A spiral shaped bacteria which causes peptic ulcers, H.pylori (Helicobacter pylori) can be present in many people without causing any symptoms. In the case of infection, you would feel a dull pain in your stomach that seems to come and go, gastritis (inflammation of the digestive tract) bloating and gassiness, nausea, and even bloody vomiting. It is important to diagnose and treat this condition due to its link to stomach cancer if left for a long time. To avoid infection, drinking clean water and personal hygiene before eating and after using the toilet, are essential. In the clinic there are a few ways to diagnose this condition. A simple breath test can show the presence of the bacteria in your digestive system, however, a stool test and an upper endoscopy may be needed. During this procedure a thin, flexible tube with a camera and a light, an endoscope, is introduced through the mouth into the stomach and the duodenum, the start of the small intestine. This can help the doctor diagnose the presence of ulcers in the digestive tract. If you are diagnosed with an H.pylori infection Helicobacter pylori, then you can be given a specific type of antibiotics as well as a proton pump inhibitor that will help with your stomach acid.
