Helicobacter pylori is a spiral, micro-anaerobic, and very stubborn bacteria. In 1983, it was successfully isolated from gastric mucosal biopsy tissue of patients with chronic active gastritis. It is the only microbial species known to survive in human stomach.

Once, Helicobacter pylori was a strange term. In the past two years, it has suddenly become a household name. In routine physical examination, Helicobacter pylori is often examined. Once it is found to be positive, it will be very worrying, and you can't wait to eliminate it.

The Helicobacter pylori test method includes serological examination, bacterial culture, tissue smear, and urea breath test. Among them, the most urea breath test is easy to be accepted by patients because of its good specificity, sensitivity and non-invasiveness, and can be used for screening and post-treatment review.

The overall population infection rate of Helicobacter pylori in China is about 50%, which is positive. The so-called positive is actually setting a standard. When the amount of bacteria detected exceeds this standard and a certain amount of bacteria is reached, it is considered to be infected.

Among the 1/2 infected people, there are only a few symptoms. Who will need to eradicate the Helicobacter pylori?

1. People who themselves have peptic ulcers must eradicate the bacteria. Because Helicobacter pylori is the cause of ulcers and recurrence of ulcers, if you do not eradicate Helicobacter pylori, even if the ulcer is cured, it will recur after a while.

2. People who have had early gastric cancer surgery must eradicate the bacteria. Long-term Helicobacter pylori infection is a factor in tumorigenesis.

3. Chronic lymphoma in the stomach must be eradicated.

4. Patients with active gastritis need to eradicate the bacteria. Gastroscope found obvious hyperemia, redness, biopsy showed intestinal metaplasia, dysplasia.

5. People who take long-term aspirin drugs are recommended to eradicate the bacteria. Although it is a separate factor, it will work synergistically, so it is recommended to eradicate it.

6. People with gastroesophageal reflux should eradicate the bacteria. Such patients need long-term use of acid-suppressing drugs, the pH of the stomach is reduced, and the environment has changed, which is conducive to the growth of Helicobacter pylori.

7. Uncertain factors. There are obvious symptoms after infection, such as flatulence, eating a small amount of stuff, or subjectively worried people can also consider eradication, but not necessarily, since some people have not relieved symptoms after eradicating the bacteria.

In fact, there are many people who have detected Helicobacter pylori positive, and they do not have the symptoms of digestive tract. In this case, it is not the immediate eradication of bacteria, but a gastroscope should be done. Then according to the results of the gastroscopy, it is decided that eradication will not eradicate.

Why can't you kill Helicobacter pylori?

Because after the eradication, if you live the same way of life, you may still be infected again. This percentage is about 5% per year. Chinese people eat dinner together, and the Helicobacter pylori is spread through diet and saliva, which also makes the infected population high among children. Many habits are not just habits but also a culture. It is not realistic to let the Chinese all eat in a meal-sharing system.

Of course, re-infection is not the main reason for not eradicating. The most important thing is that if it is not properly eradicated, it will make the bacteria get resistant and become even more stubborn.
