What Is GERD?
Gastroesophageal reflux disease (GERD) occurs when stomach acid repeatedly flows back into the esophagus, causing irritation, inflammation, and the characteristic symptoms of heartburn and regurgitation. The underlying mechanism involves dysfunction or transient relaxation of the lower esophageal sphincter (LES) — the muscular valve separating the stomach from the esophagus.
GERD affects approximately 20% of the US adult population and is one of the most common conditions managed in primary care. The American College of Gastroenterology (ACG) guidelines recognize that a clinical diagnosis based on typical symptoms — without endoscopy — is appropriate for most patients under 60 without alarm features.
your board-certified provider, follows ACG guidelines for GERD management, using a structured approach from lifestyle modification through escalating pharmacologic therapy when indicated.
Common GERD Symptoms
Heartburn — burning sensation behind the breastbone, often after eating or lying down
Acid regurgitation — sour or bitter taste in the mouth or throat
Chest discomfort (non-cardiac chest pain)
Chronic cough or throat clearing (laryngopharyngeal reflux)
Hoarseness, sore throat, or globus sensation (lump in throat)
Worsening at night or when bending/lying flat
Step-Up Treatment Approach
ACG guidelines recommend a step-up approach, beginning with lifestyle modification and progressing to pharmacologic therapy based on symptom severity and frequency.
Lifestyle Modifications (All Patients)
Elevate head of bed 6–8 inches. Avoid eating within 2–3 hours of bedtime. Weight loss if BMI >25. Eliminate or reduce trigger foods (fatty foods, caffeine, chocolate, citrus, tomato, alcohol, mint). Smaller, more frequent meals. Smoking cessation.
Antacids (Mild, Infrequent Symptoms)
Calcium carbonate (Tums), aluminum/magnesium hydroxide (Maalox, Mylanta). Rapid symptom relief but no mucosal healing. Appropriate for mild, infrequent heartburn (<2 episodes/week).
H2 Receptor Antagonists (Moderate Symptoms)
Famotidine (Pepcid) 20–40 mg BID is the current first-line H2 blocker (ranitidine/Zantac withdrawn from market due to NDMA contamination concerns). Effective for mild-moderate GERD; onset within 1–3 hours; useful for nocturnal symptoms.
Proton Pump Inhibitors — PPIs (Frequent or Erosive GERD)
PPIs are the most effective acid suppression therapy. First-line for erosive esophagitis and symptoms occurring ≥2 days/week. Take 30–60 minutes before the first meal of the day for optimal efficacy.
Omeprazole (Prilosec)
20–40 mg daily × 4–8 wks
Pantoprazole (Protonix)
40 mg daily × 4–8 wks
Esomeprazole (Nexium)
20–40 mg daily × 4–8 wks
Risks of Long-Term PPI Use
PPIs are among the most prescribed medications in the US, and for many patients with chronic GERD they are essential for quality of life and esophageal protection. However, long-term use carries potential risks that warrant periodic reassessment:
C. difficile colitis
Reduced gastric acid increases susceptibility to C. diff, particularly in hospitalized patients or those taking antibiotics
Bone fracture risk
Long-term PPI use associated with modest increase in hip, spine, and wrist fracture risk — particularly relevant for postmenopausal women
Vitamin B12 deficiency
Reduced gastric acid impairs B12 absorption from food; supplementation or periodic monitoring may be warranted in long-term users
Hypomagnesemia
Low magnesium levels possible with prolonged PPI use; may cause muscle cramps, cardiac arrhythmias
your provider will review your PPI use, recommend the lowest effective dose, and consider step-down therapy or H2 blocker substitution when clinically appropriate.
Alarm Symptoms — When to Seek Urgent GI Evaluation
The following symptoms alongside heartburn or GERD require urgent evaluation and should NOT be managed with telehealth alone. Seek in-person evaluation or go to the emergency room:
- • Dysphagia — difficulty swallowing solids or liquids; may indicate stricture, ring, or esophageal malignancy
- • Odynophagia — painful swallowing
- • Unintentional weight loss — requires GI referral and endoscopy
- • Hematemesis — vomiting blood; go to ER immediately
- • Melena — black, tarry stools indicating upper GI bleeding; go to ER immediately
- • New-onset GERD symptoms after age 60 — increased risk of Barrett's esophagus and esophageal adenocarcinoma; endoscopy recommended
- • Iron-deficiency anemia without obvious explanation — may indicate occult GI bleeding
Barrett's esophagus — metaplastic change of esophageal lining due to chronic acid exposure — is a precursor to esophageal adenocarcinoma and requires GI specialist follow-up and endoscopic surveillance.
