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.

Do normal people have Helicobacter pylori?

In my understanding, a “normal person” refers to individuals who do not experience any stomach discomfort. In our country, the infection rate of Helicobacter pylori is extremely high, with reports indicating that over 50% of adults are infected, albeit asymptomatically. Thus, it is certain that many so-called "normal people" are infected with Helicobacter pylori, also known as asymptomatic Helicobacter pylori carriers. This condition also requires antibacterial treatment because there is a close relationship between Helicobacter pylori and gastritis, ulcers, and gastric cancer. Even for patients with chronic superficial gastritis, if Helicobacter pylori is present, eradication therapy is advocated. If not completely eradicated, it often leads to the development of chronic atrophic gastritis, which is a more serious condition.

Can you eat sweets during the treatment for Helicobacter pylori?

During the treatment of Helicobacter pylori, it is permissible to eat sweets. During this period, it is necessary to avoid spicy and irritating foods, as well as avoid drinking strong alcohol, strong tea, coffee, and so on. It is recommended to consume more fresh vegetables and fruits rich in vitamins, as well as nutritious and light foods. Smoking and drinking alcohol should be avoided, and meals should be regular and in measured quantities. Since sweet foods are not considered spicy or irritating, they can be consumed during the treatment of Helicobacter pylori. After the treatment of a Helicobacter pylori infection, it is necessary to wait one month after stopping the medication before a follow-up examination to confirm whether the bacteria have been completely eradicated.

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.

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.
