[Helicobacter pylori and disease].

Helicobacter pylori infection is considered an important health problem due to the fact that there are reports that describe that more than 50% of the world's populations is affected by it. The infection has been associated with multiple diseases, gastric and extra-gastric, whose signs and symptoms are overlooked most of the time. Nowadays diagnostic methods have evolved in such a way that they are available for most of the population. Among the treatment schemes is the triple therapy, which is the most effective because it reaches 90% levels of microorganism eradication. For that reason we considered it of great importance doing a review of the most relevant things in literature about this bacteria and the diseases it is associated.
