There is no one symptom or set of symptoms which may be directly attributed to H. pylori infection. Some of the symptoms that may be associated with infection include nausea, abdominal pain, esophageal reflux, dyspepsia (upper and mid-abdominal pain), bloating, or belching. Conversely, one may be completely asymptomatic for many years.
The only way to know for sure if you have H. pylori is to be tested. The Urea Breath Test offers a simple, noninvasive testing option. Ask your physician for more details.
