What is the difference between acid reflux and GERD?
Acid reflux is the occasional backflow of stomach acid into the oesophagus, causing heartburn. GERD (Gastroesophageal Reflux Disease) is the chronic, medically diagnosed form — defined as acid reflux occurring at least twice a week and causing measurable oesophageal damage or persistent symptoms. GERD is more serious and requires structured medical management.
S.L. Raheja Hospital in Mumbai offers specialised Gastro-Intestinal Science services to evaluate, diagnose, and manage both acid reflux and GERD through evidence-based care at its Mahim West facility.
Tip: Think of acid reflux as a symptom and GERD as the underlying condition. Not everyone with acid reflux has GERD, but everyone with GERD experiences acid reflux.
| Feature | Acid Reflux | GERD |
|---|---|---|
| Frequency | Occasional | 2+ times per week, chronic |
| Diagnosis | Symptom-based | Clinical / endoscopic diagnosis |
| Oesophageal damage | Usually absent | May be present |
| Treatment needed | Lifestyle changes, OTC relief | Prescription medication, possible procedure |
What are the symptoms of GERD and acid reflux?
Both conditions share overlapping symptoms, but GERD symptoms tend to be more frequent, more severe, and may include complications not seen with occasional acid reflux.
Common symptoms of acid reflux:
- Burning sensation in the chest (heartburn), typically after eating
- Sour or bitter taste at the back of the throat
- Regurgitation of food or liquid
- Mild bloating or belching
The 8 key symptoms of GERD:
- Persistent heartburn occurring two or more times per week
- Chronic regurgitation of acid or undigested food
- Difficulty swallowing (dysphagia)
- Sensation of a lump in the throat
- Chronic dry cough, especially at night
- Hoarseness or sore throat on waking
- Chest pain (non-cardiac in origin — see warning below)
- Disrupted sleep due to nocturnal reflux
Warning: Chest pain can be a symptom of GERD, but it can also indicate a cardiac event. If you experience sudden, severe chest pain — especially with shortness of breath, sweating, or pain radiating to the arm or jaw — seek emergency care immediately. Do not self-diagnose chest pain as reflux.
What causes acid reflux and GERD?
Both acid reflux and GERD occur when the lower oesophageal sphincter (LOS) — the muscular valve between the oesophagus and stomach — weakens or relaxes inappropriately, allowing stomach acid to flow upward.
Common causes and risk factors include:
- Hiatal hernia (part of the stomach pushes above the diaphragm)
- Obesity or excess abdominal weight increasing stomach pressure
- Pregnancy
- Smoking, which weakens the LOS
- Certain medications (NSAIDs, calcium channel blockers, antihistamines)
- Eating large meals or lying down shortly after eating
- High intake of fatty, fried, or spicy foods
- Excessive caffeine or alcohol consumption
Understanding the underlying cause is essential for choosing the right acid reflux treatment and preventing progression to GERD or its complications.
What foods trigger GERD, and what foods help?
Diet plays a significant role in managing both acid reflux and GERD. Certain foods relax the lower oesophageal sphincter or increase stomach acid production, worsening symptoms.
Foods to avoid with GERD:
- Spicy foods (chillies, hot sauces)
- Fatty or fried foods
- Citrus fruits and juices (oranges, lemons, tomatoes)
- Chocolate and peppermint
- Caffeinated drinks (coffee, tea, cola)
- Alcohol
- Carbonated beverages
- Onions and garlic
Foods that may help reduce GERD symptoms:
- Non-citrus fruits (bananas, melons, apples)
- Vegetables (broccoli, green beans, cauliflower)
- Whole grains (oatmeal, brown rice)
- Lean proteins (chicken, fish, tofu)
- Low-fat dairy or dairy alternatives
- Ginger (in moderate amounts)
Tip: Eating smaller, more frequent meals and avoiding food within 2–3 hours of bedtime can significantly reduce nocturnal reflux episodes.
What are the long-term treatment options for GERD?
GERD treatment is stepwise — starting with lifestyle changes and progressing to medication or procedures depending on severity. Acid reflux medicine is often the first line of management for chronic cases.
Lifestyle modifications:
- Elevating the head of the bed by 15–20 cm
- Losing excess weight
- Quitting smoking
- Avoiding trigger foods and large meals
- Not lying down within 2–3 hours of eating
Medications commonly used:
- Antacids — neutralise stomach acid for quick, short-term relief
- H2 blockers — reduce acid production (e.g., famotidine)
- Proton pump inhibitors (PPIs) — the most effective acid-suppressing medication for chronic GERD; taken under medical supervision
- Prokinetics — help the stomach empty faster, reducing reflux
Procedural options for refractory GERD:
- Endoscopic therapies to reinforce the lower oesophageal sphincter
- Laparoscopic fundoplication (surgical wrapping of the stomach around the oesophagus)
The gastroenterology team at S.L. Raheja Hospital, Mahim West, evaluates each patient individually to determine the most appropriate treatment pathway, including endoscopic assessment where indicated.

When should you see a gastroenterologist for acid reflux or GERD?
Occasional heartburn after a heavy meal is common and usually not a cause for concern. However, certain signs indicate that a clinical evaluation is necessary.
Consult a gastroenterologist if you experience:
- Heartburn or regurgitation occurring two or more times per week for more than 4 weeks
- Difficulty or pain when swallowing
- Unintentional weight loss
- Vomiting blood or passing black, tarry stools
- Chest pain (after ruling out a cardiac cause)
- Symptoms that do not improve with over-the-counter antacids after 2 weeks
- Chronic cough or hoarseness with no identified respiratory cause
- Worsening symptoms despite dietary changes
Untreated GERD can lead to complications including oesophagitis (inflammation of the oesophageal lining), Barrett's oesophagus (a precancerous change in oesophageal cells), and in rare cases, oesophageal cancer. Early evaluation significantly reduces these risks.
How does S.L. Raheja Hospital in Mumbai support patients with GERD?
S.L. Raheja Hospital in Mumbai provides structured gastroenterology care for patients with acid reflux and GERD at its Mahim West facility. The gastroenterology team conducts thorough clinical assessments, including endoscopic evaluation where appropriate, to confirm diagnosis and rule out complications such as Barrett's oesophagus.
Management plans are tailored to each patient and may include dietary counselling, prescription medication regimens, and — where conservative measures are insufficient — referral for minimally invasive procedures. Patients with co-existing conditions such as diabetes or hormonal disorders that may influence reflux are managed in a coordinated, multi-speciality approach.
