H. pylori bacterial infections occur in about two-thirds of the world's population, Healthline states. The bacteria enters the body during childhood and lives in the stomach. The bacteria doesn't cause problems for many people, but in some, it may cause stomach ulcers, cancer or an inflammation called gastritis.

People spread H. pylori primarily due to poor hygiene, Healthline says. It can spread from mouth to mouth, or from fecal matter on hands when children don't wash them properly after going to the bathroom. Sometimes the bacteria can be spread through food and water.

People at higher risk of contracting H. pylori bacterial infections tend to live in developing countries or in crowded housing conditions without hot water to keep living areas clean, Healthline reports. Individuals are also at risk who live with others who are infected with the bacteria.

Antacids can help with the pain caused by H. pylori bacterial infections, Healthline says. Individuals who have relatives with stomach cancer or other serious health problems associated with H. pylori bacterial infection may choose to receive antibiotic treatment even if they don't have symptoms.
