Understanding Helicobacter pylori infection: Symptoms, Diagnosis & Treatment

Helicobacter pylori (H. pylori) is one of the most common chronic bacterial infections worldwide and a major cause of gastritis, peptic ulcer disease, gastric ulcers, duodenal ulcers, gastric cancer, and MALT lymphoma. In this video, we explain in detail what H. pylori infection is, its symptoms, complications, diagnosis, and treatment. You’ll learn how this gram-negative spiral-shaped bacterium survives in the acidic stomach, how it uses urease, adhesins, CagA, and VacA toxins to damage the gastric mucosa, and why it can lead to severe conditions such as gastric adenocarcinoma and lymphoma. We also cover the anatomy and physiology of the stomach, including the roles of parietal cells, chief cells, G-cells, and mucous neck cells, to understand how H. pylori disrupts normal gastric function. Common symptoms of H. pylori include epigastric pain, bloating, indigestion, nausea, early satiety, vomiting, melena, and hematemesis. Diagnostic methods such as endoscopy with biopsy, rapid urease test, histology, stool antigen test, and urea breath test are explained, along with modern treatment approaches like triple therapy (amoxicillin, clarithromycin, PPI) and quadruple therapy.
