Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Helicobacter pylori is a common pathogen causing upper gastrointestinal diseases including gastric ulcer and gastric cancer. Recent epidemiological findings have also shown that it is also related to colon cancer, metabolic syndrome, gut dysbiosis, glycemic control and insulin resistance.

The aim of this study is to investigate whether the gut microbiota and insulin resistance of patients with H. pylori infection are abnormal. In addition, whether drinking fermented milk product with probiotic reduces Helicobacter pylori, improves gut microbiota, and increases butyrate-producing bacteria and insulin resistance.
