What are the symptoms of H. pylori infections?
Most individuals infected with H. pylori have few or no symptoms. Some may experience a few symptoms from mild gastritis episodes, for example,
- minor belching,
- vomiting, and
- abdominal discomfort.
Often, these symptoms simply go away. However, those individuals who have more serious infection experience signs and symptoms of stomach and duodenal ulcers or severe gastritis which include:
- Abdominal pain and/or discomfort that usually does not wax and wane
- Nausea and vomiting sometimes with blood that is red or the color is like coffee grounds like vomitus
- Dark or tar-like stools (black color of feces due to bleeding ulcers)
- Low red blood cell count due to bleeding
- Full feeling after consuming a small amount of food
- Decreased appetite that is more constant
Other symptoms may include:
If a person has symptoms of black, tarry stools and fatigue they should immediate seek medical help or go to an emergency department to be evaluated for intestinal bleeding.
