H. Pylori

Helicobacter pylori (H. pylori) is a type of bacteria that infects the stomach lining and is a common cause of gastritis and peptic ulcers. Many people with H. pylori have no symptoms, but in some cases, it can lead to abdominal pain, bloating, and nausea. Diagnosis is done through breath, blood, or stool tests, and treatment usually involves a combination of antibiotics and acid-reducing medications.
