Exploring Helicobacter pylori infection, diagnosis, and prospect

Helicobacter pylori is a gram-negative, short helical, S-shaped microbe that is 0.5-1 micrometer broad and 2-4 micrometer long. It causes chronic gastric infections and is primarily located in the pyloric area of the stomach. It is believed that almost half of the world's population is infected with these bacteria. Although the precise mechanism of Helicobacter pylori infection and transmission remains unknown, it is believed that the fecal-oral and oral-oral pathways, facilitated by food or water consumption, are prevalent. The pathogenicity, microbial activity, genetic predisposition, and clinical therapies of Helicobacter pylori-induced gastric atrophy and gastric cancer have garnered more attention in the past three decades. Research has indicated that Helicobacter pylori infection may influence the prevalence of malnutrition in specific risk groups and that it may be linked to the inability to absorb vital minerals. An adequate and balanced diet, particularly one that is high in fruits and vegetables and low in processed salty foods, has been shown to have a protective effect against the consequences of Helicobacter pylori infection. On the other hand, dietary factors may play a significant role in H. pylori infection. The current review offers a comprehensive summary of every facet of Helicobacter pylori infection, including advanced treatment and diagnosis.
