Helicobacter pylori is a bacterial infection that affects the mucous membrane on the inner surface of the stomach. By itself, the bacterium almost does not show its presence in the human body, but it can cause quite serious complications.

Step 1

How Helicobacter pylori gets into the stomach remains a mystery to doctors, since so far not a single large study has been carried out that allows you to accurately track the moment the body is damaged by bacteria. But the most obvious of all versions says that the infection occurs through the oral route, that is, a person, without noticing it, simply eats bacteria, independently opening their way into their stomach.

Step 2

The causative agent, called "Helicobacter pylori", is a bacterium-stick, three thousandths of a millimeter in size. These little ones are able to move, they do it with the help of filamentous outgrowths - similar to legs. They settle in the depths of the gastric mucosa, because only there they manage to hide from the aggressive acids contained in the gastric juice. At the same time, these bacteria themselves provoke an increased secretion of gastric juice by producing the enzyme urease, a special type of protein. An increased level of acidity in the stomach contributes to the emergence of foci of chronic inflammation up to the formation of an ulcer.

Step 3

In addition, urease is able to split chemically neutral urea into rather aggressive ammonia and carbon dioxide. It is this property that allowed scientists to detect a hitherto unknown bacterium; in advanced cases, the amount of ammonia becomes so large that it can be detected even in the air exhaled by a person.

Step 4

Doctors speculate that most often bacteria enter the body through direct mouth-to-mouth contact, such as kissing or when a mother chews on solid food before giving it to her baby. The number 2 suspects are water and food contaminated with pathogens. The possibility of transmission of bacteria to humans from domestic animals is also not excluded. In countries with a low level of hygiene, Helicobacter can also spread through the fecal-oral route, when water contaminated with human waste is consumed as food without going through the necessary purification.

Step 5

It is not yet possible to completely protect yourself from being damaged by bacteria. There is no effective vaccination against Helicobacter pylori either. But there is good news as well. It consists in the fact that the disease responds well to treatment, which means that it is not at all a sentence to the patient. Therefore, in case of suspicion of infection with the bacterium Helicobacter pylori, it is necessary to undergo an appropriate examination, and if the diagnosis is confirmed, drink a course of antibiotics to free the stomach from the presence of unwanted colonists.
