The a Helicobacter pylori, which causes most stomach ulcers, has been present in humans for over 60,000 years. One of the most widespread microorganisms: some researchers claim that only outnumber the bacteria that cause tooth decay. the ulcer, both the stomach and duodenum, is an infectious disease, whose cause is a moving spiral bacteria called a Helicobacter pylori, which is acquired in childhood and lived for many years within the gastric cavity. a Although always produce a small inflammation, most of the time this organism has no symptoms and only causes an ulcer in about one in ten people it infects. In this case the patient is administered a combination of antibiotic drugs, to eliminate the bacterial infection that is restored to its ulceration.

a yet known the exact mechanism by which Helicobacter pylori induces ulcers, but more recent studies suggest that this may be related to the presence in the duodenum of particularly aggressive strains of bacteria capable of producing toxins that can directly injure the surface cells of the digestive system. to this knowledge which are now a proven scientific certainty, and have already been incorporated into health systems protocols and manuals of Medicine, about two decades ago were considered little more than a heresy by many experts skeptical, not believed in the effects of what is now called the a bacteria ulceraa . to the presence of spiral bacteria in the human stomach was first described by Kreinitz in 1906, according to the Spanish Association of Gastroenterology (AEG).
