In this episode of GI101, host Dr. Christina G. Gonzales, DMSc, MPAS, PA-C, dives into Helicobacter pylori (H. pylori), a gram-negative bacterium strongly linked to gastritis, peptic ulcer disease, and gastric cancer. You’ll learn about its unique mechanisms for surviving in the stomach’s acidic environment, how it damages the mucosa, and the classic clinical scenarios where testing is warranted. We’ll also cover diagnostic options—such as urea breath test, stool antigen, and biopsy—and review first-line eradication therapies, including triple and quadruple regimens.
