What Is a Stomach Ulcer?
2. Helicobacter Pylori
It is thought that the most common cause of stomach ulcers is a bacterium known as helicobacter pylori. This type of bacteria is very common and is often found in mucus that helps to protect the lining of the stomach. For the most part it is completely harmless, but this is not always the case.
H. Pylori can sometimes cause the lining of the stomach to become inflamed. This can result in damage to the stomach lining, and this can result in an ulcer. It is not completely clear how H. pylori is spread. However, contaminated food and water, and physical contact with other people are strong possibilities.
