What is the normal level of Helicobacter pylori?

Helicobacter pylori lives in various areas of the stomach and duodenum. It can cause mild chronic inflammation of the gastric mucosa, and even lead to gastric and duodenal ulcers and gastric cancer. The Helicobacter pylori index is a prescribed indicator for detecting gastric Helicobacter pylori. If we do not pay attention to our own hygiene, it is easy for our stomach to be invaded by Helicobacter pylori. So how much Helicobacter pylori is considered normal?

Clinical course It is generally believed that the clinical course of Helicobacter pylori infection is as follows: Helicobacter pylori reaches the gastric mucosa through the mouth and settles and infects it, causing chronic, superficial gastritis after weeks or months, and then develops into duodenal ulcer, gastric ulcer, lymphoproliferative gastric lymphoma, chronic atrophic gastritis, etc. after several years or decades, and the latter is the most dangerous factor leading to gastric cancer.

Experts believe that Helicobacter pylori infection increases the risk of gastric cancer by 2.7-12 times. If there is no Helicobacter pylori infection, at least 35%-89% of gastric cancer will not occur. It is a consensus among scholars from various countries that Helicobacter pylori disease is acquired and transmitted. The mode of transmission is still unclear, but the most likely route is oral-oral or fecal-oral transmission, which has been proven by the following experiments: using PCR to detect Helicobacter pylori DNA from the patient's saliva, dental plaque, and feces;

2. Helicobacter pylori was isolated from dental plaque and feces; 3. The same Helicobacter pylori strain was isolated from the feces of multiple members of the same family. Infection Distribution: Helicobacter pylori infects people of different races and regions around the world, and it can be said to be the most widespread chronic bacterial infection among adults. The general trend is that the infection rate of Helicobacter pylori increases with age, about 80% in developing countries and about 40% in developed countries, and is slightly higher in men than in women.

The infection age in my country is about 20 years earlier than that in developed countries. The infection rate for people aged 20-40 is 45.4%-63.6%, and it is as high as 78.9% for people over 70 years old. In addition, the infection rate in northern my country is higher than that in southern China. Like other gastrointestinal infectious diseases, the key to preventing Helicobacter pylori infection is to control the "disease from the mouth". For example, you should wash your hands before and after meals, pay attention to hygiene in diet, especially when eating raw and cold foods. It is a wise choice to adopt the separate dining system when dining in a group. If there is a patient with Helicobacter pylori at home, separate dining should be temporarily adopted until the patient is completely cured.

Detection methods There are many methods for detecting Helicobacter pylori infection, such as biopsy, isolation and culture of Helicobacter pylori, rapid urease test, urea breath test, urine ammonia excretion test, serological tests and polymerase chain reaction. Different hospitals use different methods, but most hospitals use methods that are specific, rapid, and some are non-invasive. Experts warn patients that if they feel stomach discomfort, they should go to a large hospital for a Helicobacter pylori infection test so that they can take medication early and eliminate Helicobacter pylori from the digestive tract as soon as possible to prevent the development of serious stomach diseases.

The antigen specimen for gold-label urease detection is feces, and the antibody specimen is blood, serum, and fingertip blood. Its characteristics are convenience, speed, results in 15 minutes, and it is not restricted by many conditions. The test result was a past infection. The carbon 13 breath test must be performed in the fasting state or two hours after a meal. The patient should not have taken antibiotics, bismuth preparations, proton pump inhibitors or other Hp-sensitive drugs in the past month, otherwise a false negative test result will occur. The charges are relatively high.

The above is the relevant content about the gastric Helicobacter pylori index. We should know that the quality of the stomach is directly related to our health, so paying attention to the gastric Helicobacter pylori index is paying attention to the health of our stomach. We are not children anymore, and we don’t need others to remind us of everything. Sometimes taking good care of ourselves is the greatest benefit.
