Current research suggests that Helicobacter pylori infection is the primary cause of various gastric diseases. It is best to visit the gastroenterology department of a hospital to check for Helicobacter pylori, where a Carbon-14 breath test can be conducted to determine the amount of Helicobacter pylori in the stomach. If there is a high quantity of bacteria, or if there are gastrointestinal diseases present, one might consider a treatment to eradicate Helicobacter pylori. This generally involves the use of two types of antibiotics along with a gastric mucosal protector or a medication that inhibits stomach acid secretion. It is also important to regularly follow up, maintain a regular diet, and avoid spicy and irritating foods.

Is erosive gastritis related to Helicobacter pylori?

Helicobacter pylori infection has been confirmed as the primary cause of chronic gastritis, peptic ulcers, and gastric cancer. Erosive chronic gastritis is a type of chronic gastritis, thus there is a certain relationship between erosive gastritis and Helicobacter pylori, but not all chronic gastritis is caused by Helicobacter pylori; some are, but others are not. Therefore, if erosive gastritis occurs, it is necessary to conduct a carbon-14 breath test to determine whether there is an infection of Helicobacter pylori. If the Helicobacter pylori infection is positive, a 14-day anti-Helicobacter pylori treatment should be administered. The treatment includes a proton pump inhibitor, two antibiotics, and a bismuth agent. After treatment, most of the Helicobacter pylori will convert from positive to negative.

Does everyone have Helicobacter pylori?

Helicobacter pylori is not present in everyone; the infection rate among the general population can reach about 60%. However, some people who are infected with Helicobacter pylori do not necessarily experience symptoms such as acid reflux, bloating, stomach pain, or bad breath. Some people develop symptoms after being infected with Helicobacter pylori, and subsequently, when they visit a hospital for examination, the infection with this bacterium can be detected. Additionally, there are individuals who exhibit such symptoms but are not infected with Helicobacter pylori. In summary, not everyone is infected with Helicobacter pylori, and not everyone who is infected shows symptoms.

What are the symptoms of Helicobacter pylori infection?

Helicobacter pylori is a pathogen produced in the stomach or oral cavity. It cannot be said that Helicobacter pylori causes any specific symptoms, rather, it is the infection of Helicobacter pylori that leads to a series of diseases presenting symptoms. Some people infected with Helicobacter pylori may not show any symptoms at all. If related diseases occur, such as gastritis or ulcers, symptoms such as acid reflux, heartburn, nausea, and vomiting may appear. Additionally, some patients, like those with refractory iron deficiency anemia or idiopathic thrombocytopenic purpura, may also have conditions associated with Helicobacter pylori infection.

How to treat Helicobacter pylori positivity?

A positive test for Helicobacter pylori requires distinguishing the specific method used for detection. If it is a positive result from a Helicobacter pylori antibody test, a breath test, including both the Carbon-14 and Carbon-13 breath tests, should be conducted. If the breath test comes back positive, further examinations are necessary, including gastroscopy and analysis of Helicobacter pylori virulence factors. The analysis of virulence factors can help determine if the Helicobacter pylori infection is highly toxic. If positive, it may indicate a potential for severe gastric diseases and necessitate treatment. For individuals with a positive Helicobacter pylori breath test, a gastroscopy is also recommended, as it is the only way to precisely determine the type of gastric disease present, such as ulcers or gastritis. Depending on the gastroscopy results, some individuals may need eradication treatment for Helicobacter pylori, especially those with a history of gastric ulcers, a family history of gastric cancer, gastric polyps, erosive gastritis, or gastric mucosa-associated lymphoid tissue lymphoma. Others, if the virulence factor analysis is negative, might not require immediate treatment for Helicobacter pylori. However, if a patient insists on treatment for Helicobacter pylori, it can be considered, but it must be clear that there are risks involved and that the treatment should be conducted properly. Finally, treatment for Helicobacter pylori is not recommended for minors, i.e., individuals under 18 years of age.

What should I do if I have a Helicobacter pylori infection?

Helicobacter pylori is closely related to the occurrence of chronic gastritis, gastric ulcers, and gastric cancer, but not everyone infected with Helicobacter pylori will develop chronic gastritis or gastric ulcers. Infections can be diagnosed with a breath test, where values more than twice the normal level, accompanied by symptoms of gastritis, gastric ulcers, stomach distension, stomach pain, and acid reflux, should be considered for antibacterial and stomach-protective treatment. Generally, with standard treatment, 90% of Helicobacter pylori can be eradicated within one to two weeks. However, reinfection is common as it can be found in food and utensils and transmitted through saliva. It is generally advised that children under 14 and individuals with low levels of Helicobacter pylori without obvious stomach inflammation symptoms do not require immediate treatment.
