Common Symptoms of H. pylori Infection
Many people infected with H. pylori don’t notice any symptoms at all. When symptoms do occur, they usually come from inflammation of the stomach lining or from ulcers in the stomach or duodenum. Common signs include:
-
Abdominal pain or burning — especially when the stomach is empty
-
Bloating and frequent burping
-
Nausea or occasional vomiting
-
Loss of appetite or early fullness
-
Unintended weight loss
-
Indigestion-like discomfort
These symptoms can vary in intensity and might come and go over time. In severe cases — especially when ulcers are present — people may experience dark, tarry stools or vomiting blood, both of which require immediate medical attention.
