Introduction
*Helicobacter pylori* is a Gram-negative, microaerophilic bacterium primarily found in the epithelial tissue near the pyloric region of the human stomach. *H. pylori* infection is the most common cause of chronic gastritis. The bacteria can damage the gastric mucosa by releasing cytotoxins and vacuolating toxins, leading to mucosal congestion, edema, and erosion, thereby triggering gastritis.
Under normal circumstances, Helicobacter pylori (H. pylori) is only one of many factors that can cause gastritis and should not be directly equated with gastritis itself. If discomfort symptoms occur, it is recommended to seek timely medical consultation at a hospital and follow standard treatment procedures under a physician's guidance. Detailed explanations are as follows:
Helicobacter pylori is a Gram-negative, microaerophilic bacterium primarily found within the epithelial tissues near the pyloric region of the human stomach. H. pylori infection is the most common cause of chronic gastritis. It can damage the gastric mucosa by releasing cytotoxins and vacuolating toxins, leading to mucosal congestion, edema, erosion, and thereby triggering gastritis. Long-term H. pylori infection may also lead to gastric mucosal atrophy and intestinal metaplasia, which can progress to gastric ulcers.
After H. pylori infects the gastric mucosa, it can cause a series of pathological changes, such as inflammatory cell infiltration and gastric epithelial mucosal damage, thus inducing gastritis.
