Gastroesophageal reflux disease (GERD) affects approximately 20% of American adults — making it one of the most prevalent gastrointestinal conditions in the country. Heartburn, the hallmark symptom, is so common that over 60 million Americans experience it at least once monthly. Despite its familiarity, GERD is frequently undertreated, and its long-term consequences — including oesophageal damage and, rarely, Barrett's oesophagus and oesophageal adenocarcinoma — make proper management important.
What Is GERD?
GERD occurs when stomach acid or, less commonly, bile refluxes into the oesophagus through a weakened lower oesophageal sphincter (LES) — the muscular valve separating the stomach from the oesophagus. Unlike the stomach, the oesophageal lining lacks acid-protective mucosa, so repeated acid exposure causes inflammation (oesophagitis), erosions, and in some patients, metaplastic changes (Barrett's oesophagus).
Symptoms Beyond Heartburn
Classic GERD produces a burning sensation behind the sternum, worse after meals, bending forward, lying flat, or eating acidic, fatty, or spicy foods. But GERD can also manifest as: regurgitation (sour or bitter taste in the mouth), chronic cough (acid reaching the larynx stimulates the cough reflex), hoarseness (laryngopharyngeal reflux), dental erosion, difficulty swallowing, globus sensation (lump in the throat), and atypical chest pain that closely mimics cardiac pain. These "silent" or atypical presentations are frequently misattributed to other conditions.
Lifestyle Modifications — The Foundation
- Elevate the head of the bed 6–8 inches: Gravity reduces nighttime acid exposure; using extra pillows is less effective as it can worsen abdominal pressure.
- Avoid trigger foods: Fatty meals, chocolate, mint, onions, garlic, citrus, tomatoes, caffeine, and alcohol all reduce LES pressure or increase acid production.
- Don't eat 2–3 hours before lying down
- Lose weight: Abdominal fat increases intragastric pressure. Even modest weight loss (10%) significantly reduces GERD symptoms.
- Quit smoking: Nicotine relaxes the LES directly.
- Eat smaller, more frequent meals: Large meals distend the stomach and increase reflux pressure.
Medications
Proton pump inhibitors (PPIs) — omeprazole, pantoprazole, esomeprazole, lansoprazole — are the most effective acid suppressants available, reducing gastric acid production by 80–95% when taken 30–60 minutes before the first meal of the day. They heal oesophagitis and control GERD symptoms in the majority of patients. Long-term use carries modest risks including reduced magnesium and vitamin B12 absorption, and a small increased risk of Clostridium difficile infection. Use the lowest effective dose for the shortest necessary duration. H2 blockers (famotidine, ranitidine) are less potent but faster-acting; useful for on-demand symptom relief. Antacids provide immediate but short-lived symptom relief.
When to Seek Evaluation
See a gastroenterologist for: symptoms despite 4–8 weeks of PPI therapy, difficulty or pain swallowing, unintentional weight loss, vomiting blood or black stools, anaemia, or new GERD symptoms in someone over 50 (to rule out Barrett's and malignancy). Upper endoscopy (gastroscopy) directly visualises the oesophageal lining and is the definitive diagnostic and surveillance tool.
