Most people treat GERD as simple acidity for years — and pay the price later. Understanding the difference between temporary acidity and chronic GERD can prevent serious complications including oesophageal cancer.
The Core Distinction
Acidity is a symptom — a temporary burning sensation caused by excess stomach acid. It can be triggered by a heavy meal, spicy food, alcohol, or stress, and typically resolves on its own or with a basic antacid.
GERD is a chronic disease — Gastro-Oesophageal Reflux Disease occurs when the lower oesophageal sphincter (LOS), the muscular valve between the oesophagus and stomach, is weak or dysfunctional. This allows stomach acid to repeatedly flow back into the oesophagus, causing persistent inflammation and, over time, structural damage.
How Common Is GERD in India?
GERD affects 7–18% of the Indian population, with significantly higher rates in urban areas due to dietary habits, sedentary lifestyles, obesity, and stress. Many patients manage symptoms with over-the-counter antacids for years without ever receiving a formal diagnosis.
Recognising GERD: Beyond the Typical Symptoms
The classic symptoms of GERD — heartburn and acid regurgitation — are well known. But GERD also presents with atypical symptoms that are frequently misattributed to other conditions:
- Chronic cough (especially at night)
- Persistent hoarseness or voice change
- Frequent throat clearing
- Dental erosion
- Chest pain (mimicking cardiac symptoms)
- Worsening asthma
- Globus sensation (lump-in-throat feeling)
These atypical presentations often lead to delays in diagnosis and inappropriate treatment.
Why Self-Treating with Antacids Is a Problem
Antacids neutralise stomach acid temporarily. They relieve the symptom but do not address the underlying LOS dysfunction that allows acid to reflux. Continuous self-treatment with antacids:
- Masks symptoms that could indicate worsening disease
- Delays diagnosis of Barrett’s oesophagus — a precancerous condition
- Allows ongoing mucosal damage to accumulate silently
- Creates false reassurance that the problem is minor
Dangerous Complications of Untreated GERD
Prolonged, untreated GERD can lead to:
- Oesophagitis: Inflammation and ulceration of the oesophageal lining
- Oesophageal strictures: Narrowing due to repeated scarring, causing difficulty swallowing
- Barrett’s Oesophagus: Abnormal cell changes in the oesophageal lining — a direct precursor to oesophageal adenocarcinoma
- Oesophageal adenocarcinoma: A cancer with poor prognosis when diagnosed late
How Is GERD Treated?
Management follows a structured three-step approach:
Step 1: Lifestyle Modifications
- Eat smaller, more frequent meals
- Avoid eating within 3 hours of lying down
- Elevate the head of the bed by 15–20 cm
- Lose weight if overweight — even modest weight loss reduces reflux episodes significantly
- Avoid trigger foods: fatty meals, citrus, caffeine, carbonated drinks, alcohol, chocolate, mint
- Quit smoking
Step 2: Medical Treatment
Proton Pump Inhibitors (PPIs) are the mainstay of GERD treatment, reducing acid production. They must be taken correctly — typically 30–45 minutes before meals — for optimal effect. H2 blockers can be used for milder cases or on-demand symptom relief.
Step 3: Endoscopic or Surgical Options
For patients who do not respond to medication, or who prefer not to take long-term medication, options include anti-reflux surgery (laparoscopic fundoplication) or newer endoscopic procedures such as radiofrequency ablation of the LOS.
Red Flags That Require Immediate Specialist Review
- Symptoms persisting beyond 3–6 months despite antacids
- Nighttime symptoms disrupting sleep
- Difficulty or pain on swallowing (dysphagia)
- Unexplained weight loss
- Blood in vomit or black stools
- Onset after age 50 without prior GI history
Key Takeaway
Acidity and GERD are not the same condition. If you have been managing recurring heartburn with antacids for months or years, you may be treating a symptom while a chronic disease progresses underneath. A gastroenterology consultation — and in some cases an upper GI endoscopy — can accurately diagnose your condition and prevent serious long-term complications.
