Helicobacter pylori (H. pylori) was classified as a Group 1 carcinogen by the World Health Organization in 1994. There is sufficient evidence in humans of the carcinogenicity of H. pylori infection. Many people suffer from digestive problems such as bloating, gas, acid reflux, heartburn, and stomach discomfort, which are directly related to H. pylori infection. H. pylori is a pathogenic bacterium that is normally found in the stomach and digestive tract and has a very strong tendency to attack the stomach lining. It can also live in our digestive tract for many years and cause stomach ulcers. Chronic H. pylori infection causes degenerative and even transformative changes in the stomach and has been well associated with gastritis and peptic ulcers.

Infection with Helicobacter pylori is very common. Around 70% of the world’s population carries it in their bodies. Generally, 80% of people infected with Helicobacter pylori show no symptoms, and the bacteria can live in the body for years before symptoms begin.

Inflammation or damage to the stomach lining (gastritis) can cause mild to severe reactions to stomach contents, such as stomach or abdominal pain, acid reflux, nausea, and vomiting. Patients with Helicobacter pylori infection may also experience bad breath and frequent hunger.

If left untreated for a long time, Helicobacter pylori infection may be associated with several serious diseases: gastroesophageal reflux disease (GERD), ulcers (duodenal or stomach ulcers), and cancers of the esophagus and stomach.
