急性胃炎 中国就医指南

Acute gastritis is a sudden-onset inflammatory condition of the gastric mucosa, characterized by edema, hyperemia, erosions, or superficial hemorrhages in the stomach lining. Unlike chronic gastritis, which develops gradually and persists over months or years, acute gastritis manifests rapidly—often within hours to days—and is typically reversible with timely intervention. Pathogenically, it arises from direct mucosal injury or disruption of the gastric mucosal barrier. Key mechanisms include excessive gastric acid secretion, impaired mucus-bicarbonate defense, reduced mucosal blood flow, and oxidative stress. Common triggers are nonsteroidal anti-inflammatory drugs (NSAIDs), heavy alcohol consumption, severe physiological stress (e.g., major surgery, burns, sepsis), ingestion of corrosive substances, bacterial toxins (e.g., *Staphylococcus aureus* food poisoning), or *Helicobacter pylori* infection—though *H. pylori* more commonly drives chronic rather than acute presentations. Viral gastroenteritis, radiation exposure, and autoimmune flares may also precipitate acute inflammation. Epidemiologically, acute gastritis is highly prevalent worldwide, affecting an estimated 15–25% of adults annually, with higher incidence in urban populations, older adults (>60 years), and individuals with comorbidities such as cardiovascular disease or diabetes. Risk factors extend beyond NSAID use and alcohol to include smoking, prolonged fasting, psychological stress, critical illness, chemotherapy, and unregulated herbal or supplement intake. Importantly, while many cases are mild and self-limiting, untreated or recurrent episodes can progress to erosive gastritis, gastrointestinal bleeding, or even gastric ulcers—increasing long-term morbidity. Quality of life impact is substantial: patients frequently report debilitating epigastric pain, nausea, vomiting, early satiety, and postprandial bloating—symptoms that impair daily functioning, reduce work productivity, disrupt sleep, and contribute to anxiety around eating. Dietary restrictions, fear of symptom recurrence, and medication side effects further diminish psychosocial well-being. In severe cases—especially those linked to stress ulcers in ICU settings—acute gastritis may necessitate hospitalization, endoscopic evaluation, and intensive supportive care, amplifying emotional and financial burden. Early diagnosis via clinical assessment, upper endoscopy (when indicated), and *H. pylori* testing enables targeted therapy and prevents complications. Patient education on trigger avoidance, dietary modification (e.g., low-acid, non-irritant meals), and adherence to prescribed proton pump inhibitors (PPIs) or mucosal protectants is essential for sustained recovery and relapse prevention.
