Introduction
Gastroesophageal reflux disease (GERD) is a chronic condition in which stomach acid or bile repeatedly flows back into the esophagus, irritating its lining. It happens when the lower esophageal sphincter (LES) — the muscle that normally keeps stomach contents from moving upward — weakens or relaxes at the wrong times. GERD is not a single, uniform condition: it ranges from mild, infrequent reflux that responds to simple dietary changes, to erosive esophagitis and long-standing disease that can lead to Barrett's esophagus if left unmanaged. At KAGE (KIMS Advanced Gastroenterology & Endoscopy), GERD is diagnosed and staged properly before treatment is chosen — not treated as one-size-fits-all — using both standard medical management and advanced endoscopic procedures for patients who need more than medication alone.
Types of GERD
- Non-erosive reflux disease (NERD) — typical GERD symptoms with no visible damage to the esophagus on endoscopy; the most common presentation
- Erosive esophagitis — visible inflammation or breaks in the esophageal lining, graded by severity (commonly using the Los Angeles Classification, Grade A to D)
- Barrett's esophagus — a longer-term change in the esophageal lining caused by chronic acid exposure, requiring its own monitoring and treatment pathway
Symptoms of GERD
Typical symptoms:
- Heartburn — a burning sensation in the chest, often after eating or when lying down
- Regurgitation of food or sour liquid
- Chest discomfort, sometimes mistaken for a heart problem
Atypical symptoms — easy to miss as GERD, especially when heartburn isn't prominent:
- Chronic cough or throat clearing
- Hoarseness or voice changes
- A sensation of a lump in the throat
- Worsening of asthma symptoms
- Dental enamel erosion
- Disrupted sleep from nighttime reflux
What causes GERD
- A weakened or improperly relaxing lower esophageal sphincter
- Hiatal hernia — a common contributing cause, and the reason reflux and hernia are often assessed together
- Obesity and excess abdominal pressure
- Pregnancy
- Smoking, alcohol, caffeine, and certain foods
- Delayed stomach emptying
How GERD is diagnosed
- Upper GI endoscopy — examines the esophagus directly, checks for erosive damage or Barrett's changes, and grades severity
- 24-hour pH monitoring — measures acid exposure in the esophagus over a full day, useful when symptoms are present but endoscopy looks normal
- Esophageal manometry — measures muscle function in the esophagus and LES, and is essential before considering surgery or endoscopic therapy to rule out a motility disorder like achalasia
- Barium swallow study, in select cases
GERD treatment: a staged approach
KAGE matches treatment intensity to how a patient actually responds, rather than jumping straight to a procedure:
- Step 1 — Lifestyle and dietary changes: weight management, meal timing, elevating the head of the bed, avoiding trigger foods
- Step 2 — Medication: a trial of proton pump inhibitors (PPIs) or H2 blockers, typically over 4–8 weeks, to see how well symptoms respond
- Step 3 — Re-evaluation if symptoms persist: endoscopy, pH monitoring, and manometry to confirm the diagnosis and rule out other causes before considering a procedure
- Step 5 — Surgical fundoplication: reserved for select complex cases, such as a large hiatal hernia, where endoscopic treatment isn't the right fit
Possible complications if left untreated
Long-standing, untreated GERD can lead to esophagitis, esophageal stricture (narrowing that causes swallowing difficulty), or Barrett's esophagus — a precancerous change in the esophageal lining that requires its own monitoring and treatment.
Care team for GERD at KAGE
GERD at KAGE is managed by our gastroenterologists experienced in both medical management and advanced endoscopic anti-reflux procedures. If reflux has persisted despite medication, book a consultation to have your symptoms, previous treatment, and test results reviewed.
Frequently asked questions
Both are endoscopic anti-reflux procedures performed without external incisions. The right choice depends on individual anatomy and disease severity, which your gastroenterologist will assess during consultation.
Yes, a hiatal hernia can weaken the lower esophageal sphincter and is a common contributing cause of GERD.
Chest pain should never be assumed to be reflux. Cardiac causes must be ruled out first, especially if the pain is severe, radiates to the arm or jaw, or comes with breathlessness or sweating — seek emergency care immediately in that case.
Both are outpatient or short-stay endoscopic procedures with no external incisions; most patients return to normal activity within a few days, faster than with surgical fundoplication.
Mild, occasional reflux can improve with diet and lifestyle changes alone. Persistent GERD usually needs ongoing management, since the underlying sphincter weakness doesn't typically resolve by itself.
Diagnostic evaluation and medication are generally covered under standard health insurance; coverage for endoscopic procedures like ARMA and GERDx depends on your specific policy — our team can help verify coverage and explain costs during consultation.
Yes. Pediatric GERD is managed separately — see KAGE's pediatric gastroenterology team for children's reflux care.
