The most commonly used test for detecting Helicobacter pylori at present is the breath test, which generally comes in two types: carbon-13 and carbon-14, though the testing method is basically fixed. A barium meal test can only detect whether there are large gastric ulcers or the presence of gastric cancer, but Helicobacter pylori is quite small and cannot be detected through a barium meal. Therefore, the detection of Helicobacter pylori typically relies on traditional methods, such as breath tests or tests performed during gastroscopy.

Which department checks for Helicobacter pylori?

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.

Can a gastroscopy check for Helicobacter pylori?

Normally, when conducting a gastroscopy, it is possible to test for Helicobacter pylori, but this method of detection is less commonly used in clinical practice nowadays, as it requires undergoing a gastroscopy, which can be quite distressing and may cause nausea and vomiting. Currently, the main method used in clinical practice for detecting Helicobacter pylori is the breath test, typically using carbon-13 or carbon-14. This involves swallowing a capsule and then blowing into a device to test for Helicobacter pylori infection. This method is more convenient, which is why it has increasingly replaced gastroscopy for detecting Helicobacter pylori.

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.

How to treat Helicobacter pylori infection

Currently, the infection rate of Helicobacter pylori in our country has exceeded 50%. The carbon-14 breath test can be used to detect the presence of Helicobacter pylori infection. If the infection is positive and is accompanied by some symptoms or diseases of the digestive system, eradication treatment for Helicobacter pylori is required. The treatment regimen consists of a proton pump inhibitor, two antibiotics, and a bismuth agent, lasting for 14 days. After stopping the medication for a month, the carbon-14 breath test is rechecked to confirm whether the Helicobacter pylori has been converted to negative. If the conversion is negative, it indicates that the eradication treatment for Helicobacter pylori was successful. Helicobacter pylori has been confirmed as the main cause of chronic gastritis, peptic ulcer, and gastric cancer, thus if the Helicobacter pylori infection is positive, eradication treatment is necessary.

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.
