GERD vs. NERD: Reflux Management Updates with Dr. James Callaway

Understanding GERD and NERD

• 💡 Gastroesophageal reflux disease (GERD) is defined by troublesome symptoms arising from gastric contents moving into the esophagus.
• 🎯 Non-erosive reflux disease (NERD) refers to reflux without visible erosions on endoscopy, which can still cause significant symptoms.
• 🔑 The distinction between GERD and NERD is important for risk stratification, particularly regarding the potential for complications like esophageal cancer.

Diagnosis and Evaluation of Reflux

• 🔍 Clinical diagnosis of reflux can be made based on history, but objective testing is increasingly recommended, especially for long-term management decisions.
• 🩺 Alarm symptoms such as dysphagia, bleeding, anemia, or weight loss warrant further investigation.
• 📊 Ambulatory reflux monitoring (e.g., wireless capsule or nasal probe impedance-pH testing) provides objective data on acid exposure and reflux burden.
• 🔬 Endoscopy is crucial, ideally performed off PPI therapy, to assess for erosive esophagitis, Barrett's esophagus, or peptic strictures.

Treatment Strategies for Reflux

• 💊 An 8-week trial of a Proton Pump Inhibitor (PPI), such as omeprazole 40mg daily, is a common initial treatment for symptomatic GERD.
• ⚠️ PPIs are more effective than H2 receptor antagonists for symptom improvement and healing esophagitis, but their use should be judicious.
• 📈 Potassium-competitive acid blockers (P-CABs) are a newer class of drugs with a faster onset of action, approved for NERD and being used for severe erosive esophagitis and H. pylori treatment.
• 🥄 Adjunctive therapies like alginates can form a raft to prevent reflux, particularly useful for regurgitation or as additional symptom relief.

Long-Term Management and Considerations

• 🗓️ Long-term PPI therapy is generally recommended for patients with complicated reflux disease (e.g., Class C/D esophagitis, Barrett's esophagus, peptic stricture).
• ⚖️ For patients with NERD or less severe disease, periodic off-PPI trials are encouraged to reassess the need for chronic medication.
• 🩺 Surgical evaluation for hiatal hernia repair may be considered for regurgitation-predominant symptoms refractory to medical management.
• 🧐 Barium esophagrams are helpful for dysphagia but not diagnostic for reflux disease itself.
• 💡 Key takeaways include the importance of objectively defining reflux disease before committing to long-term PPIs and reassessing the need for chronic therapy.
