What Is Gastritis?
2. Infections
The most common cause of gastritis is an infection from the H. pylori bacterium. It is a very common bacterium that will usually do us no harm, except for in the more severe cases. Most peoples’ immune system is strong enough to keep them safe against the bacterium, but this is not the case for everybody.
Some people will be born with an inability to protect themselves against bacteria. For others, their vulnerability comes due to diseases that are acquired, and/or certain types of medication. A vulnerability to the bacterium will also sometimes happen as a result of the patient’s lifestyle choices.
