Duodenitis caused by ethanol

Last edited: 4/15/2026

Overview

Duodenitis caused by ethanol involves inflammation of the duodenal mucosa primarily due to chronic alcohol consumption, often associated with gastritis and other upper gastrointestinal tract pathologies 1.

Diagnosis

  • Clinical history of heavy alcohol use
  • Endoscopy revealing mucosal erythema, friability, and possible erosions in the duodenum
  • Biopsy may show neutrophilic infiltration and epithelial cell damage
  • Serology and biomarkers are typically not specific but may include elevated liver enzymes 1

    • Management

  • Abstinence from alcohol is crucial 1
  • Proton pump inhibitors (PPIs) for symptom relief and healing, e.g., omeprazole 20-40 mg daily 1
  • Antacids or H2 receptor antagonists as adjunctive therapy for symptom management 1
  • Nutritional support and addressing nutritional deficiencies (e.g., thiamine) in chronic alcohol users 1

    • Special Populations

  • Pregnancy: Abstinence from alcohol is paramount; management focuses on supportive care and nutritional support 1
  • Pediatrics: Limited specific data; focus on alcohol cessation and supportive pediatric gastroenterology care 1
  • Elderly: Increased vigilance for complications; management includes alcohol cessation, PPIs, and addressing comorbidities 1
  • Comorbidities: Consideration of liver disease; management tailored to underlying conditions alongside duodenitis treatment 1

    • Key Recommendations

  • Advise complete abstinence from alcohol to prevent further duodenal mucosal damage and promote healing (Evidence: Strong 1)
  • Initiate proton pump inhibitor therapy to manage symptoms and facilitate mucosal healing (Evidence: Moderate 1)
  • Provide nutritional support addressing deficiencies common in chronic alcohol use, particularly thiamine (Evidence: Expert opinion 1)
