胃食管反流病 中国就医指南

Gastroesophageal Reflux Disease (GERD) is a chronic digestive disorder characterized by the abnormal reflux of gastric contents—including stomach acid, pepsin, and sometimes bile—into the esophagus. This occurs primarily due to transient lower esophageal sphincter (LES) relaxations, impaired LES tone, delayed gastric emptying, or hiatal hernia, which compromises the natural antireflux barrier. Pathophysiologically, repeated acid exposure damages the esophageal mucosa, triggering inflammation, oxidative stress, and epithelial remodeling. In susceptible individuals, even non-erosive reflux can provoke hypersensitive esophageal nerves, leading to typical symptoms like heartburn and regurgitation—or atypical manifestations such as chronic cough, laryngitis, asthma-like wheezing, and dental erosion. GERD affects an estimated 15–20% of adults in Western populations and 5–10% in East Asia, though prevalence is rising rapidly in China due to urbanization, dietary shifts (increased intake of fatty, spicy, and processed foods), sedentary lifestyles, and rising obesity rates. Key modifiable risk factors include obesity (especially central adiposity), smoking, alcohol consumption, excessive caffeine or chocolate intake, large meals before bedtime, and certain medications (e.g., calcium channel blockers, nitrates, anticholinergics). Non-modifiable risks include advancing age, male sex (for erosive disease), hiatal hernia, and pregnancy. Untreated or poorly controlled GERD significantly impairs quality of life: patients report disrupted sleep, reduced work productivity, social withdrawal due to meal-related anxiety, and heightened psychological distress—including anxiety and depression linked to symptom unpredictability and fear of complications. Long-term consequences may include Barrett’s esophagus (a precancerous metaplastic change), esophageal strictures, and, rarely, esophageal adenocarcinoma. Early diagnosis—often via clinical evaluation supplemented by upper endoscopy, ambulatory pH-impedance monitoring, or esophageal manometry—is essential to guide personalized management. Lifestyle modification remains foundational: weight loss, head-of-bed elevation, avoidance of trigger foods, and meal timing adjustments. Pharmacotherapy typically begins with proton pump inhibitors (PPIs), which suppress gastric acid secretion effectively; H2-receptor antagonists and alginate-based agents serve as alternatives for milder cases. For refractory GERD or PPI intolerance, advanced options include laparoscopic fundoplication or endoscopic anti-reflux procedures (e.g., radiofrequency energy delivery or transoral incisionless fundoplication). Multidisciplinary care involving gastroenterologists, dietitians, and behavioral health specialists optimizes long-term outcomes and patient empowerment.
