Helicobacter pylori infection
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.
Can a gastroscopy examine Helicobacter pylori?
Can a gastroscopy detect Helicobacter pylori? Helicobacter pylori is a type of bacteria, thus it cannot be seen with the naked eye. However, recent research shows that Helicobacter pylori is closely related to certain mucosal appearances observed under endoscopy. Therefore, endoscopists can infer the infection of Helicobacter pylori based on certain mucosal appearances. However, if a patient is just testing for Helicobacter pylori infection, there is no need for a gastroscopy. We can choose some non-invasive methods such as the carbon-13 breath test, carbon-14 breath test, stool antigen test, and serological antibody test, which are commonly used detection methods. Moreover, after treatment for Helicobacter pylori, it is recommended to choose the carbon-13 or carbon-14 breath test, as they are quite accurate.
How long does Helicobacter pylori resistance last?
Helicobacter pylori resistance generally develops around two weeks. If Helicobacter pylori shows resistance, it is advisable to consider adjusting the treatment using other antibiotics. The eradication treatment for Helicobacter pylori infection generally involves a two-week quadruple therapy with a bismuth-containing regimen. Furthermore, one month after stopping the eradication treatment, it is necessary to recheck with a carbon-13 breath test or a carbon-14 breath test to confirm effective eradication. Helicobacter pylori infection can cause gastritis, peptic ulcers, and malignant tumors in the stomach, among other issues.
Symptoms of Helicobacter pylori infection
Helicobacter pylori, once settled in the stomach and duodenum, can cause chronic inflammation of the gastric mucosa, leading to reduced stomach digestive function. Over time, this may lead to chronic gastritis, gastric ulcers, and even cause gastric cancer. So, what are the symptoms of Helicobacter pylori infection? In cases of mild infection, where the bacteria count is low, there might be no obvious symptoms, with only bad breath occurring. If a high bacteria count causes an inflammatory reaction in the gastric mucosa, symptoms can include stomach bloating, stomach pain, acid reflux, a feeling of fullness in the stomach, along with nausea and bad breath.
Can a gastroscopy detect Helicobacter pylori?
The examination with a gastroscope mainly focuses on checking for any damage to the mucous membranes of the stomach and esophagus. It can detect gastritis, gastric ulcers, or stomach cancer. For some patients who might have a tendency toward cancerous changes, a pathological examination can be conducted. However, testing for Helicobacter pylori with a gastroscope requires a separate lab test. Therefore, routine gastroscopic examinations generally do not include testing for Helicobacter pylori. If testing for Helicobacter pylori is needed, it is a separate examination item. Nowadays, since undergoing a gastroscopy can be quite uncomfortable and cause symptoms like nausea for some people, testing for Helicobacter pylori is accurately conducted using a breath test.
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.
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.
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 barium meal detect Helicobacter pylori?
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.
