H. pylori (Helicobacter pylori)

Helicobacter pylori, commonly known as H. pylori, is a type of bacteria that lives in the stomach. It can cause various digestive issues, including gastritis (inflammation of the stomach lining) and peptic ulcers (sores in the stomach or intestinal lining). Many people with H. pylori do not experience symptoms, but when they do, common signs can include stomach pain, bloating, and nausea. The infection is often treated with a combination of antibiotics and acid-reducing medications. H. pylori is typically transmitted through contaminated food, water, or by coming into contact with infected individuals.
