Exploring the Gut Microbiome's Influence on Peptic Ulcer Disease: Mechanistic Insights, Pharmacological Implications, and Emerging Therapeutic Strategies

Background: The gastrointestinal disorder Peptic Ulcer Disease (PUD) leads to mucosal damage in either stomach or duodenal tissue because of acid-peptic injury. The available evidence demonstrates that Helicobacter pylori (H. pylori) infection and nonsteroidal anti-inflammatory drug (NSAID) usage serve as proven ulcer causes but new research shows the gut microbiome as contributing to ulcer development and therapeutic approaches. Objective: The purpose of this section is to examine the standard H. pylori ulcer development process while examining host immune responses through gut microbial alterations and their effect on PUD disease progression. Methods: This study reviewed multiple research articles to examine how bacteria affect epithelial cells while studying inflammatory pathways as well as microbial metabolites particularly short-chain fatty acids (SCFAs). The review examined different pharmacy-based and natural therapies from the perspective of their ability to modulate the microbiome. Results: The research shows Non-H. Pylori bacteria damage gastric mucosal tissue by activating pro-inflammatory cytokines which leads to gastric homeostasis disturbances because of SCFA production. The ulcer formation gets worse because dysbiosis makes the intestines more sensitive to oxidative stress while simultaneously making the protective mucosal layer weaker. Antibiotics together with proton pump inhibitors affect gut microbial composition but natural treatments including curcumin combined with ginger and probiotics both contribute to microbial recovery and healing of ulcers. Conclusion: Previous research about the gut microbiome's role in PUD pathogenesis forms a base for future development of tailored therapeutic strategies. Combining microbiome-based therapeutic methods with traditional medical protocols produces better management strategies for ulcers with improved healthcare results for patients.
