Helicobacter pylori

　　What diseases can be caused by Helicobacter pylori infection? Shenzhen gastrointestinal experts said that Helicobacter pylori infection can cause chronic gastritis and gastrointestinal ulcer disease. Experts said that the cause of chronic gastritis has not been very clear, so there is no ideal prevention and treatment for a long time. In 1982, Australian scholars observed that a bacterium called Helicobacter pylori (HP) in the gastric mucosa is associated with the onset of chronic gastric disease.

　　 (1) Volunteers with normal gastric mucosa, oral HP suspension can cause gastritis symptoms and pathological changes.

　　 (2) The HP detection rate is very high when suffering from chronic gastritis, but this bacteria cannot be detected in those with normal gastric mucosa.

　　 (3) Serum HP antibody in patients with chronic gastritis is significantly increased, and anti-HP immunoglobulin can be detected in gastric juice, which indicates that HP is a pathogenic antigen (pathogen).

　　(4) Treatment for HP will significantly improve the gastric mucosa of patients with chronic gastritis.

　　 (5) 60%-80% of gastric ulcers and 70%-100% of duodenal ulcer patients can detect HP in the gastric antrum, serological examination confirmed that these human serum HP antibodies Titer is higher.

　　 (6) Treatment of refractory ulcers that are ineffective with traditional anti-ulcer drugs. After switching to anti-HP drugs, most ulcers can heal.

　　(7) Infecting rhesus monkeys with HP can cause chronic gastritis, and the pathological changes of gastric mucosa are similar to human infections, that is, the preparation of HP gastritis animal model has been successful. The above shows that the correlation between HP and chronic gastropathy is undoubted.

　　 Now the medical community has the following consensus: HP must be the causative agent of chronic gastritis, and it is also very closely related to ulcer disease and gastric cancer. That is to say, HP is the culprit and culprit in causing chronic stomach diseases.

　　How to prevent infection

　　 1. The custom of Asians to use chopsticks to eat food in a large bowl allows bacteria in saliva to spread through chopsticks To food and spread each other. Of course, this dining method can also spread other diseases, so Chinese medical scientists have long called for: to change the dining method, it is appropriate to choose a meal-sharing system or use public chopsticks.

　　 2. Scientists have found H. pylori in the drinking water of some Latin American countries. The study also found that these bacteria can survive in river water for 3 years. Experts also confirmed that H. pylori can survive in tap water for 4-10 days. Therefore, to drink boiled water without drinking raw water, eat cooked food without eating raw food, and drink milk after disinfection.

　　 3. Helicobacter pylori enters the human body through the mouth, because this bacterium is often present in the tartar and saliva of patients and carriers. Therefore, paying attention to oral hygiene and preventing diseases from entering the mouth are important measures to prevent Helicobacter pylori infection, prevent stomach diseases and gastric cancer. Many babies in China are infected with Helicobacter pylori. Studies have found that infants infected with Helicobacter pylori are related to oral feeding of a large population. Therefore, parents with Helicobacter pylori must pay attention to this, so as not to affect the health of their children. The high incidence of Helicobacter pylori infection in African children is also the reason why mothers are used to chewing before feeding.

　　 4. Experiments have shown that kissing patients with ulcer disease also has the risk of spreading the disease, so you should be vigilant.

　　 5. Develop good hygiene habits and wash hands before and after meals. Tableware that is frequently used must also be strictly sterilized.

　　 6. Do not put cleaning supplies such as dental appliances in the bathroom, but in a ventilated place. Hygiene also requires frequent ventilation and exposure to sunlight. Ultraviolet lamps can be used on the shaded side of the bathroom for 5-10 minutes.

　　7. Regularly go to the hospital for Helicobacter pylori examination so that it can be detected and treated in time.
