What is H. pylori?

H. pylori is a type of bacteria that resides in the stomachs of about half the global population, often harmlessly [1]. Yet, it can lead to stomach ulcers, presenting symptoms such as abdominal burning, nausea, loss of appetite, and bloating [1]. If untreated, H. pylori can escalate to chronic gastritis and even stomach cancer, highlighting the importance of early detection and treatment.

Besides its known effects on the stomach, research is broadening our understanding of H. pylori's role in other health issues, including deficiencies in iron and vitamin B12, immune disorders, and functional gastrointestinal disorders. Monitoring H. pylori is crucial for safeguarding and maintaining a healthy microbiome due to its wide-ranging potential impacts [2].
