Question 5 of 5
A 32-year-old woman presents with a 10-month history of an intermittent burning sensation in the epigastrium that is sometimes related to eating. She has heard about bacteria that can cause gastrointestinal (GI) symptoms. She has had no change in her weight and denies dysphagia. Her laboratory tests are normal. Which of the following would you recommend?
Correct Answer: A
Rationale: The patient presents with dyspepsia. In individuals who are under the age of 45 years and present with no other warning signs (e.g., anemia, weight loss, or dysphagia), a serum qualitative test for H. pylori can be obtained to document H. pylori infection, provided that the patient has no prior history of being treated. A serum IgG can remain positive even after antibiotic eradication. In H. pylori-positive individuals who do not respond to therapy, an upper endoscopy would be the next test. An upper GI series cannot detect H. pylori and is less sensitive than endoscopy in detecting lesions of the esophagus, stomach, and proximal small bowel. Empiric therapy for H. pylori is never recommended.
