1. In which environment does HP bacteria live?
The stomach is the main residence of HP. In addition, HP is also found in the mouth (tartar, saliva), in the esophagus, duodenum, colon and Meckel's diverticulum, in places with gastric metaplasia...In the concentrated acidic environment of In the human stomach, Helicobacter pylori is considered the only species of bacteria capable of surviving and growing.
Although they have the ability to live intensely and thrive in the human stomach, outside of the natural environment, their vitality is quite weak and their life span is short.
In addition to the stomach environment, HP exists in the oral cavity, intestinal tract, sinus cavity...
HP bacteria have the ability to survive and thrive in the middle layer between mucus and gastric mucosa, besides They also create their own antagonists, avoiding the body's immunity.
HP bacteria are also detected in canals, ponds, food, feces, water...
In the natural environment, HP bacteria exist in the form of spirochetes and cocci. Helicobacter pylori can only survive in water for a few hours if in spiral form, while in the form of spheres, HP bacteria can survive in water for up to 1 year.

3. In the stomach environment, how long does HP bacteria live?
Habitat affects the lifespan of HP bacteria. In fact, humans determine the lifespan of HP bacteria. In other words, if we don't have any effect on it, it will still live and increase, and when we destroy it, it will die.Due to the body's very high immunity, HP bacteria will never die on its own. In the gastric mucosa environment, HP bacteria multiply and develop because this is a favorable environment for them. Therefore, to completely destroy stomach HP, it is necessary to go to the hospital for appropriate and proper treatment.
4. In addition to the stomach environment, how long does HP bacteria live?

In the soil environment: The lifespan of HP bacteria in the soil environment is several hours after leaving the body. They can change their structure to last longer. Therefore, they are still highly infectious to others if they come into contact with the environment with HP bacteria. In the air environment: Although the air environment does not provide nutrients for HP bacteria to survive, they still have a reserve of nutrients that persist until they find another host. Humidity and temperature outside the air environment will determine the life time of HP bacteria in the environment. In the air, the life time of HP bacteria after leaving the body is determined to be 60 minutes to 4 hours. In water: The time that HP bacteria survive in water is different depending on the water temperature. When HP bacteria are in the form of spheres, they can survive for a long time, in water environments such as ponds and canals, HP bacteria can live up to more than 1 year. When water boils at 100 degrees, the HP bacteria will die. Thus, even out of the body, HP bacteria still have a certain period of existence, their ability to infect is still very high when other people come into contact. Therefore, people need to pay attention to water and food sources to reduce the risk of HP infection.
5. Treatment of HP . bacteria
Due to the widespread use of antibiotics and the patient's non-compliance with the dosage and duration of taking the drug, HP bacteria are resistant to many antibiotics. That makes the treatment more difficult and takes longer.Currently usually choose 4-drug regimen for 2 weeks time
Evaluation of HP eradication effectiveness: After stopping taking antibiotics or bismuth for at least 1 month, stop taking acid-reducing or minimal-acid-neutralizing drugs 2 weeks.
It can be seen that in the stomach environment, HP bacteria have a very strong vitality and proliferate. Therefore, it is necessary to actively protect the body to prevent infection with HP bacteria.
