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 a more serious infection exhibit symptoms of stomach and duodenal ulcers or severe gastritis which include the following:
- 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 a small amount of food
- decreased appetite that is more constant
