaustion caused by persistent symptoms, combined with an inability to sleep or focus, can take a serious toll.
This is not an uncommon experience. Many GERD sufferers face sleep disruption, heightened fatigue, and stress from constant discomfort. Yet these impacts are often overlooked in medical discussions. GERD is often dismissed as a condition that can be managed with over-the-counter medications, but for those living with it, the challenges are much more significant.

Dr Tan provide an overview of the diagnostic process for GERD. “To get an accurate diagnosis, your doctor will take a detailed history of your symptoms and perform a clinical examination,” Dr Tan explains. “One common test is gastroscopy. This involves a long, thin instrument called a gastroscope inserted through the mouth into the oesophagus, stomach, and first part of the small intestine (the duodenum). During this test, the doctor can assess the degree of damage caused by acid reflux and take biopsies if needed.”
If damage is visible, it can be classified into Los Angeles Grades A-D, depending on the severity of inflammation. If no inflammation is seen but symptoms are typical, it may be diagnosed as Non-erosive reflux disease.
For further confirmation, tests like oesophageal pH monitoring (to measure acidity) or manometry (to check pressure in the oesophagus) might be recommended. Another option is pH-impedance monitoring, which detects fluid shifts in the oesophagus.
Certain medications, such as those for high blood pressure, asthma, or depression, can relax the valve between the oesophagus and stomach, potentially leading to heartburn. Always tell your doctor about all the medications you're taking for the most accurate diagnosis.
GERD and its link to respiratory conditions
GERD isn’t just a digestive issue; untreated GERD can cause significant respiratory complications, including asthma, chronic cough, and laryngitis. This occurs when acid reflux from the stomach reaches the lungs, triggering inflammation and worsening respiratory symptoms.
A study published in The Journal of Clinical Gastroenterology found that nearly 40% of asthma patients also had GERD. This connection is still being explored, but it’s becoming clear that acid reflux can exacerbate asthma symptoms by causing inflammation in the airways or by direct aspiration of gastric contents into the lungs, leading to bronchospasm.
Additionally, chronic cough and laryngitis are common manifestations of GERD that are often misdiagnosed or overlooked. These symptoms occur because the acid in the oesophagus can irritate the throat and vocal cords, resulting in a persistent cough or hoarseness.
As research continues to investigate this link, it’s important to recognise that GERD can affect more than just the digestive system. Treating GERD appropriately may help improve respiratory symptoms, particularly in patients with asthma or chronic cough that is not fully controlled by asthma medications alone.
EXPERT TIP
For mild symptoms, a GP might offer a trial of medication to reduce stomach acid, such as antacids, H2-receptor antagonists (H2RA) or proton pump inhibitors (PPIs). If the medication works and symptoms are relieved, it’s a good sign that the treatment is effective. However, it’s important to monitor whether the symptoms return. If they keep recurring, worsen, or if alarm symptoms like difficulty swallowing or persistent chest pain arise, it’s no longer advisable to continue relying on medication alone. In such cases, patients should undergo further tests with a gastroenterologist to explore the underlying cause.
Lifestyle changes that can make a real difference
As doctors and researchers continue to explore GERD, one thing is clear: lifestyle changes can have a profound impact. Here’s how small adjustments can make a big difference:
|
Smaller, frequent meals
Rather than loading up on large meals that overwhelm your digestive system, try eating smaller meals throughout the day. This reduces the chances of triggering acid reflux and allows your body to process food more efficiently. Eating slowly and mindfully also helps reduce the risk of overeating, which can lead to GERD flare-ups.
|
|
Avoid trigger foods
You may not realise that your favourite foods could be contributing to your GERD symptoms. Start by identifying and avoiding the foods that commonly trigger reflux. While this list may vary for everyone, common culprits include fatty foods, fried foods, caffeine, alcohol, chocolate, and citrus fruits. Keep a food journal to track what you eat and how it makes you feel. This will help you identify patterns and pinpoint your personal triggers.
|
|
Lose excess weight
If you’re carrying extra weight, losing even a small amount can help alleviate GERD symptoms. Research shows that weight loss can reduce the pressure on the stomach, thus reducing the likelihood of acid reflux. Regular physical activity, such as walking, swimming, or cycling, can help manage weight and improve digestion.
|
|
Sleep smart
How you sleep can significantly affect GERD symptoms. Try sleeping with your head elevated, either by using a wedge pillow or raising the head of your bed. This position helps prevent stomach acid from flowing back into the oesophagus while you sleep. Additionally, try to avoid eating late at night and give yourself at least 3 hours between your last meal and bedtime.
|
|
Manage stress
Chronic stress can wreak havoc on your digestive system. Incorporating stress management techniques into your daily routine, such as meditation, deep breathing exercises, or yoga, can help reduce GERD symptoms. Even taking short breaks throughout your day to relax can make a difference. Remember, managing stress is not just about avoiding it; it’s about learning how to cope with it effectively.
|
|
Quit smoking
Smoking weakens the LES and impairs the body’s ability to handle stomach acid. If you smoke, quitting could be one of the most important steps you take in managing GERD. It may be challenging, but with the right support, quitting smoking will not only improve your GERD symptoms but also your overall health.

Dr Tan outlines the five main goals of GERD treatment: relieving symptoms, healing any oesophageal damage, restoring quality of life, preventing symptom relapse, and avoiding complications.
The most common treatments include medications that either neutralise stomach acid (antacids) or reduce acid production. H2RAs, PPIs and Potassium Competitive Acid Blockers (K-CAB) are typically prescribed, depending on the severity of symptoms and the extent of oesophageal damage. In general, if there are erosions, only stronger medicines such as PPIs and K-CABs will be effective in healing the erosions.
Typically, treatment starts with a course of medication, which is gradually reduced to the smallest effective dose that keeps symptoms under control. When possible, patients are advised to use medications only "on demand," meaning they take them when symptoms occur and stop once they’re relieved. However, some individuals may need to continue with maintenance medication, especially if there are significant erosions in the oesophagus.
In rare cases, surgery may be recommended if medications do not provide relief. This procedure tightens the valve between the oesophagus and the stomach to prevent acid reflux. There are also newer, less invasive surgical methods using special endoscopes, which are becoming increasingly available as alternatives to conventional surgery. However, surgery is reserved for the most challenging cases, as all surgical procedures come with inherent risks. For most patients, medication is the preferred method of treatment.
GERD is not just a common inconvenience, but a growing global epidemic, fuelled by modern lifestyle habits. While lifestyle changes can significantly improve GERD management, the real issue is a lack of awareness. Many people don’t realise that GERD is a chronic condition that can lead to serious complications if left untreated.
As the number of GERD sufferers continues to climb, it’s vital for society, healthcare providers, and individuals to take this condition seriously. Simple changes in diet, stress management, and physical activity can make a huge difference, yet this requires greater public education and support to make lasting improvements.
If you’re one of affected by GERD, remember: relief is within reach. Understanding your condition and taking action can lead to a better quality of life.
