is amongst the most common chronic bacterial infection in humans. Pediatric patients appear to differ from their adult counterparts in terms of the prevalence, the complication rate, and the rate of antibiotic resistance. In this report, we present an 18-year-old man without any past medical history who was evaluated after an episode of syncope. Evaluation revealed a case of chronic gastritis leading to gastrointestinal (GI) bleeding and weight loss, and his syncope was the byproduct of symptomatic anemia and physical exertion. Pediatricians should think of peptic ulcer disease (PUD) in evaluating poor weight gain/feeding in younger patients, and abdominal pain in older patients. Early diagnosis can prevent complications such as perforation, bleeding and obstruction. Endoscopy is the gold standard of diagnosis for infection. Noninvasive testing with urease breath test and stool antigen test is reserved for post-treatment testing only. Treatment consists of a 14-day course of a proton-pump inhibitor (PPI) and amoxicillin. A third agent, either clarithromycin or metronidazole, is added depending on regional resistance patterns. Testing for eradication at least 4 weeks later is recommended. This case serves as a reminder to primary care providers to be aware of infection, diagnosis, treatment and complications.
